我所材料一部焊接研究室,所研制QCu12Z无银中温钎料,与国内常用的含银45％的银基钎料相比,其钎焊工艺性能更好,具有大熔点低、接头强度高、气密性好、耐腐蚀等优点,而且能为国家节约大量贵金属白银。在所科研科的过问下,协调了生产车间的、关系,推 I material a welding laboratory, the development of QCu12Z no silver medium temperature solder, and commonly used in silver 45% silver-based solder, the brazing process better performance, with a large melting point, high joint strength , Air tightness, corrosion resistance, etc., but also for the country to save a lot of precious metals silver. Under the intervenience of the scientific research department, coordinate the production workshop, the relationship, push
