Zinc (Zn)

Zinc coatings offer higher resistance to corrosion than Nickel coatings and so are ideal for prolonged exposure to water or for outdoor use. Zinc coatings have a silvery matte or dull patina and over time will develop an oxidised protective barrier between the magnetic material and the environment, reducing corrosion and increasing the magnets longevity. Zinc also provides high resistance to abrasion and scratching. Zinc coated Neodymium magnets are used in motors and the Automotive industry.
