Description of Spherical Brass powder
Brass is a versatile metal alloy composed primarily of copper and zinc, with the copper content typically ranging from 60% to 70%, and the balance made up of zinc. The precise ratio of copper to zinc results in different grades of brass, each with distinct physical and mechanical properties.
Copper-zinc alloy powder, also known as brass powder, is the finely milled or atomized form of brass used in various applications including metal coatings, sintered components, metal injection molding (MIM), and additive manufacturing (3D printing). This powder form of brass provides excellent electrical and thermal conductivity, superior resistance to oxidation and corrosion, and an attractive gold-like finish, making it ideal for both functional industrial uses and aesthetic decorative applications.
At Princeton Powder, we are a trusted supplier of spherical brass powder, offering consistent quality and reliable performance for a wide range of manufacturing needs.

Spherical Brass CuZn Powder Reference
Spherical brass powder fabricated by laser scanning
- The irregular particle may melt rapidly and then retract to spherical particle through balling effect by laser beam scanning. The approach of transferring irregular brass powder into spherical powder by laser scanning was explored. The influences of laser power and scanning speed of laser beam and the process of melting, spreading and retracting were analyzed theoretically. The results show that the times of melting, spreading and retracting are very short, which are about 10-5, 10-2 and 10-4 s. And the smaller the particle size is, the quicker the process is. When the laser power was 500 W and scanning speed was 30 mm/s, the spherical brass powder is made from irregular brass powder with diameter of 50μm.
Modern brass is composed of 67 percent copper and 33 percent zinc. Copper concentrations will range from 55 percent to 95 percent by weight, with zinc concentrations ranging from 5 percent to 45 percent. Lead is often applied to brass at a concentration of around 2%.
Red brass usually contains 85% copper, 5% tin, 5% lead, and 5% zinc. Red brass may be copper alloy C23000, which is 14 to 16% zinc, 0.05% iron and lead, and the remainder copper. Red brass also may refer to ounce metal, another copper-zinc-tin alloy.
