    摘要: Wear resistant copper or a wear resistant copper base alloy having formed on the outermost surface thereof an oxide layer having a thickness of 10-1000 nm and a layer of an intermetallic compound primarily comprising Cu—Sn having a thickness of 0.1-10 &mgr;m under the oxide film layer is provided; a method of preparing the above-described wear resistant copper or copper base alloy by coating base material copper or a copper base alloy with Sn, preferably performing reflow treatment and then conducting heat treatment is provided; and an electrical part comprising the above-described wear resistant copper or copper base alloy is provided. A terminal made of the alloy according to the present invention which has an appropriate oxide film layer by performing heat treatment can greatly decrease a terminal-insertion force compared with that made of an ordinary copper base alloy which is not subjected to the heat treatment. The wear resistant copper or copper base alloy according to the present invention has a large surface hardness, an excellent slipping property, small contact resistance, an excellent electrical characteristic, as well as the small terminal-insertion force so that it can advantageously be used in an electrical part such as a connector or the like for use in an automobile, a charging socket or the like for use in an electric automobile.

    摘要: A copper alloy for terminals of the Cu—Ni—Sn—P system or Cu—Ni—Sn—P—Zn system and that has a tensile strength of at least 500 N/mm2, a spring limit of at least 400 N/mm2, a stress relaxation of no more than 10%, a conductivity of at least 30% IACS and a bending workability in terms of a R/t ratio of no more than 2. The spring portion or the entire part of such terminals are produced from the copper alloy, and have an initial insertion/extraction force of 1.5 N to 30 N and a resistance of no more than 3 m&OHgr; at low voltage and low current as initial performance. The terminals experience not more than 20% stress relaxation. The alloy is superior to the conventional bronze, phosphor bronze and Cu—Sn—Fe—P alloys for terminals in terms of tensile strength, spring limit, stress relaxation characteristics and conductivity and, hence, the terminals manufactured from such alloys have higher performance and reliability than terminals made of the conventional copper alloys for terminals.
