形状记忆、超弹性合金在十几年前曾热闹一时,其后开始了脚踏实地的应用开发和加工技术的改进.近年,由于Ni-Ti合金优异的性能,已开发了携带式电话天线的芯线,眼镜框架等超弹性方面的用途,开发了恒温箱混合水阀用形状记忆合金方面的用途,需求量急剧增加。 携带式电话的天线芯线,以往使用钢琴线、不锈钢线,在日本从1991年开始采用了超弹性合金线。携带式电话的天线人们在拉出或收进时往往操作粗鲁不经心,在天线拉出状态下放入或拿出口袋时,还往往会被挂住,甚至掉落在地。在这种使用条件下,钢琴
Shape memory, superelastic alloy had a bustling ten years ago, then began a down-to-earth application development and processing technology improvements.In recent years, due to the excellent performance of Ni-Ti alloy, has developed a portable telephone antenna core , Spectacle frames and other superelastic purposes, the development of a thermostat tank valve shape memory alloy applications, the sharp increase in demand. Antenna cores for mobile phones, which used piano wires and stainless steel wires in the past, have been used in Japan since 1991 as super-elastic alloy wires. Antennas for mobile phones People tend to be rude and careless when they pull or retract, and often get caught or even dropped when the antenna is pulled in or out of their pockets. Under this condition of use, the piano
