Since its establishment for more than 20 years, gemei metal has always been applied to every process of production with strict quality control, and used quality control to guide the production site management, so as to ensure the internal quality, composition and consistency of different batches of product materials.

In the processing of tungsten, molybdenum and its alloys, in order to obtain more objective test data, we gave up self inspection on the chemical composition, mechanical properties, Fischer particle size and other test items of materials, and signed a long-term test cooperation agreement with a nationally qualified third-party testing institution to control the product quality with real test data.
