Bronzes, brasses

Products made from powder material

Use

Powders of copper, bronze, and brass are used to produce filters, and machine parts (friction bearings) using sintering, to deposit wear-resistant, anti-friction, corrosion-resistant and anti-scuffing coatings for the restoration and strengthening of machine parts in the mining and metallurgical industry; auto, streetcar/trolleybus and water transportation; power and oil & gas equipment; and for applying decorative coatings.

Advantages

A wide selection of alloys for solving various challenges in the restoration and strengthening of parts in mechanisms and equipment using thermal spraying and sintering, and in the creation of effective wear-resistant anti-friction and frictional coatings

A fairly wide selection of compressed copper-based materials sprayed with high-pressure water are used to make structural parts and for use as fillers in composites and paints.

There is a wide selection of particle sizes for various uses: less than 40 (45), 20-63, 40-100, 40-60, 63-125, 100-280, 140-315, 160-280, 280-400, 50-315 microns. Powders with other particle sizes can be made at the client's request.

Powders intended for coatings are applied using plasma or gas deposition (thin fractions) and plasma sintering (large fractions) onto steel, using acetylene, propane/butane, compressed air, and the gas-dynamic method.
