Silicon Bronze Round Rod

1/4" dia. rod
5/16" dia. rod
3/8" dia. rod
1/2" dia. rod


Silicon Bronze is one of the most corrosion resistant materials around. It is idea for boats that are used in salt water and a good idea for boats that are used in fresh water.

It's high-strength, corrosion resistance, and resilience and formability make silicon bronze among the most widely used copper alloys. C655 is corrosion resistant against most acids, alkalies, salts and organic chemicals. In addition, C655 is excellent hot and cold workability, along with weldability make this alloy superior for the sculpture and architectural industry.
