HANGZHOU TENGYE MAGNETIC MATERIALS CO., LTD.

Quality Assurance

Our quality control involves three major areas:

  • in-house produced sintered neodymium magnets
  • outsourced permanent magnets (SmCo, Ceramic and AlNiCo)
  • custom magnetic assemblies

Sintered Neodymium Magnets

The quality of finished neodymium magnets is inspected in three major aspects: magnetic properties, dimensional tolerance and coating quality. By request, the consistency of magnetic performance can be an additional inspection aspect for applications where continuous stability is required
