高导电耐温弹性合金(TN-4)系上海交通大学,上海合金厂和杭州电连接器厂共同研制的新型弹性材料,它具有与铍青铜相媲美的优良的导电性和高弹性模量,相当高的强度,良好的延展性和加工性,而抗应力松弛性能却大大优于铍铜,可以承受200℃高温(铍铜最高只能用于150℃)并具有良好的电镀、焊接,抗腐蚀等性能,且生产过程无毒,热处理范围比铍铜宽,价格远低于铍铜,故是一种理想的耐高温导电弹性材料,也可作为优良的代铍铜材料。
High conductivity and temperature resistant elastic alloy (TN-4) is a new type of elastic material jointly developed by Shanghai Jiao Tong University, Shanghai Alloy Factory and Hangzhou Electric Connector Factory. It has excellent electrical conductivity and high elastic modulus comparable to beryllium bronze, Very high strength, good ductility and workability, and the stress relaxation properties are much better than the beryllium copper, can withstand 200 ℃ high temperature (beryllium copper can only be used at 150 ℃) and has a good plating, welding, anti Corrosion and other properties, and the production process non-toxic, heat treatment range wider than beryllium copper, the price is far lower than the beryllium copper, it is an ideal high temperature conductive elastic material, but also can be used as an excellent generation beryllium copper material.
