Embodiment 1

[0037] In embodiment 1, the gas furnace on the production line is used to melt the raw materials under the reducing combustion exhaust gas environment, and a charcoal cover is applied in the middle chute and the mold, and the content of P is 0.007 mass %, and the content of Fe is 0.008 % by mass, and the balance is semi-continuous casting of a high-conductivity heat-resistant copper alloy composed of copper and unavoidable impurities to obtain the copper ingot of Example 1. The impurity content composition at this time was 0.007 mass % of Pb, 0.006 mass % of Sn, 0.006 mass % of Zn, and the balance copper was 99.97 mass %. The melting and casting process at this time will be described in detail. When melting raw materials, appropriate materials are selected from commercial waste materials, materials reused in factories, etc., and melted. After that, when the melted sample was extracted and analyzed, the content of P was 0.008% by mass, and the content of Fe was 0.003% by mass....

Embodiment 2

[0043] In embodiment 2, also be the same as embodiment 1, use the gas stove on the production line, raw material is melted under reducing combustion waste gas environment, apply charcoal cover in middle chute and mould, will have the content of P to be 0.005 % by mass, the content of Fe is 0.005% by mass, and the balance is copper and unavoidable impurities by semi-continuous casting to obtain the copper ingot of Example 2. The impurity content composition at this time was 0.002 mass % of Pb, 0.002 mass % of Zn, 0.003 mass % of Ni, and 99.97 mass % of copper in balance.

[0044] At this time, when the sample after melting was extracted and analyzed, the content of P was 0.005% by mass, and the content of Fe was 0.002% by mass. Here, the target value of the composition is set such that the content of P is 0.008% by mass, and the content of Fe is 0.008% by mass, and the components of P and Fe are supplemented in appropriate amounts.

[0045] Thereafter, using the copper ingot o...

Abstract

Disclosed is a copper alloy having both high electrical conductivity and heat resistance, which can be used as a general material for power distribution members or automobile-mounted electrical components for automobiles in which the driving systems are to be electrified. Specifically disclosed is a highly conductive heat-resistant copper alloy which is characterized by having a composition containing 0.004-0.009% by mass of P, 0.004-0.010% by mass of Fe and the balance of copper and unavoidable impurities, namely a composition obtained by blending an iron component into phosphorus deoxidized copper. Since the highly conductive heat-resistant copper alloy does not require an oxygen-free atmosphere during melting / casting in the production process, the copper alloy can be produced by a low-cost production process.
