Abstract

The invention relates to a magnesium alloy formula of a starter housing, which contains magnesium, aluminum, zinc, manganese, rare earth, iron, silicon, copper and nickel and does not contain calcium and strontium. AZ91D (magnesium alloy) is used for making a starter front cover, the quality is only 0.4kg, the cutting process is easy, no dust exists, and the labor intensity of workers is low. The starter front cover is made of magnesium alloy materials, thus the weight of each starter can be lightened by 2kg, the cutting process is easy, no dust exists, and the labor intensity of workers is low. The magnesium alloy has very high specific strength and specific stiffness (only inferior to titanium alloy and in the second place in metallic materials), good damping and shock absorption properties, good thermal conductivity, strong electromagnetic shielding capacity and good compatibility with the environment, and can be recovered easily. According to statistics, when the self-weight of an automobile is reduced by 10%, the fuel consumption can be reduced by 5.5%, the fuel economy can be improved by 3%-5%, and simultaneously, the emission can be reduced by about 10%. The invention has practical significance of saving energy sources and reducing environmental pollution.

Description

technical field [0001] The invention relates to a starter housing. Background technique [0002] The material used for the front cover of the starter is mostly cast iron, with a mass of more than 2.5kg, and the processing is difficult, dusty, and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a starter shell magnesium alloy formula to solve the problems of high quality, difficult processing, dust and labor intensity of the starter front cover produced by the cast iron material. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] Magnesium alloy formula for the starter housing, the magnesium alloy formula for the starter housing, the ingredients used include magnesium, aluminum, zinc, manganese, rare earth, iron, silicon, copper, nickel, and do not contain calcium and strontium. [0006] The mass parts of each composition are: [0007] 73.03≤magnesium≤77.41...
