Abstract

The invention discloses high-strength high-heat-conductivity beryllium copper alloy. The high-strength high-heat-conductivity beryllium copper alloy comprises, by weight, 2.3%-3.7% of beryllium, 0.2%-0.9% of ytterbium, 3.6%-6% of manganese, 8.2%-12.5% of aluminum, 1.2%-2.5% of rare earth elements, 0.8%-1.4% of titanium and the balance copper. According to the high-strength high-heat-conductivity beryllium copper alloy, the vacuum self-consumable electrode electric arc melting technology is adopted, and double annealing, artificial aging treatment and other operations are conducted later, so that the heat conductivity of the beryllium copper alloy is improved, and meanwhile, the high strength and stability of the beryllium copper alloy are also maintained.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a beryllium copper alloy with high strength and high thermal conductivity. Background technique [0002] Beryllium copper alloy is known as the "king of elasticity" among copper alloys. It not only has high strength and high hardness, but also has the advantages of wear resistance and corrosion resistance. At the same time, it also has excellent casting performance, so beryllium copper alloy is suitable for In many fields, such as the production of various molds, explosion-proof safety tools, wear-resistant parts such as cams, gears, worm gears, bearings, etc. [0003] Although beryllium copper alloy can have high thermal conductivity after heat treatment, its strength will be reduced, and high strength and high thermal conductivity cannot be balanced in terms of performance. Contents of the invention [0004] In order to solve the above problems, the present invention disclose...
