Bronze Specifications

Specifications

An alloy of copper and tin, bronze is often augmented by the addition of other elements in order to produce various key properties. In general terms, bronze is an extremely hard metal - ideal for tough conditions in which wear and tear or longevity are factors. Examples are gears, springs, clips, bearings, and electrical connectors as well as a host of other applications where its pleasing appearance plays an important part; medals, musical instruments and artworks are common uses.

Bronze is produced in two main types, categorised as phosphor bronze and aluminium bronze.

Phosphor Bronzes & Leaded Gunmetal

By adding phosphor, an extremely hard, durable metal is created - ideal for mechanical applications where high levels of wear are a factor.

Aluminium Bronzes

Introducing aluminium produces a material which has excellent resistance to both impact and corrosion. These characteristics make it a primary choice for everything from general engineering to applications in the chemical and marine sectors. It is also commonly used in the manufacture of electrical parts due to its low friction surface.
