    • PURPOSE: A copper alloy, a processed copper article using the same, an electronic part, a connector, and a copper alloy manufacturing method are provided to reduce processing hours by simultaneous solution treatment and recrystallization of a third element through a single solution treatment at low temperatures. CONSTITUTION: A copper alloy manufacturing method is as follows. A copper alloy material, which comprises Ti of 2.0-4.0wt.%, a third element of 0-0.2wt.%, and copper and inevitable impurities of the remaining amount, is heated to a temperature 0-20 °C higher than 730-880 °C and rapidly cooled, where the third element comprises one or two selected from a group consisting of Mn(Manganese), Fe(Iron), Mg(Magnesium), Co(Cobalt), Ni(Nickel), Cr(Chromium), V(Vanadium), Nb(Niobium), Mo(Molybdenum), Zr(Zirconium), Si(Silicon), B(Boron), and P(Phosphorus). The copper alloy material is heat-treated, finally cold-rolled at a processing rate 5-40%, and aged.
    • 目的:提供一种铜合金,使用该铜合金的加工铜制品,电子部件,连接器和铜合金制造方法,以通过单次固溶处理,同时进行固溶处理和再结晶来减少加工时间 温度。 构成:铜合金的制造方法如下。 将包含2.0-4.0重量%的Ti,0-0.2重量%的第三元素以及剩余量的铜和不可避免的杂质的铜合金材料加热至高于730℃的0-20℃的温度 -880℃并迅速冷却,其中第三元素包含选自Mn(锰),Fe(铁),Mg(镁),Co(钴),Ni(镍),Cr(铬)中的一种或两种 ),V(钒),Nb(铌),Mo(钼),Zr(锆),Si(硅),B(硼)和P(磷)。 对铜合金材料进行热处理,最后以5-40%的加工速度进行冷轧,并进行老化。
