The present invention is a high strength lead frame re-dissolved copper (Cu) which improves the hot workability and the softening-nickel (Ni) - manganese (Mn) - silicon (Si) - tin (Sn) - miswi metal (Ms) based alloy and its manufacturing relates to a method, it is an object of high-strength lead frame material based on the cost reduction by reducing the expensive nickel content is added in a large amount in, enhance employment and precipitation strengthening type lead frame material alloy sealed copper-alloy magnesium alloy-nickel-silicon in order to keep the content of oxidizing heavy silicon in the soluble deoxy feature is drop or oxidizing and flammable severe exclusion of magnesium safe and an oxygen capacity and casting cost savings by adding miswi metal excellent immunization effects for the organization, refinement, productivity, to provide a new high-strength lead frame on the safety and re-alloy and its manufacturing method improve the durability of the materials produced. The present invention of the configuration is the copper-nickel-manganese-silicon-tin-miswi metal-based alloy as a 0.5 ~ 5.0 wt% nickel (Ni) and 0.5 ~ 5.0 wt% of manganese (Mn) and 0.1 ~ 3.0 wt% silicon (Si) and addition of 3.0 wt% ~ 0.05 tin (Sn) and 0.001 ~ 1.0 wt% metal miswi (Ms), and the other is a method for producing joseonghan alloy of copper (Cu), and this as a base. ; High-strength lead frame material, copper, nickel, manganese, silicon, tin, metal miswi, hot workability, the softening temperature
