Bronze Powders & Swarfs

Bronze is an alloy of copper and tin. Bronze may include small proportions of a range of other elements. 

A standard alloy contains approx. 89% copper and 9% tin. Special alloys and the respective particle size distributions are part of the individual specification and are ensured through effective process and quality control.

Alloying and atomization of copper and tin in air produces irregularly shaped Bronze Powder. Deoxidizing components (e.g. phosphorus) can be added to produce powders with light gloss, e.g. those needed in filter materials.

Bronze Powders are manufactured by pulverizing the alloy into flakes as it is flattened by impact from falling stamps into a stamp mill. The pulverized powder fragments are then sorted based on particle size and polished to prepare the final product.
