Abstract

The invention discloses a method for preparing high-strength copper alloy wire rods. The method is characterized by comprising, by mass, 0.6% to 0.9% of Mg, 0.5% to 0.8% of Cr, 0.3% to 0.4% of Mn, 0.6% to 0.8% of Sn, 0.4% to 0.5% of Si, 0.3% to 0.4% of Nb, 0.07% to 0.08% of Mo, 0.06% to 0.07% of Fe, 0.04% to 0.05% of Co, 0.04% to 0.05% of Ce, 0.02% to 0.03% of Y and the balance copper and inevitable nonmetallic inclusions. The preparing technology is easy to operate, practicable, low in production cost and suitable for producing the high-strength and high-conductivity copper alloy wire rods in medium-small batches. The tensile strength of the high-strength and high-conductivity copper alloy wire rods prepared with the technology is larger than 520 MPa, the electric conductivity of the high-strength and high-conductivity copper alloy wire rods prepared with the technology is larger than 80%, and relation matching is good.
