本文介绍新型多元银氧化锡铟电触头材料。含氧化锡、氧化铟分别为8.5wt%及4wt%,采用熔炼合金后内氧化工艺制造,为沉淀强化型合金,物理机械性能及抗熔焊性均佳,耐电磨损性好,燃弧时间短,电寿命长,焊接面复有银层易于焊接,且无任何污染。该材料主要用于CJ10及CJ20系列交流接触器的主触头,由于材料性能优良,可缩小触头尺寸,节银率达35.8%以上。
This article describes the new multi-element silver indium oxide electrical contact material. Containing tin oxide, indium oxide were 8.5wt% and 4wt%, respectively, using the smelting alloy after the internal oxidation process for precipitation hardening alloy, physical and mechanical properties and resistance to welding are good, good wear resistance, arc time Short, long electrical life, the welding surface complex silver layer is easy to weld, and without any pollution. The material is mainly used for the main contacts of CJ10 and CJ20 series AC contactors. Due to the excellent material properties, the size of the contacts can be reduced, and the silver section rate is over 35.8%.
