Leaded Manganese Bronze
Overview
C86400 is a lower-strength manganese bronze with improved machinability over C86300. It offers good corrosion resistance and moderate strength, making it suitable for general-purpose industrial components.
As a C86400 leaded manganese bronzesupplier, Triton Bronze & Metals stocks continuous cast bronze in round bar, flat bar, castings — all cut to length and shipped from US mills. Every order ships with a mill test report available upon request.
