Plating & Coatings

Plating neodymium magnets is an important process to protect the magnet against its working environment. Below is a list of plantings and their response to certain environments in regards to corrosion, durability, glueability, thickness, and price.

Plating Neodymium magnets is an electrolytic based process and can not be done after the magnet has been magnetized or "charged". All Neodymium Iron Boron magnets mused be plated to avoid oxidization. The majority of magnets we stock are Ni-Cu-Ni plated which is a 3 layer plating of Nickel, Copper, and Nickel. The final silver color nickel layer is exposed.

Nickel (Ni-Cu-Ni)

The most common plating. Ni-Cu-Ni is a durable 3 layer (nickel, copper, nickel coating). Great for indoor use. They may be used outdoors if protected from rain and humidity. Good abrasion resistance.

Zinc Plating (Zn)

Zinc is a standalone (one layer) plating. Zinc is self- sacrificing, meaning when it starts to oxidize the outside turns white creating a durable layer of protection.

Gold (Ni-Cu-Au)

Highly corrosion resistant and conductive. Usually coated with a base layer of Nickel, and copper, to bring out the natural shine of the gold. Works very well in water applications. The gold layer is very but still adds some cost to the magnet.

Black Epoxy (Ni-Cu-BE)

Black Epoxy plating is consists of 3 layers Nickel, Copper, and Epoxy exposed as the top layer. Great for outdoor applications. However, black epoxy is not as abrasion resistant as other platings. In harsh conditions the epoxy layer may be scrached off to expose the copper layer underneath.


Raw Epoxy (BE)

Raw Epoxy is designed specifically for gluing applications where the magnet requires a good adhesion to epoxy glue. This coating consists of one layer of epoxy covering the magnet.

Plastic (ABS)

ABS Plastic is highly corrosion resistant. This coating requires an injection mold to be created in order to encase the magnet. The plastic shell needs to be thicker than other coatings so the plastic can flow during the injection process. Multiple colors available.

Teflon® (PTFE)

Teflon is very resilient and can withstand harsh environments. It is highly corrosion resistant. An injection mold is required to create the shell around the magnet. There will be a noticeable mold seam around the magnet where the injection mold separates.

Everlube®

Everlube is a bonded solid film lubricant coating that can withstand abrasion over an extended period of time. Highly resistant to corrosion and many chemicals.

Xylan®

Xylan coatings are fluorocarbon coatings that contain dry lubricants. Slippery and highly corrosion resistant. Multiple colors available.
