Abstract
Description
Technical field [0001] The invention relates to a new material for manufacturing an aluminum piston wear-resistant insert ring, and belongs to the technical field of internal combustion engine materials. Background technique [0002] The material used to make aluminum piston wear-resistant inserts requires similar thermal expansion performance, good wear resistance, and good mechanical and physical properties to aluminum piston materials. To meet this requirement, the composition contains more nickel, higher than 13.5 %, and nickel is expensive, leading to higher material costs and affecting its application. Summary of the invention [0003] The purpose of the present invention is to provide a new material for manufacturing wear-resistant inserts for aluminum pistons, which has low nickel content, low material cost and good application performance. [0004] The material of the present invention for manufacturing wear-resistant inserts for aluminum pistons has a composition of 10...
