Abstract

The invention provides a thermal bimetal material which comprises the following ingredients in percentage by weight: 40-65% of one of tin, manganese and zinc, 20-35% of iron-nickel alloy, 5-16% of cobalt-based high temperature alloy and 10-30% of inorganic compound particles. The thermal bimetal material provided by the invention has the advantages that the production cost of the thermal bimetal material is reduced, economic benefits are increased, the quality is higher, the electrical resistivity reaches 175 Omega.m, the highest specific thermal deflection rate is 32.5 /DEG C and the thermal bimetal material can replace the conventional high-sensitivity thermal bimetal material.

Description

technical field [0001] The invention belongs to the technical field of metal materials and relates to a thermal bimetallic material. Background technique [0002] Thermal bimetallic material is a functional temperature-sensitive material, composed of two or more materials with different thermal expansion coefficients, which can change its shape according to temperature changes. It is mainly used in thermostats, low-voltage electrical appliances, instruments and meters, etc., such as overload protection for low-voltage circuit breakers. When the current is overloaded, the temperature of the material will rise and the bimetal will bend, thus making the circuit conduction or disconnection. . resulting in high overall costs. Therefore, there is an urgent need to develop a new type of thermal bimetallic composite material with low price and high quality, so as to meet the demand of low-voltage electrical appliances for thermal bimetallic materials.
