An alloy of copper with 1-5% silicon; it is corrosion-resistant and has good mechanical properties.
A copper alloy having silicon as the main alloying element; zinc, manganese, aluminum, iron, or nickel may be added; high-silicon bronze contains 96% copper and 3% silicon; low-silicon bronze contains 97.7% copper and 1.5% silicon.
The silicon bronzes displayed no problems in casting.
In comparing mechanical properties, the silicon brasses (C87500 and C87800) exhibited the highest tensile properties, followed by the silicon bronzes (C87600 and C97610) and the high-zinc yellow brasses (C85800).
Michels addressed in "Fading of Grain Refinement in Permanent Mold Cast Copper Alloys" (04-112) how grain refinement, or fading, occurs in several materials, such as yellow brasses and silicon bronzes, but at different time lengths.
