HIGH-STRENGTH AND HIGH-THERMAL-CONDUCTIVITY MAGNESIUM ALLOY AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2023/241077

A1

A high-strength and high-thermal-conductivity magnesium alloy and a preparation method therefor. The high-strength and high-thermal-conductivity magnesium alloy comprises the following components in percentage by weight: Zn: 5.0-8.0%; Al: 0.5-3.0%; Cu: 0.5-3.0%; Zr: 0.1-1%; Mn: 0-1%; Sr: 0-1%; La: 0.5-3%; Ce: 0.5-3%; and the balance comprising Mg and inevitable impurities. The present invention solves the problem that an existing magnesium alloy cannot give consideration to high thermal conductivity and high strength at the same time. The thermal conductivity of the magnesium alloy is 125-135 W/(m·K), the yield strength is 192-216 MPa, the elongation is 7-10%, and a magnesium alloy product having a complex structure and cannot be manufactured by a deformation process can be manufactured. The preparation method of the present invention is low in cost and convenient for large-scale mass production, and can be widely applied to manufacturing of heat dissipation/heat conduction assemblies in the fields of aerospace, 3C products and automobile parts.
