Abstract

The invention discloses an aluminum, silicon, copper and rare earth alloy material for casting a dual-balance shaft shell of an automobile and a preparation method of the material. The aluminum, silicon, copper and rare earth alloy material comprises the following components (in percent by weight): 10-12 percent of silicon, 1.5-2.5 percent of copper, 0.3-0.9 percent of manganese, 0.1-0.3 percent of rare earth element, 0.18-0.2 percent of impurity element iron and the balance of aluminum. The dual-balance shaft shell of an automobile is made of the aluminum, silicon, copper and rare earth material. The aluminum, silicon, copper and rare earth alloy material has the beneficial effects that the dual-balance shaft shell of the automobile, which is made of the aluminum, silicon, copper and rare earth alloy material, is capable of lightening 2/3 of the weight of an existing dual-balance shaft of the automobile, the corrosion resistance is good, the hardness is high, the hardness (HBM (Brinell Hardness)) of the dual-balance shaft shell of the automobile reaches 80-85, and the tensile strength (theta b) reaches 230-240MPa; the casting yield of the dual-balance shaft shell of the automobile is increased to 90 percent from 80 percent, the thermal treatment procedure is saved, and the production cost is lowered to 5000RMB/ton.

Description

technical field [0001] The invention relates to an aluminum alloy material for metal mold casting and its preparation method and application, in particular to an aluminum-silicon-copper rare earth alloy (AiSiCuRe) material and its preparation method and application. Background technique [0002] my country's automobile industry is developing rapidly. The automobile balancer technology applied to the automobile engine balance system has been maturely promoted and used abroad. This technology can reduce engine vibration, thereby slowing down the vibration of the vehicle, so that the engine can be well balanced. Reduce engine noise, prolong engine life and improve driving comfort. The double balance shaft housing is one of the key components of the engine balancer. This technology is in its infancy in my country. The existing materials for the automobile double balance shaft housing have the problems of heavy weight, poor corrosion resistance, and hardness. Low enough. Content...
