Abstract

The invention discloses a copper alloy material for motor equipment and a preparation method thereof. The copper alloy material is composed of the following components of, by weight, 0.8-1.1% of zinc,0.8-1.1% of tin, 0.4-0.6% of manganese, 0.4-0.6% of nickel, less than or equal to 0.03% of the inevitable impurity iron, less than or equal to 0.03% of the inevitable impurity lead, and the balance copper. The selected materials are relatively low in price, the tin element, the zinc element, the manganese element and the nickel element are used for replacing silver, the manufacturing cost of thematerial is reduced on the premise that the conductivity of the alloy material is guaranteed, and meanwhile, the strength and the hardness of the material are improved; the effectiveness hardening treatment effect of the material is improved, and the material can be used under the environment of 400 DEG C; and the service life of the material in a locomotive electronic conductive part is improved.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a copper alloy material for electrical equipment and a preparation method thereof. Background technique [0002] TAg0.1 silver-copper alloy is an alloy material, which is used to increase the softening temperature (recrystallization temperature) and creep strength. The material has good wear resistance, electrical conductivity and corrosion resistance. For example, when made into a trolley wire, the service life is 2-4 times longer than that of ordinary hard copper; and it has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance. , can be welded and brazed; but the effective hardening effect of this material is not significant, and it is easy to cause "hydrogen disease", so it is not suitable for processing (annealing, welding, etc.) and use in a reducing atmosphere at high temperature (such as >370°C); therefore, Cold hardening i...
