High-Leaded Tin Bronze
Overview
C93800 contains a high percentage of lead for outstanding anti-friction characteristics. The lead provides self-lubricating properties, making it an ideal choice for applications where lubrication may be intermittent or difficult to maintain.
As a C93800 high-leaded tin bronzesupplier, Triton Bronze & Metals stocks continuous cast bronze in round bar, hollow bar, castings — all cut to length and shipped from US mills. Every order ships with a mill test report available upon request.
