Abstract

The invention provides a high-strength anti-oxidation alloy material and a preparation method thereof. The high-strength anti-oxidation alloy material consists of a core and a copper coated layer. The core consists of the following components in percentages 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% of inevitable impurities and the balance of iron. The strength and the oxidation resistance of a melt alloy material are improved, and the problems that alloy melt deforms due to low strength and electric resistance of the melt is affected by oxidation are avoided effectively.

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...
