本文就新近研制的一种 Spinodal 型高强度(σ_b=146kgf/mm~2)耐热导电弹性材料——Cu-Ni-Al-Ti 合金的应力松弛特性进行了试验研究,并与传统的导电弹性材料——铍青铜(C17200)进行了比较.测定结果表明,该合金的高温抗应力松弛特性与 C17200相比具有明显的优势,且强度高,无铍毒,价格便宜,加工性能好,是一种极有工业开发价值的新型导电弹性材料.
In this paper, a newly developed Spinodal high-strength (σ_b = 146kgf / mm ~ 2) heat-conducting conductive elastic material Cu-Ni-Al-Ti alloy stress relaxation characteristics were studied and compared with the traditional conductive elastic The material Beryllium bronze (C17200) was compared.The results show that the high temperature stress relaxation characteristics of the alloy have obvious advantages compared with C17200, and the strength is high, no beryllium poison, cheap, good processing performance, is a A great value for the development of new conductive conductive elastic material.
