Brass Powders Technical Description

Brass powders are manufactured by water-atomising. In addition, we can offer Dendritic Brass Powders (see “Speciality Powders”) produced via a sinter-diffusion bonding route to give irregular, spherical and dendritic morphologies respectively. Properties and, therefore, uses vary with particle shape / size / surface area, composition and by carefully selecting the correct grade, brass powders find applications in diverse markets and technologies.

Our brass powders are characterised by

Tight chemical control
Low lead (Pb) content
Good sinterability
Highly reproducible batch after batch
Available in a variety of UN-approved packaging options including  steel drums (50-100kg) and Big Bags (250, 500, 1000kg).

Brass Metal Powder

Brass metal powders are alloys composed of copper and zinc. It is used in various industries such as electronics because of its extremely low friction coefficient, excellent corrosion resistance, and thermal conductivity. Brass Screening/Sieving As with many metal powders, the density of the powders can cause problems in screening brass powders. Heavy metal powders accumulate on the screen in conventional sieving machines, causing clogging, and sieving efficiency is sometimes reduced.

Physical property

There is a wide variety of sizes distribution, such as granules, powders, strips, and wires.

Chemical properties

Standard alloy represented by Brass Metal & Powder
a) Cu=55%/Zn=45%.
b) Cu=65/Zn=35%.
c) Cu = 70%/Zn = 30%,
d) Cu = 80%/Zn = 20%,
e) Cu=85%/Zn=15%
f) Cu = 90%/Zn = 10

Type of brass Metal

Admiralty brass contains 30% zinc and 1% tin, and it suppresses dezincification in most environments.
Aich’s alloy contains 60.66% copper, 36.58% zinc, 1.02% tin and 1.74% iron. It is excellent in corrosion resistance, hardness, and toughness and is designed for ships. Its unique use is to protect the ship’s bottom, but recently it has become less popular due to the development of cathodic protection. Its appearance resembles gold.
α brass with a zinc content of 35% or less is malleable, can be cold worked, and is used for press and forging. It has a face-centered cubic crystal design and retains only one phase. Prince metal is a type of α brass with 75% copper and 25% zinc. It was used as an imitation of gold because of its beautiful yellow color and was named after Rupert of the Rhine River.
Α-β Brass (Man metal), also called double Brass, contains 35-45% zinc and is suitable for hot processing. αβ brass is usually hot worked.

Brass metal powders Conclusion

The fine, high-purity brass powder is used as a raw material for cold casting in casting resins such as polyester, epoxy, and fast-casting polyurethane resins to create the appearance and feel of genuine metal brass. Further, it is added in a considerable amount to a resin mixture and used as a filler to enhance the casting material’s density and thermal conductivity. Cold casting is a term used to describe mixing the metal powder into resin to create castings with a metallic appearance. The stern casting of metals is a fast and much cheaper process than casting molten metals (the lost wax method).
