Copper Base Alloys for Precision Investment Casting

Copper-base alloys have a predominant component of copper and include brass, bronze, copper and nickel. They are commonly used for marine and electrical applications because they provide high thermal conductivity and excellent corrosion resistance, ductility and toughness.

Brass contains copper and zinc and is typically used for non-sparking tools, plumbing components and valves. Bronze contains copper, tin and other metals and is widely used to investment cast components used by the marine industry. Copper-nickel alloy is also used for marine applications because of its high corrosion resistance.

Additional benefits of using copper-base alloys for precision investment casting include:

  • High melting point
  • Low wear
  • Good ductility
  • High electrical conductivity


Precision Investment Casting for Copper-Base Alloys 

Investment casting is an effective and efficient process because it allows for tight tolerances and is capable of producing intricate cores and passages. Engineered Precision Casting Company, Inc. pours over 75 ferrous and non-ferrous alloys in sizes up to 16 x 16 in. and weights up to 150 lbs.

Our investment casting process is performed in-house using a master heat approval system that runs two dedicated lines for air-melt alloys. We also provide a range of secondary and support services including welding, finishing, CNC machining and heat treating to deliver a complete product that meets your exact requirements.
