全国有21个单位51名专家参加的、航天部主持召开的200℃高温连接器用导电弹性材料(CE-4合金),于1987年10月8～9日在杭州通过技术鉴定。该成果系上海交通大学、上海合金厂与航天部825厂协作研制成功的。CE-4合金具有相当高的强度,良好的延性,比铍青铜高的弹性模量和可相媲美的导电性能,抗应力松弛性能也超过铍青铜。目前已充分掌握其生产工艺,其热处理工艺范围比铍青铜宽。用于Y11产品试制,经历了各种工艺性能、环境,特别是200℃×1000小时例行试验的考核,各项指标完全满足我国第一个圆形电连接器军用标准的要求,填补了国内空白,属围内首创,成本低
The country has 21 units of 51 experts to participate, the Ministry of Space hosted the 200 ℃ high temperature connector with conductive elastic material (CE-4 alloy), in October 1987 October 8 to 9 in Hangzhou through technical appraisal. The achievement of the Department of Shanghai Jiaotong University, Shanghai Alloy Plant and Aerospace Department 825 plant successfully developed. CE-4 alloy with a very high strength, good ductility, high modulus of elasticity than beryllium bronze and can be comparable to the conductivity, stress relaxation resistance than beryllium bronze. Has fully mastered its production process, the heat treatment process wider than the beryllium bronze. For Y11 product trial, has experienced a variety of process performance, environment, especially 200 ℃ × 1000 hours routine test assessment, the indicators fully meet China’s first circular electrical connector military standards, to fill the domestic Blank, is a Wai first, low cost
