Embodiment Construction

[0012] Below in conjunction with embodiment the present invention is described in further detail.

[0013] The process route of this embodiment is: batching → continuous casting → stretching → annealing → pickling → stretching → finished product → (or finished product annealing) → packaging and storage.

[0014] 1. Invention alloy composition (wt%):

[0015] Ni: 15%, Zn38%, Ti: 0.4%, Zr: 0.1%, Cu: balance

[0016] 2. Alloy melting process

[0017] Raw materials: electrolytic copper, electrolytic nickel, zinc ingot, Cu-6% Ti master alloy, Cu-5% Zr master alloy

[0018] Technical conditions and parameters: continuous casting slab specification: Φ12mm, melting temperature: 1300-1400℃, covering agent: dry charcoal.

[0019] Feeding sequence: electrolytic copper, electrolytic nickel → adding zinc after melting → adding intermediate alloy → pouring into a 300kg holding furnace for heat preservation after melting → the temperature in the holding furnace reaches above 1200°C, sampl...

Abstract

The invention relates to a high-strength zinc-nickel-nickel alloy. The chemical composition of the alloy contains: Zn 38%-45%, Ni 13%-17%, and the balance Cu, wherein the alloy composition includes Cu+Zn+ Ni content ≥ 99.5%. Its chemical composition can also contain: one or two of the three elements Be, Ti, and Zr, and the contents of the three elements of Be, Ti, and Zr are respectively: Be 0%~0.5%, Ti 0%~ 0.5%, Zr 0% ~ 0.4%. The alloy can maintain the corrosion resistance, weldability and color of the original various zinc white copper, and has higher tensile strength; because high zinc and other elements are used to replace part of copper and nickel, the cost of the invented alloy is lower than that of commercial zinc Cupronickel can replace the existing zinc-nickel-nickel copper to make various components; the alloy has good cold and hot processing performance, and can be used to produce pressure-processed products and cast products, which is suitable for industrial production.

Description

technical field [0001] The invention relates to a zinc-nickel-nickel alloy, in particular to a high-strength zinc-nickel-copper (elastic) alloy. It is especially suitable for fields such as machine manufacturing, electronic communication, chemistry, aerospace and civil industry. Background technique [0002] Zinc-nickel copper has excellent corrosion resistance, medium tensile strength, good elasticity, easy cold and hot processing, and easy welding. Therefore, it is widely used in various structural parts, springs, connectors, etc. in machine manufacturing, electronic communication, chemical, aerospace and civil industries. In recent years, it has been widely used to make glasses frame materials. With the development of modern industry, higher strength is required for zinc white copper materials. At present, domestic zinc-nickel alloys include BZn15-20, BZn18-20, BZn22-18, BZn25-18, etc., and foreign ones include CuNi12Zn24, Cu18Ni17Zn, Cu15Ni20Zn, Cu12Ni23Zn, CuNi18Zn20...
