Description

Technical field [0001] The utility model relates to an aluminum alloy formula composition, in particular to an aluminum alloy formula used for making hot precision forging connecting rods. Background technique [0002] The connecting rod is the main moving part of the piston compressor, gasoline engine, and diesel engine. It connects the crankshaft and the piston pin. It is stretched and compressed during operation. Its quality directly affects the performance and life of the whole machine. The existing aluminum alloy connecting rods generally have a Si content between 8% and 13%. The material has poor plasticity, cannot be forged, and has poor wear resistance and corrosion resistance. The composition contains expensive nickel and wastes a lot of materials during casting. The cost is rising. If the Si content is reduced, the strength and hardness requirements will not be met. Summary of the invention [0003] The purpose of the utility model is to overcome the defects of the exi...
