aluminum silicon alloy powder for 3d printing

aluminum silicon alloy powder for 3d printing

Short Description:

Aluminum-silicon alloy powder is an important metal powder material, which is composed of a mixture of aluminum and silicon in different proportions and synthesized by high temperature reaction. The alloy powder has good corrosion resistance, good electrical conductivity and machining performance. And can be made into various shapes of parts by pressing, sintering and other processes.

    Quality control system


    Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.

    Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
