Example Embodiment

[0023] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0024] The high-manganese-copper-nickel-zinc alloy of the present invention was made into wires according to the 10 alloy component formulation examples listed in Table 1. The comparison samples were ordinary brass grade H62 alloy, ordinary zinc cupronickel grade BZn10-25 alloy and BZn15-20 alloy Manufactured wire.

[0025] The production method is as follows:

[0026] Raw material preparation and batching → smelting → continuous casting → drawing → peeling → intermediate annealing → pickling → drawing or rolling → annealing before finished product-pickling-drawing or rolling-finished product.

[0027] The production raw materials are pure copper, pure manganese, pure nickel, pure zinc, pure aluminum, iron flakes, rare earth metals, or copper-nickel-zinc master alloy, copper rare-earth master alloy, copper-manganese master alloy.

[0028] According to the prop...

Abstract

The invention discloses a method to prepare alloy of high manganese, copper, nickel and zinc and its line, stick, board and belt materials. The weight proportion of this alloy is 56-73%Cu, 0.5-2.9% Ni, 10.1-25% Mn, 0-3% Al, Fe+Re<=1%, the allowances are Zn and inevitable impurity. Sticks, lines, boards and belt materials can be produced by melting in melting furnace, processing of horizontal continuous cast and cold-working. The price of the alloy is relatively cheap and its mechanical property and corrosion resistance is better than common brass. The alloy is close to common packfong, so it can be applied in producing frames, racks and mating parts of glasses in stead of common brass H62 and packfong. It also can be used in producing slide fasteners, trimmings of dressing, artworks, structures and connectors.

Description

technical field [0001] The invention relates to a high-manganese copper-nickel-zinc alloy and a preparation method thereof for wires, rods, plates and strips. Background technique [0002] Zinc cupronickel is a copper alloy with nickel and zinc as the main additive elements. Commonly used zinc cupronickel contains 5-18% nickel, 43-72% copper, and the rest is zinc, commonly known as German silver. All countries in the world have a series of alloy grades, which are used in a wide range of fields, especially in the preparation of spectacle frames and spectacle frame accessories. It is the most used material and occupies a major position. However, since this type of alloy uses nickel as the main alloy component, and nickel is a resource-scarce element, with the rapid growth of human demand for resources, resources are becoming more and more scarce, and at the same time, the raw material cost of the alloy is becoming higher and higher. . In order to save material costs, the fra...
