Abstract

The invention relates to a wear-resistant copper alloy material and a casting method thereof, wherein total seven raw materials, including an aluminum-copper alloy, a nickel plate, pure iron, electrolytic copper, metal manganese, hexachloroethane and cullet, are employed; the CuAl10Ni wear-resistant copper alloy material is obtained through the steps of stove charging, melting, sodium fluoroaluminate doping and sand mold test sample casting, casting molding and the like; and the mechanical properties of the obtained wear-resistant copper alloy material reach the following standards: yield strength B0.2: more than or equal to 270N/mm<2>; tensile strength Bb: more than or equal to 600N/mm<2>; elongation sigma5: more than or equal to 12%; and Brinell hardness HBW: more than or equal to 140; the wear-resistant copper alloy material is specially used for manufacture of the positioning guide sleeve of the air spring of a rail transit vehicle, and has excellent comprehensive mechanical properties, and extremely high abrasive resistance and corrosion resistance; and the service life of the wear-resistant copper alloy material is twice as long as that the service life of the traditional ZCuAl9Mn2(S) material.

Description

technical field [0001] The invention relates to a CuAl10Ni wear-resistant copper alloy material and a casting method thereof; in particular, it relates to a CuAl10Ni wear-resistant copper alloy material and a casting method thereof for a rail transit vehicle air spring positioning guide sleeve product. Background technique [0002] The traditional rail vehicle air spring positioning guide sleeve is made of cast aluminum bronze (ZCuAl9Mn2) according to the national standard GB / T1176-1987, which has the disadvantages of poor comprehensive mechanical properties, poor wear resistance and poor corrosion resistance. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned shortcoming and deficiency, provide a kind of CuAl10Ni copper alloy material and its casting method that a kind of tensile strength and yield strength are high, wear resistance and corrosion resistance are excellent, elongation is high and service life is long; [0...
