This guide walks through the standard industrial coatings, then the specialty precious-metal and engineered coatings used when corrosion resistance, biocompatibility, conductivity or vacuum-compatibility requirements go beyond what standard plating can offer.<\/p>\r\n <\/div>\r\n\r\n <div class=\"content-card\">\r\n <p class=\"section-title\">Standard Industrial Coatings<\/p>\r\n <p class=\"section-intro\">Most sintered NdFeB magnets in general industrial use are protected with one of four low-cost coatings, covered under <strong>GB\/T 34491 \"Surface Coatings for Sintered NdFeB Magnets\"<\/strong>.<\/p>\r\n <table class=\"coating-table\">\r\n <thead><tr><th>Coating<\/th><th>Typical strengths<\/th><th>Typical trade-off<\/th><\/tr><\/thead>\r\n <tbody>\r\n <tr><td>Nickel-Copper-Nickel (Ni-Cu-Ni)<\/td><td>High mechanical strength, good general corrosion resistance, tolerates heat and thermal cycling well, bright finish<\/td><td>Not the best choice for strong chemical or salt-spray exposure; nickel can trigger skin allergy on direct, prolonged skin contact<\/td><\/tr>\r\n <tr><td>Blue-White Zinc<\/td><td>Low cost, adequate protection for dry indoor use<\/td><td>Weaker moisture\/chemical resistance than epoxy or Ni-Cu-Ni<\/td><\/tr>\r\n <tr><td>Black Epoxy<\/td><td>Strong moisture, chemical and salt-spray resistance; electrical insulation<\/td><td>Organic coating \u2014 outgasses under heat\/vacuum (see Aerospace section below); matte black finish only<\/td><\/tr>\r\n <tr><td>Parylene<\/td><td>Ultra-thin, pinhole-free, strong chemical resistance, biocompatible, low cytotoxicity<\/td><td>Higher cost than Ni-Cu-Ni or zinc; requires CVD equipment\/process control<\/td><\/tr>\r\n <\/tbody>\r\n <\/table>\r\n <\/div>\r\n\r\n <div class=\"content-card\">\r\n <p class=\"section-title\">When to Consider a Precious-Metal or Specialty Coating<\/p>\r\n <p class=\"section-intro\">Standard plating is not chemically inert enough for a handful of demanding applications. In these cases, gold (Au), platinum (Pt), silver (Ag), rhodium (Rh) or an engineered coating such as titanium nitride (TiN) are used instead \u2014 each for a specific, verifiable technical reason, not simply as an upgrade.<\/p>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>1. Implantable & Direct Biomedical Contact<\/h4>\r\n <div class=\"devices\">Cochlear implant magnets, implantable pump\/valve components, magnetic muscle trackers for limb prostheses, magnetic dental attachments<\/div>\r\n <div class=\"coatings\">Titanium encapsulation (dominant practice) \u00b7 Parylene C, gold or TiN direct coating (research\/niche use)<\/div>\r\n <p>Nickel and copper ions released by ordinary plating are cytotoxic and can trigger inflammation or rejection inside the body, so an implanted magnet cannot use standard Ni-Cu-Ni or zinc coating.<\/p>\r\n <div class=\"correction-box\"><strong>Correction to a common assumption:<\/strong> for magnets that are actually implanted in tissue (e.g. cochlear implants), the dominant real-world practice is not direct gold or platinum plating \u2014 it is hermetically sealing the whole magnet inside a welded titanium (or titanium-alloy) housing, so the magnet material never contacts tissue at all. Direct coatings are studied as an alternative for cases where a housing isn't practical: a peer-reviewed 2021 study (Vidal et al., <em>RSC Advances<\/em>) compared gold, titanium nitride and Parylene C as direct coatings on implanted NdFeB magnets and found Parylene C performed best for corrosion prevention and cytotoxicity in muscle-tissue testing \u2014 gold was not the clear winner. Treat \"gold for implants\" as one option among several being researched, not a default.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>2. Strong Chemical \/ Marine Corrosion<\/h4>\r\n <div class=\"devices\">Magnetic stirrers and flowmeters in strong-acid\/alkali chemical processing, chromatography instrument components, seawater-exposed sensors<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Platinum \u00b7 Rhodium<\/div>\r\n <p>Standard Ni-Cu-Ni plating can develop micro-pitting corrosion under strong acid, alkali or high-salinity (e.g. seawater) exposure. Gold, platinum and rhodium are chemically inert enough to resist this, at a materially higher coating cost.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>3. High-Frequency \/ Low-Contact-Resistance Electronics<\/h4>\r\n <div class=\"devices\">Precision micro-connectors, high-frequency relays, precision electronic switches, RF\/microwave magnetic components<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Silver<\/div>\r\n <p>Silver has the highest electrical conductivity of any metal; gold has very low contact resistance and does not form an insulating oxide layer on its surface. When a magnet also serves as an electrical contact or signal path \u2014 not just a magnetic source \u2014 these properties keep contact resistance low and stable over time. Silver also has natural antibacterial properties, which is sometimes a secondary reason for choosing it in medical-adjacent electronics.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>4. Aerospace & Ultra-High Vacuum (UHV)<\/h4>\r\n <div class=\"devices\">Satellite attitude-control systems, space-station precision instruments, UHV physics equipment<\/div>\r\n <div class=\"coatings\">Gold<\/div>\r\n <p>Organic coatings such as epoxy outgas under heat and vacuum, which can contaminate a vacuum chamber or fog nearby optics \u2014 this is exactly what the aerospace industry's <strong>ASTM E595<\/strong> outgassing standard (developed by NASA) screens for, with pass criteria of \u22641.0% total mass loss and \u22640.1% collected volatile condensable material. A dense, non-outgassing gold layer avoids this failure mode and also offers some resistance to radiation and atomic-oxygen erosion in low Earth orbit.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>5. Jewelry, Premium Consumer Goods & Skin-Contact Decorative Parts<\/h4>\r\n <div class=\"devices\">Magnetic jewelry clasps, premium headphone\/smartwatch components, leather-goods magnetic closures<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Rhodium<\/div>\r\n <p>Nickel allergy is common enough that sustained skin contact with a nickel-containing coating is a real concern for consumer products. Gold or rhodium plating gives a premium gold or bright-white finish while fully isolating the skin from the nickel layer underneath.<\/p>\r\n <\/div>\r\n\r\n <p class=\"sub-title\">Other Coatings Worth Knowing About<\/p>\r\n <p class=\"body-text\">The five scenarios above aren't the only specialty options.

This guide walks through the standard industrial coatings, then the specialty precious-metal and engineered coatings used when corrosion resistance, biocompatibility, conductivity or vacuum-compatibility requirements go beyond what standard plating can offer.<\/p>\r\n <\/div>\r\n\r\n <div class=\"content-card\">\r\n <p class=\"section-title\">Standard Industrial Coatings<\/p>\r\n <p class=\"section-intro\">Most sintered NdFeB magnets in general industrial use are protected with one of four low-cost coatings, covered under <strong>GB\/T 34491 \"Surface Coatings for Sintered NdFeB Magnets\"<\/strong>.<\/p>\r\n <table class=\"coating-table\">\r\n <thead><tr><th>Coating<\/th><th>Typical strengths<\/th><th>Typical trade-off<\/th><\/tr><\/thead>\r\n <tbody>\r\n <tr><td>Nickel-Copper-Nickel (Ni-Cu-Ni)<\/td><td>High mechanical strength, good general corrosion resistance, tolerates heat and thermal cycling well, bright finish<\/td><td>Not the best choice for strong chemical or salt-spray exposure; nickel can trigger skin allergy on direct, prolonged skin contact<\/td><\/tr>\r\n <tr><td>Blue-White Zinc<\/td><td>Low cost, adequate protection for dry indoor use<\/td><td>Weaker moisture\/chemical resistance than epoxy or Ni-Cu-Ni<\/td><\/tr>\r\n <tr><td>Black Epoxy<\/td><td>Strong moisture, chemical and salt-spray resistance; electrical insulation<\/td><td>Organic coating \u2014 outgasses under heat\/vacuum (see Aerospace section below); matte black finish only<\/td><\/tr>\r\n <tr><td>Parylene<\/td><td>Ultra-thin, pinhole-free, strong chemical resistance, biocompatible, low cytotoxicity<\/td><td>Higher cost than Ni-Cu-Ni or zinc; requires CVD equipment\/process control<\/td><\/tr>\r\n <\/tbody>\r\n <\/table>\r\n <\/div>\r\n\r\n <div class=\"content-card\">\r\n <p class=\"section-title\">When to Consider a Precious-Metal or Specialty Coating<\/p>\r\n <p class=\"section-intro\">Standard plating is not chemically inert enough for a handful of demanding applications. In these cases, gold (Au), platinum (Pt), silver (Ag), rhodium (Rh) or an engineered coating such as titanium nitride (TiN) are used instead \u2014 each for a specific, verifiable technical reason, not simply as an upgrade.<\/p>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>1. Implantable & Direct Biomedical Contact<\/h4>\r\n <div class=\"devices\">Cochlear implant magnets, implantable pump\/valve components, magnetic muscle trackers for limb prostheses, magnetic dental attachments<\/div>\r\n <div class=\"coatings\">Titanium encapsulation (dominant practice) \u00b7 Parylene C, gold or TiN direct coating (research\/niche use)<\/div>\r\n <p>Nickel and copper ions released by ordinary plating are cytotoxic and can trigger inflammation or rejection inside the body, so an implanted magnet cannot use standard Ni-Cu-Ni or zinc coating.<\/p>\r\n <div class=\"correction-box\"><strong>Correction to a common assumption:<\/strong> for magnets that are actually implanted in tissue (e.g. cochlear implants), the dominant real-world practice is not direct gold or platinum plating \u2014 it is hermetically sealing the whole magnet inside a welded titanium (or titanium-alloy) housing, so the magnet material never contacts tissue at all. Direct coatings are studied as an alternative for cases where a housing isn't practical: a peer-reviewed 2021 study (Vidal et al., <em>RSC Advances<\/em>) compared gold, titanium nitride and Parylene C as direct coatings on implanted NdFeB magnets and found Parylene C performed best for corrosion prevention and cytotoxicity in muscle-tissue testing \u2014 gold was not the clear winner. Treat \"gold for implants\" as one option among several being researched, not a default.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>2. Strong Chemical \/ Marine Corrosion<\/h4>\r\n <div class=\"devices\">Magnetic stirrers and flowmeters in strong-acid\/alkali chemical processing, chromatography instrument components, seawater-exposed sensors<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Platinum \u00b7 Rhodium<\/div>\r\n <p>Standard Ni-Cu-Ni plating can develop micro-pitting corrosion under strong acid, alkali or high-salinity (e.g. seawater) exposure. Gold, platinum and rhodium are chemically inert enough to resist this, at a materially higher coating cost.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>3. High-Frequency \/ Low-Contact-Resistance Electronics<\/h4>\r\n <div class=\"devices\">Precision micro-connectors, high-frequency relays, precision electronic switches, RF\/microwave magnetic components<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Silver<\/div>\r\n <p>Silver has the highest electrical conductivity of any metal; gold has very low contact resistance and does not form an insulating oxide layer on its surface. When a magnet also serves as an electrical contact or signal path \u2014 not just a magnetic source \u2014 these properties keep contact resistance low and stable over time. Silver also has natural antibacterial properties, which is sometimes a secondary reason for choosing it in medical-adjacent electronics.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>4. Aerospace & Ultra-High Vacuum (UHV)<\/h4>\r\n <div class=\"devices\">Satellite attitude-control systems, space-station precision instruments, UHV physics equipment<\/div>\r\n <div class=\"coatings\">Gold<\/div>\r\n <p>Organic coatings such as epoxy outgas under heat and vacuum, which can contaminate a vacuum chamber or fog nearby optics \u2014 this is exactly what the aerospace industry's <strong>ASTM E595<\/strong> outgassing standard (developed by NASA) screens for, with pass criteria of \u22641.0% total mass loss and \u22640.1% collected volatile condensable material. A dense, non-outgassing gold layer avoids this failure mode and also offers some resistance to radiation and atomic-oxygen erosion in low Earth orbit.<\/p>\r\n <\/div>\r\n\r\n <div class=\"scenario-card\">\r\n <h4>5. Jewelry, Premium Consumer Goods & Skin-Contact Decorative Parts<\/h4>\r\n <div class=\"devices\">Magnetic jewelry clasps, premium headphone\/smartwatch components, leather-goods magnetic closures<\/div>\r\n <div class=\"coatings\">Gold \u00b7 Rhodium<\/div>\r\n <p>Nickel allergy is common enough that sustained skin contact with a nickel-containing coating is a real concern for consumer products. Gold or rhodium plating gives a premium gold or bright-white finish while fully isolating the skin from the nickel layer underneath.<\/p>\r\n <\/div>\r\n\r\n <p class=\"sub-title\">Other Coatings Worth Knowing About<\/p>\r\n <p class=\"body-text\">The five scenarios above aren't the only specialty options.
