Spherical bronze powders produced by air atomisation and available in a wide range of particle sizes and alloy compositions.
The powders are characterised by having good sphericity, low oxygen and lead (Pb) content, excellent particle size distribution control and good batch to batch reproducibility,
Spherical Bronze Powders are used in many applications and markets. Typical uses include resin-bonded friction components, decorative applications such as cold casting and cold metal spay, welding and brazing, diamond tooling, surface engineering, steel-backed bearings (bi-metal strip), filters, bronze-filled PTFE for hydraulic seals, etc.
The table below represents just a selection of available alloy compositions and particle sizes.
