Cuprodie is a die steel intended for use without water or oil-based lubricants. Some lubricity is provided by low-melting-point copper alloy in this grade. This 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 as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining.
