Application

1. Among semiconductor materials, low-melting tin-bismuth alloy materials have low strength, so it is not easy to cause defects such as strains and scratches during the stamping process, which is beneficial to improving the surface quality of stamped parts.

2. Additives for alloy materials and powder metallurgy materials, refine grains, diffuse and strengthen, and change the mechanical properties of materials.
