Abstract: Inversion casting technology is a new way for making cladding materials which have characteristics of high efficiency, low consumption and short technological process. Based on the production of copper clad steel wire, the characteristic of inversion casting is introduced, and the rule of parameter influencing cladding specific value systematically value studied. The experimental results are theoretically analyzed.
Key words: inversion casting; copper clad steel wire; cladding specif ic value
