Abstract

The invention relates to a piston aluminum ingot used for a turbo charger car. The piston aluminum ingot solves the technical problem that the mechanical property of an aluminum alloy piston in an engine of an existing car is poor, and aluminum scraps generated in the mechanical finishing process of the piston are wasted. Chemical components of the piston aluminum ingot comprise, by weight percent, 11.8-12.8% of Si, 3.0-3.5% of Cu, 0.7-1.0% of Mg, 2.0-2.5% of Ni, 0.1-0.2% of Ti, 0.09-0.2% of Zr, 0.09-0.18% of V, 0.006-0.02% of P, smaller than or equal to 0.5% of Fe, smaller than or equal to 0.2% of Mn, smaller than or equal to 0.12% of Zn, smaller than or equal to 0.05% of Cr, smaller than or equal to 0.01% of Pb, smaller than or equal to 0.02% of Sn, smaller than or equal to 0.002% of Sr,smaller than or equal to 0.001% of Na, smaller than or equal to 0.005% of Ca, smaller than or equal to 0.005% of Sb and the balance Al. The piston aluminum ingot is widely applied to the car with theturbo charger structure and a plug-in hybrid power car.

Description

technical field [0001] The invention relates to the technical field of aluminum ingot production in the new energy vehicle industry, in particular to a piston aluminum ingot used for turbocharged vehicles. Background technique [0002] The development of new energy vehicles is the focus of the development of the world's automobile industry, and my country has included it among the seven strategic emerging industries. The development of new energy vehicles is the only way for my country to move from a big automobile country to a powerful automobile country. On April 6, 2017, the Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology jointly issued the "Medium and Long-Term Development Plan for the Automobile Industry", pointing out that the development of new energy vehicles in my country has entered the growth period from the cultivation period. Energy vehicles account for more than 20% of au...
