Copper-Tin Alloy Powder

It is mainly used in powder metallurgy, diamond tools, filter material, bi-metal, and conductive functional materials. The product can be brown or apricot in color and might be irregular spherical in shape with stable shrinkage after sinter. It also has good compressibility and formability, which can improve the compaction strength of the green billet.
