Cuprodie 2 die steel is intended for use without water or oil-based lubricants. Some lubricity is provided by low-melting-point copper alloyed in this grade. The alloy is suitable for hammers where operation without a lubricant/coolant results in low to moderate die operating temperatures. This datasheet provides information on composition, hardness, and tensile properties. It also includes information on heat treating, machining, and joining. Filing Code: TS-576.
