我院研究开发了一种新材料——铜基高效钎料。经绍兴市自行车飞轮厂前叉焊接生产试用,性能良好,效果显著。该钎料具有明显的优点:含铜量低,且不含有贵重元素和产生有害气体的元素。所含的元素来源充足、价格低廉;冶炼工艺简单、操作方便;熔点低,且熔化温度区间小;钎料和钎焊接头的机械性能优良,具有良好的塑性和韧性,可制成箔和细丝;应用范围广,可用来钎焊钢、铸铁、不锈钢、硬质合金、铜及其合金,尤其适合于盐浴钎焊,可用于汽车、自行车、管道、刀具、制冷机等行业;大幅度降低能耗,改善工人劳动条件。
Our hospital has developed a new material - copper-based high-efficiency solder. The bicycle flywheel factory in Shaoxing City fork welding trial production, good performance, the effect is significant. The brazing filler metal has the obvious advantages of being low in copper content and containing no noble elements and elements generating harmful gases. Containing a sufficient amount of elements, low prices; smelting process is simple, easy to operate; low melting point, and a small melting temperature range; brazing filler metal and brazing joint excellent mechanical properties, good plasticity and toughness, can be made of foil and thin Wire; widely used, can be used to braze steel, cast iron, stainless steel, hard alloy, copper and its alloys, especially for salt bath brazing, can be used for cars, bicycles, pipes, knives, refrigerators and other industries; substantial Reduce energy consumption, improve working conditions of workers.
