1. Size Tolerance ( +/-0.05mm )

a. Before grinding and cutting, we inspect the black product tolerance.b. Before and after coating, we will inspect the tolerance by AQL standard.c. Before delivery, will inspect the tolerance by AQL standard.PS: Product size can be customized.

2. Surface TreatmentQ: Do neodymium magnets require surface treatments?A: Yes. If magnets are without surface coating (also named plating), it may rust easily under humid conditions.There have many plating options like Ni-Cu-Ni, Nickel, Zinc, Gold, Black Epoxy, White Epoxy coating and so on.Zn and Ni-Cu-Ni coating are the most popular coating. The magnet with plating will resist the corrosion effectively.

3. Magnetization Direction:

Introduction of Manufacturing ProcessSintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
