Silicon bronze alloys should be selected based on their intended use. Specifically :

  • Silicon Bronze Alloy 651, at 98.5 percent Cu and 1.5 percent Si, is typically best in cold headed parts.
  • Silicon Bronze Alloy 655, at 97 percent Cu and 3 percent Si, is best used for fasteners which must be hot-made.
  • Silicon Bronze Alloy 661, made up of 95 percent Cu, 3 percent Si and 0.5 percent Pb is a solid choice for parts that will require machining.
