Embodiment Construction
[0013] An environmentally friendly zinc-nickel-nickel alloy material, which contains chemical element components and mass percentages: nickel 11.5-12.9, cobalt 0.6-0.9, manganese 2.3-2.5, iron 0.15-0.18, bismuth 0.05-0.09, zinc 21.5-21.9, Si0.5-0.6, Sb0.03-0.05, and the balance is copper.
[0014] The production method of described environment-friendly zinc-nickel-nickel alloy material is as follows:
[0015] (1) Prepare pure copper and scrap copper as the source of copper matrix in a ratio of 1:0.6, add pure copper into the furnace to melt, remove impurities, deoxidize, use refining agent for one-time refining, add alloy components for alloying, and then add Scrap copper melting, adding refining agent for secondary refining, testing and adjusting the content of chemical elements to pass, casting, post-casting heat treatment, etc.;
[0016] (2) The order of batches of alloying elements put into the furnace during the alloying process is: (1) zinc; (2) nickel; (3) iron, cobalt...

Abstract
The invention discloses an environment-friendly zinc-copper-nickel alloy material, which comprises the following chemical components in percentage by mass: 11.5 to 12.9 percent of nickel, 0.6 to 0.9 percent of cobalt, 2.3 to 2.5 percent of manganese, 0.15 to 0.18 percent of iron, 0.05 to 0.09 percent of bismuth, 21.5 to 21.9 percent of zinc, 0.5 to 0.6 percent of Si, 0.03 to 0.05 percent of Sb and the balance of copper. The alloy material contains bismuth, Si and Sb, is easy to cut, low in cost and anticorrosive, and has high comprehensive mechanical performance; after-casting treatment temperature is reasonably controlled, waste copper is used as a raw material, so that the hardness of a core part is substantially consistent with that of the surface, and the alloy material is uniform in quality; the alloy material is applied to the production of rods and wires, and can be used for precision parts, glasses accessories, zippers, keys, optical and clock industries and the like; a refining agent is used for casting production, so that the porosity of a casting can be reduced by 1 to 2 degrees, the content of oxide inclusions is at about level 2, and the yield is remarkably increased.
Description
technical field [0001] The invention relates to the field of manufacturing metal alloy materials, in particular to an environment-friendly zinc-nickel-nickel alloy material and a preparation method thereof. Background technique [0002] Copper is widely used because of its good electrical conductivity, plasticity and corrosion resistance. Adding elements such as aluminum, nickel, manganese, tin, silicon, and lead to copper alloy can improve the performance of copper and be used in different places. At present, there are still some problems in the existing copper alloys in my country, such as the alloy contains a large number of impurity elements, poor high temperature fatigue, low high temperature strength; low hardness, poor wear resistance, large friction coefficient, short service life; poor conductivity, waste of electric energy; bending The processing performance is poor and it is easy to break; the quality is heavy and the construction is difficult; it cannot meet the ...
