Bronze: Binary alloys of copper and tin are called bronzes and can contain up to 12% tin. Tin content ranges from 4% to 8% in wrought materials or higher if the alloy is used as cast. Alloys containing the higher tin level are particularly suitable for severe operating conditions.

Applications: Heavy duty bearings, bushes and gears, thrust washers, pistons and many others.

Phosphor bronze: An alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%. The phosphorus is added as a deoxidizing agent during melting. These alloys are notable for their toughness, strength, low coefficient of friction and fine grain. The phosphorus also improves the fluidity of the molten metal and thereby improves the castability and improves mechanical properties by cleaning up the grain boundaries.

Applications: Springs, bolts, switch components, masonry fixings & various other items used in situations where resistance to fatigue, wear and chemical corrosion are required e.g. ship's propellers in a marine environment.

Aluminium bronze: A range of bronzes containing up to 14% aluminium  that are strong, tough alloys with excellent resistance to corrosion and wear, making them ideal for a wide variety of engineering applications.

Applications: Manufacture of pumps, turbines, propellers, pressure vessels and is especially suited to marine applications. 

Nickel aluminium bronze: Contains around 10% aluminium with additions of iron and manganese for increased strength and further toughness.

Applications: Surface and submarine naval vessels and are often produced to NES (Naval Engineering Standard) designations.

Silicon bronze & aluminium silicon bronze: Contain silicon to a level of 1% up to around 4% and offer low magnetic permeability.

Applications: Navigation equipment and mine hunting vessel equipment.

Gunmetal: This is a copper-tin alloy similar to bronze, used where resistance to corrosion and/or wear is required. Composition is 88% copper, 8% tin, 4% zinc. The alloys now usually contain lead to improve machining characteristics and bearing properties.

Applications: Valves, pump parts, steam fittings, bearings & bushes, hardware fittings, engine & pressure components.
