Description

High-wear-resistance aluminum alloy with new formula

The technical field is as follows:

the invention relates to the field of aluminum alloy, in particular to a high-wear-resistance aluminum alloy with a new formula.

Background art:

the aluminum alloy has low density, high strength similar to or superior to that of high-quality steel, good plasticity, excellent electric conductivity, heat conductivity and corrosion resistance, is widely used in industry, and is second to steel in use amount. Have found numerous applications in the aerospace, automotive, machinery, marine and chemical industries.

Cast aluminum alloys have been used in engines, crankshaft components since 1903, and through the last hundred years of development cast aluminum alloys have evolved into a large series of cast aluminum alloys. Along with social progress, the demand for aviation aluminum and automobile lightweight aluminum is continuously increased, particularly, the requirement on wear resistance in the aspects of pistons and instruments is higher, the aluminum alloy is mainly used as ADC14 at present, and along with the wide use of the turbine increasing technology, the requirement on the wear resistance at high temperature is more urgent.

The aluminum alloy manufactured by the method greatly improves the wear resistance of the product under high pressure and prolongs the service life of the part.

The invention content is as follows:

the invention aims to provide a new formula of high-wear-resistance aluminum alloy, and the obtained aluminum alloy has high mechanical strength and good wear resistance.

The invention also aims to provide the high-wear-resistance aluminum alloy with the new formula, and the formula improves the wear-resistance mechanical property of the aluminum alloy.

The technical scheme adopted by the invention is as follows:
