Problems solved by technology

In addition, the drawing process of aluminum-magnesium alloy is prone to work hardening, and repeated annealing is required before the next drawing step, which increases the complexity and cost of the process
[0005] The industry is also trying to use pure zinc or conventional zinc alloys to replace copper alloys in the above fields, but there are filaments that cannot be dr

Abstract

The invention discloses a high-strength zinc alloy that can be drawn into thin wires at high speed, which contains 0.1%-5% copper, 0.01%-0.8% titanium or/and 0.05%-2% nickel by weight. The balance is zinc and other unavoidable impurities, and the content of impurities in the whole alloy is not more than 0.05% by weight. The product of the present invention has high strength, which can reach or even exceed the index of T2 and T3 soft (M) pure copper wires; it has good cold plastic processing performance, such as drawing wires with thinner wire diameters by high-speed drawing process , the thinnest wire diameter can reach φ0.1mm, the processing technology is simple, and it can realize industrial continuous production; it has a high working temperature; it has good corrosion resistance, small intergranular corrosion tendency, and high dimensional stability. Therefore, the present invention can replace the fine-diameter copper alloy wires used in domestic metal elastic plastic tiles, braided wires for coaxial cable shielding, and spring wires.

Description

technical field [0001] The invention relates to the field of new alloy materials, specifically a high-strength zinc alloy with a thin wire diameter of less than φ0.5mm that can be drawn at high speed, and is used to replace copper wire spring pads and coaxial Copper alloy wire below φ0.5mm for braided wire and spring wire for cable shielding. Background technique [0002] Copper and its alloy wires have high strength, excellent high-speed drawing performance and high working temperature, and are widely used in elastic metal plastic thrust tiles, braided wires for coaxial cable shielding, spring wires, etc. However, since the 1920s, with the massive mining and consumption of copper resources, there has been a tense situation of copper resources all over the world. Facing the increasingly high copper price, our country, which is inherently deficient in copper resources, is looking for copper alloy substitute materials. Research is imminent. my country is deficient in copper...
