Al2O3dispersion strengthening copper alloy and method for producing the same

The invention provides an Al2O3 dispersion strengthening copper alloy and the preparation method thereof. The aluminum content of the raw material is 0.05 to 0.6 wt percent, the content of foreign impurities is not higher than 0.5 wt percent, the basis material is copper; the production process adopts the steps of the whole copper-aluminum alloy powder superficial oxidation oxygen replenishment, ingot casting, internal oxidation, deoxidization, agglomeration, squeezing, cold processing and performance testing, the produced Al2O3 dispersion strengthening copper alloy has the advantages that the intensity and the rigidity are higher, the performance of anti high temperature softening is good, simultaneously, the invention has the good performance of electric conduction and heat conduction, and the invention is the ideal material for producing a resistance welding electrode, the lead frame of an integrated circuit, the conductor rod of an high pressure disconnecting switch and other parts at present.
