Evans’ deep drawn and progressive die bronze stampings
Strong, attractive, economical and corrosion-resistant, bronze is often specified for precision stamping. Properties depend on which bronze alloy is selected.
Traditional bronze is a copper alloy with up to 10% tin. The tin in bronze makes it more resistant to wear than unalloyed copper. Bronzes today are usually stronger and more resistant to corrosion than brass.
Specialty bronzes are typically copper alloys that may contain silicon, manganese, aluminum, lead, iron and other elements, with or without tin.
The variations in bronze composition significantly affect its characteristics. Wearability, machinability, corrosion-resistance and ductility for deep drawing are often considered.
Bronze parts are typically used for bearings, clips, electrical connectors and springs. The Evans Company can stamp and deep draw from these alloys cost effectively, using high speed transfer and progressive presses.
Combro, or commercial bronze, is 90-10, or 90% copper/10% zinc. It is frequently the least expensive, most readily available grade of bronze.
