Bronze Casting

Bronze Investment Castings

Milwaukee Precision Casting, Inc. is a trusted leader in the production of high-quality bronze investment castings, ranging from just a few grams to 25 pounds. We work with a variety of premium bronze grades, including Tin Bronze, Silicon Bronze, Aluminum Bronze, and Manganese Bronze. Bronze Investment Casting is utilized for high precision and details when producing complex components with tight tolerances. Bronze is known to be a trusted material for investment casting due to the nature of less deformation during the process of investment casting. Due to this capability, the end result procut is ensured to maintain shape and dimensions. Bronze allows for a smooth and high quality surface finish. Features of Bronze such as strength, corrosion resistance, and wear resistance make it an excellent choice for Investment Casting.

Aluminum bronze, known for its exceptional ductility and tensile strength, is particularly well-suited for demanding applications like pumps and valves, bearings and bushings, impellers, marine castings, and much more.

We cast most grades of bronze for many industries and applications. We commonly work with bronze casting grades listed below, but are not limited to:

  • C95400/C954
  • C86500
  • C86300
  • C952
  • C956

If you have questions about a particular bronze grade, please give us a call.
