Bronze powder is a flake powder of copper and zinc alloy that varies in color depending on the alloy ratio and is used in a number of industrial and cosmetic applications.
Bronze is an alloy that is comprised of copper and tin, which can be integrated with other alloying elements such as zinc and tin. It has a deep brown colour and a golden sheen that makes this specific alloy noticeable right away.
The sintering process for bronze alters and enhances some properties, such as: Material strength, Translucency, Thermal conductivity.
Bronze powders are used in powder metallurgy and has many applications, including:
