1. Physical property data 

Description: A foil-like copper-zinc alloy ultra fine powder with strong metallic luster

3.Property and stability

The greater the content of zinc, the higher extent of cyan. This material is very easy to absorb oxygen, once shown blue-green in color, it has conversed to copper carbonate. In present of water, acid, sulfur dioxide, ammonia, hydrogen sulfide, etc. it will discolor, tarnish, become dark, and belongs to reactive solid.
