Abstract
The invention relates to a CuCrZrTi alloy and a preparation method thereof, and aims at providing a novel high-strength and high-conductivity copper alloy material capable of replacing CuCo2Be and a preparation method of the novel copper alloy material. The alloy comprises the following metals by weight percentage: 0.5-1.2% of Cr, 0.03-0.3% of Zr, 0-0.1% of Ti and the balance of Cu and unavoidable impurities. The raw materials are subjected to vacuum melting, alloying, cast ingot casting, hot extrusion, cold processing, intermediate annealing, vacuum aging heat treatment and machining to form the alloy. The prepared copper alloy has good electrical and mechanical properties, is non-magnetic, resists low temperature, is free from sparks during impact, can replace the CuCo2Be material, and avoids environmental pollution during manufacturing of a toxic element Be and operation of an electric field, and since the prepared copper alloy has the better electrical properties, the commercial application and popularization of the spring contact are more competitive.
