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.

The Magnetic Properties of N48H Grade Neodymium Block Magnets with White Zinc Coating:

Residual Induction - Br = 13.7 - 14.3 kGs / 1370 - 1430 mT.
Coercive Force - Hcb ≥ 12.5 kOe / ≥ 955 kA/m.
Intrinsic Coercive - Hcj ≥ 17 kOe / ≥ 1353 kA/m.
