Accepted Answer

Plating \ Coating	Descr.	Indoor Use	Abrasion	Humidity	Water	Salty Air / Near Ocean	Salt Water	Glue	Thickness	Price
Nickel (Ni-Cu-Ni)	A very durable multilayer combination of nickel, copper, nickel.	Excellent	Good	Good	Bad	Bad	Bad	Bad	10-20 Microns	Low
Zinc Plating (Zn)	2nd most common plating, Zinc is a standalone plating with only one layer. It is a self- sacrificing coating, meaning when the material corrodes the outside turns white creating a durable layer of protection.	Excellent	Excellent	Excellent	Good	Good	Bad	Good	8-10 Microns	Low
Gold (Ni-Cu-Au)	Well known for its corrosion resistance. Layered in Nickel, Copper & Gold on top. Works very well in water applications. The gold layer is very thin and adds only a few cents per magnet.	Superior	Good	Superior	Superior	Superior	Superior	Bad	10-20 Microns	High
Black Epoxy (Ni-Cu-Be)	Epoxy plating is multilayered in Nickel, Copper, Epoxy. Great for outdoor applications. However, it is not very abrasion resistant and prone to scratching.	Superior	Bad	Superior	Superior	Excellent	Excellent	Good	15-25 Microns	Medium
Raw Epoxy (BE)	This coating does not have underlying coats of Nickel or Copper	Superior	Good	Superior	Superior	Excellent	Excellent	Superior	10 - 20 Microns
Plastic	Plastic is the most corrosion resistant. However its is thicker than other platings. A mold is required to create the plastic shell.	Superior	Superior	Superior	Superior	Superior	Superior	Excellent	250-500 Microns	Medium
Teflon	Very efficient coating widely used in various industries. Waterproof seal to protect the magnet inside.	Superior	Superior	Superior	Superior	Superior	Superior	Bad	250 - 500 Microns	High
Phosphate	Phosphate is a temporary coating that will last only a few months. It is normally used when the magnet is going to be over-molded or encased in a plastic part that will act as the final protective layer.	Good	Bad	Bad	Bad	Bad	Bad	Bad	1-2 Microns	Low
