Aluminium bronze and Phosphor bronze




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.

Aluminum bronze contains copper (90-97%), with other metals such as iron, nickel, manganese, aluminum, and silicon added in small amounts.
phosphor bronze only contains copper (90-95%), with tin being the main addition (5-10%).


Aluminum bronzes are used in marine hardware, shafts and pump and valve components for handling seawater, sour mine waters, nonoxidizing acids, and industrial process fluids. They are also used in applications such as heavy duty sleeve bearings, and machine tool ways.
