介绍了电真空器件栅极边杆用料及电子元器件引线用新材料及其加工新工艺。着重陈述了采用铸轧法生产镀镍和镀锡用脱氧铜包铁线的新工艺及生产过程中的关键。与老的电镀法比较,用新工艺生产的产品机械性能、放气性、点焊性、导热性、化学稳定性及表面质量、尺寸公差等均好,价格低、产量高、经济合理。
This paper introduces the new materials and the new processing technology for the materials of the gate side bars and the leads of the electronic components of electric vacuum devices. Emphatically stated the use of casting method for the production of nickel plating and tinning with a new process of copper clad iron wire and the key to the production process. Compared with the old electroplating method, the mechanical properties, deflation, spot weldability, thermal conductivity, chemical stability, surface quality and dimensional tolerance of the products produced by the new process are good, the price is low, the output is high and the economy is reasonable.
