Blue white zinc coating is commonly applied for rare earth Neodymium magnets. Blue white zinc coating is generally thinner than the Ni-Cu-Ni coating, the anticorrosion ability of Blue white zinc coating is relatively good.
Neodymium magnets plated with blue white zinc coating can be used in short-term anticorrosion environment.
Specification Information of N48H Grade Neodymium Block Magnets with White Zinc Coating:
The general size range we can produce for the Neodymium block magnets is:Length = 1 - 230mm, Width = 1 – 200mm, Thickness or Height = 1 - 100mm.
The size range we can produce for the max block Neodymium magnets is: The max rectangular Neodymium magnet is L230 × W150 × H50mm, the square Neodymium magnet is L200 × W200 × H20mm.
