Technical characteristics

Cast silicon bronzes Silicon brasses (sometimes also referred to as silicon brass) are copper alloys containing 3.0…4.5% of silicon (Si) and up to 20% of zinc (Zn) as main alloying components. According to the adopted indexation, cast in silicon bronze in the North American standards UNS are denoted by numbers from C87000 to C87999.

Alloying

Silicon bronze alloy may further contain manganese (Mn) and phosphorus (P) as the essential alloying elements. Silicon bronze have a single phase structure (α-phase), moderate mechanical strength combined with very good resistance to moisture and good weldability.

Application

The manufacture of decorative articles, bearings, window fittings, gear wheels, impellers, components of pumps and valves, as well as for manufacturing a variety of sanitary ware.
