Embodiment 1

[0019] Alloy materials are prepared from high-quality metal titanium, chromium, zirconium, vanadium, cerium, and electrolytic copper. The design masses of each group are: 0.7 kg of high-quality metal titanium, 0.034 kg of chromium, 0.06 kg of vanadium, 0.018 kg of zirconium, and 0.004 kg of cerium 19.184 kg of electrolytic copper (loaded into a 25 kg vacuum induction furnace step by step) The operating procedure is as follows: titanium + chromium + zirconium + cerium + vanadium + copper → melting → refining → condensation → refining → heating → casting

[0020] After casting and forming, the ingot is heated to 870°C and forged into a slab. After the slab is processed, it is heated to 600~850°C and rolled to a solid solution at 850°C. Anneal at 570°C, continue cold rolling and then quench at 850°C, and continue cold rolling the finished product. The total processing rate is controlled between 50-70%, and the finished product processing rate is controlled between 80-85%.

Abstract

The invention relates to a Cu-Ti-Cr-Zr-V high-performance copper-based elastic alloy and a manufacturing method thereof. According to the technical points of the Cu-Ti-Cr-Zr-V high-performance copper-based elastic alloy, electrolytic copper serves as a matrix, chromium, zirconium, vanadium, cerium and titanium serve as main components, and the content of other impurities is smaller than or equal to 0.5%. In a product, the strength of extension ranges from 1,100 Rm/MPa to 1,300 Rm/MPa, the elongation ranges from 8 to 10, the yield strength ranges from 950 to 1,000, and the Vickers hardness ranges from 360 to 380. Compared with beryllium bronze (Be2.0/CY4S) at present, the strength and hardness of the alloy can replace those of the beryllium bronze, and the elongation of the alloy is 4-5 times that of the beryllium bronze. Use of the element Be is avoided through the alloy at the same time, and greater environment friendliness is achieved when a material is prepared and used. The alloy is wide in application, is mainly used as various high-strength and high-elasticity elements such as elastic elements of electric switches and relays, and is widely applied to the fields such as instruments and meters, machine manufacturing, electronics, automobile household appliances, petrochemical engineering, aerospace and ships.
