COLMONOY NO. 84 contains tungsten to harden the matrix and provide for good hard-facing. It is a nickel alternative to cobalt surfacing alloys, for service temperatures up to 1500 F. Boron and Silicon content provide better weldability at lower application temperatures. This datasheet provides information on composition and physical properties. It also includes information on forming, heat treating, machining, joining, and powder metal forms. Filing Code: Ni-433. Producer or source: Wall Colmonoy Corporation.
