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 present invention relates to one kind of high strength German silver alloy comprising Ni 13-17 wt%, Zn 28-45 wt%, Be 0-0.5 wt%, Ti 0-0.5 wt%, Zr 0-0.4 wt% and Cu for the rest, with Cu+Zn+Ni content being not lower than 99.5 %. The high strength German silver alloy has high corrosion resistance, weldability and color similar to that of other German silver, even high tensile strength, relatively low cost, and excellent cold and hot working property. It may be applied to replace available German silver in making different elements, and may be also applied in making pressure worked product and cast product.

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...
