Description of Brass Powder
Brass Powder is a kind of foil-like copper-zinc alloy ultra-fine powder with a strong metallic luster and a scaly powder made of copper-zinc alloy, which exhibits an over-hue of cyan to red light based on the increase of copper content from low to high.

Brass Powder FAQs
Q1: What is brass powder?
Brass powder consists of fine particles of brass, a copper-zinc alloy, known for its yellowish-gold color. The proportions of copper and zinc can vary, which affects the properties of the brass, with typical compositions ranging from 55-90% copper and 10-45% zinc.
Q2: What are the properties of brass powder?
Brass powder is known for its corrosion resistance, good mechanical properties, and excellent malleability and acoustic properties. It also possesses a lower melting point compared to pure copper, making it suitable for various thermal processes.
Q3: How is brass powder produced?
Brass powder can be made through atomization, a process involving the melting of brass followed by spraying it through a high-velocity air or water stream to create fine particles. It can also be produced by grinding or by chemical methods.
