Silicon Bronze
Overview
C65500 is a high-strength, lead-free silicon bronze known for its excellent corrosion resistance and weldability. It is widely used in marine, architectural, and chemical process applications where aesthetics, durability, and lead-free compliance are all important.
As a C65500 silicon bronzesupplier, Triton Bronze & Metals stocks continuous cast bronze in round bar, flat bar, plate, and more — all cut to length and shipped from US mills. Every order ships with a mill test report available upon request.
