Abstract

A high-strength anti-oxidation alloy material and a preparation method thereof provided by the present invention are composed of a core and a copper plating layer, wherein the core is composed of the following components in weight percentage: 42% to 45% of tin and 13% of copper ~ 16%, aluminum 0.5% ~ 1.2%, magnesium 1.2% ~ 1.8%, scandium 0.2% ~ 0.5%, unavoidable impurity content ≤ 2wt%, the rest is iron. Therefore, the strength and oxidation resistance of the melt alloy material are improved, and the deformation of the alloy melt due to low strength and the problem of affecting the melt resistance due to oxidation are effectively avoided.

Description

technical field [0001] The invention relates to the field of melt alloys, in particular to a high-strength oxidation-resistant melt alloy material suitable for fuses and a preparation method thereof. Background technique [0002] 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 circuit and overcurrent protectors, fuses are one of the most commonly used protection devices. [0003] Fuses are generally composed of insulating bases or supports, contacts, melts, etc. The melt is the main working part of the fuse. The melt is eq...
