沈阳重型机器厂为适应重型机器制造发展的需要,坚持“独立自主,自力更生”的方针,在兄弟单位的大力协助下,研制成功了一种无镍高强度耐磨铜合金—高锰铝青铜。经哈尔滨松江电机厂在2000吨精压机肘杆轴瓦上使用,轴瓦面压为2000公斤/厘米~2,速度0.2米/秒,从一九七四年五月至一九七五年十一月,一直运行正常。先后两次拆卸检查,
In order to meet the needs of heavy machinery manufacturing and development, Shenyang Heavy Machinery Factory has adhered to the principle of “independent and self-reliance” and successfully developed a nickel-free high-strength wear-resistant copper alloy-high manganese aluminum bronze with the help of its brother units. The Harbin Songjiang Motor Factory in the 2000 tons of presses on the elbow rod bearing on the use of bearing surface pressure of 2000 kg / cm ~ 2, the speed of 0.2 m / s, from July 1974 to 1975 Month, has been operating normally. Has twice disassembled inspection,
