Shijiazhuang free solder bar manufacturer, Hanson Tin, Tin Lead manufacturer

Welding is formed between the solder and the metal part of bond between Liaoning without Tin manufacturers, solder molecules penetrate the molecular structure of the base metal and the formation of a solid, fully metal structure. When the solder is dissolved, it is impossible to entirely from the metal surface to wipe it off Xi'an free solder bar manufacturer, because it has become part of the base metal. Preparation of tin is relatively simple, including ingredients, smelting and casting two processes, and strictly control the degree of oxidation and metal, non-metallic impurities. Wherein the melting temperature and pouring temperature greater impact on two parameters tin quality. Tin, according to environmental classification, including and without Tin Tin.
