Abstract (en)

[origin: EP3546607A1] The present disclosure discloses a thermally conductive aluminum alloy and application thereof. The thermally conductive aluminum alloy contains alloying elements, unavoidable impurities and the balance of an aluminum element. Based on the total weight of the thermally conductive aluminum alloy, the alloying elements include: 5.0 to 11.0 wt% of Si, 0.4 to 1.0 wt% of Fe, 0.2 to 1.0 wt% of Mg, less than 0.1 wt% of Zn, less than 0.1 wt% of Mn, less than 0.1 wt% of Sr and less than 0.1 wt% of Cu. The thermally conductive aluminum alloy prepared by the present disclosure has a tensile strength of not less than 250 MPa, a yield strength of not less than 150 MPa, an elongation of not less than 3.5%, and a thermal conductivity of not less than 150 W/(m•K).
