随着电气和电子工业的最新进展,要求作为动能材料的铜合金既具有优异的性能和可靠性,还要求成本低廉。传统的6％锡磷青铜C5191虽具有优异的性能,但其成本太高。日本玉川机械金属株式会社开发了一种含有少量铁的磷青铜,商品名为TNB,其名义成分为4％Sn,0.6％Fe,0.02％P,0.1％ With the latest developments in the electrical and electronics industry, the demand for copper alloys as kinetic energy materials is both superior in performance and reliability and low in cost. Although the traditional 6% tin-phosphor bronze C5191 has excellent performance, its cost is too high. Japan Tamaka Machinery Metal Co., Ltd. developed a phosphor bronze containing a small amount of iron under the trade name of TNB with a nominal composition of 4% Sn, 0.6% Fe, 0.02% P, 0.1%
