Abstract | The invention discloses a high-thermal-conductivity regenerated die-casting aluminum alloy material with a regenerated raw material proportion up to 95%, which comprises the following components in percentage by weight: 9.6-11.5% of Si, 0.75-1.1% of Fe, less than or equal to 0.3% of Mn, less than or equal to 1.0% of Zn, less than or equal to 0.25% of Mg, less than or equal to 0.1% of Ti, less than or equal to 0.1% of Cr, less than or equal to 0.1% of Ni, less than or equal to 0.1% of V, less than or equal to 2.0% of Cu, 0.03-0.05% of Sr, 0.04-0.06% of RE, 0.01-0.02% of B, less than or equal to 0.15% of total impurity elements, less than or equal to 0.05% of single content of the impurity elements and the balance of aluminum. The tensile strength, the yield strength and the elongation of the prepared die casting in the casting state reach 280-350 MPa, 120-150 MPa and 3-6% respectively, and the heat conductivity coefficient can reach 140 W/(m.K) or above.
