Aluminum Bronze Alloys: Featured Information
Background
Chill mold cast parts made from copper aluminum alloys are wear-resistant, corrosion-resistant and resist embrittlement.
Copper aluminum alloys, better known in the industry as aluminum bronze alloys, are the choice alloys for designers when replacing steel weld fabrications with a one-piece PIAD chill casting.
Copper aluminum alloys with iron, nickel and manganese additions have mechanical properties which exceed the mechanical properties of carbon steel and medium alloyed steel. Besides these excellent mechanical properties, PIAD chill cast aluminum bronzes exhibit many additional physical properties which provide excellent choices for design engineers. These alloys can be used in many different industrial environments.
