Abstract

The invention provides a preparation method of high-strength antioxidant alloy materials. The high-strength antioxidant alloy materials comprise a core part and a copper plating layer, wherein the core part comprises, by weight, 42%-45% of tin, 13%-16% of copper, 0.5%-1.2% of aluminum, 1.2%-1.8% of magnesium, 0.2%-0.5% of scandium, less than or equal to 2 wt% inevitable impurities and the balanceiron. The strength and the oxidation resistance of melt alloy materials are improved, and the problems that the alloy melt is deformed caused by low strength, and the resistance of the melt is affected by oxidation are solved.

Description

[0001] This application is a divisional application, the original patent number is: 201710355824.4, the application date is May 19, 2017, and the title of the invention is: a high-strength oxidation-resistant alloy material and its preparation method. technical field [0002] The invention relates to the field of melt alloys, in particular to a preparation method of a high-strength oxidation-resistant melt alloy material suitable for fuses. Background technique [0003] With the continuous development of social economy, electronic equipment has been widely used, and the demand for fuses has also increased. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circui...
