Bronze Products

We are casting aluminium bronze and thin bronze, including many alloy grades. These are alloys of copper and aluminium with additions such as tin, phosphorus, manganese, aluminium or silicon to enhance specific mechanical, physical and fabrication characteristics.

Aluminium bronzes are most valued for their blend of high strength and corrosion resistance. The alloy group is also tarnish resistant and shows low rates of corrosion in seawater and under adverse atmospheric conditions. This corrosion resistance is attributed to a tough layer of aluminium oxide, which forms naturally on the surface of the alloy and acts as a barrier.

Aluminium bronze is often also selected for its wear and abrasion resistance, controlled impact strength, low magnetic permeability, formability and weldability.

Phosphor bronze is an alloy of copper and up to 12% tin. Phosphorus is primarily added as a deoxidant and also improves fluidity and mechanical properties.

Phosphor bronze alloys are noted for their strength and toughness coupled with high corrosion resistance and excellent spring and plating properties. The presence of tin imparts a good wear resistance, especially at higher levels, giving rise to their use in bearing components. They also have good thermal and electrical conductivities and are often used in the electrical and electronic industries.
