Lost foam casting for copper alloys, an exclusive process by Lebronze alloys

Lost foam is an innovative casting process where liquid metal is poured on a foam pattern. The pattern, placed in a casting system filled with sand, is evaporated by the metal, which takes the form of the final part. Lost Foam casting enables high technical and economical performances: tight tolerances, machining savings, metal and energy consumption savings.

Lost foam casting is available for a wide range of alloys:

  • Bronze (CuSn)
  • Aluminum Bronze (CuAl, CuAlFeNi)
  • Brass
  • Low alloyed Copper
  • Other copper alloys on request

Lost foam casting is possible for parts weighting from 100 g to 100 kg.
