Based on the analysis of the effect of the molten iron on the metal type and the requirement of the metal type material in the cast iron metal casting process, on the basis of this, the research and development of the high temperature conductivity, excellent overall performance cast iron pieces of water-cooled metal with chromium zirconium Magnesium copper alloy. Design and manufacture of automotive ductile iron water-cooled copper alloy metal type, and in the production line pilot production. The results show that the zirconium-magnesium-magnesium alloy has good thermal conductivity, good thermal fatigue resistance and thermal stability. The service life of the metal-type primary cavity of the water-cooled copper alloy will exceed 20,000 times and the total service life will exceed 100,000 times
