The Bronze Alloy 937 Advantage

This bronze alloy grade is comprised of approximately 80 percent copper, 10 percent tin, and 10 percent lead. Also called C93700 Bronze or Highly Leaded Tin Bronze, it exhibits natural lubricity and permits dirt particles to become embedded in its surface, thereby protecting mating parts. Other benefits include:

  • Malleable
  • Good Corrosion Resistance
  • Strong
  • Easily Machinable
  • Strong Wear Resistance
  • Excellent Antifriction Qualities
