Double metal (cast iron-copper) friction reduction material is one of the metal base materials. It is a kind of engineering material which organic combines the cheap cast iron with the copper alloy with good friction reduc-ing. Taking cast iron as the matrix, covering the copper alloy powder in its surface, the sintering is suppressed as the friction reducing layer. Cast iron and copper double metal reducing friction materials can play both of the material's advantages. It can not only save a large quantity of valuable metals, but also overcome their disadvantage of two metals with special performance to adapt to a variety of adverse working. And it greatly improves friction material strength reduction and broadens the scope of application. So it has been widely used in automobile engines and heavy-duty crane equipment, and other fields.
