C93700 Tin Bronze Casting
C93700 Tin Bronze Casting (UNS C93700), known as High Leaded Tin Bronze 80-10-10, contains nominally 80% copper, 10% tin, and 10% lead. The high lead content provides exceptional lubricity and conformability, making it ideal for high-speed, low-load bearing applications. Indicative price: US$ 9.50/kilogram (subject to quantity and specification).
