Embodiment Construction

[0013] A lead-free environment-friendly zinc-nickel-nickel alloy material, which contains chemical elements and mass percentages: manganese 3.5-3.9, tin 3.8-4.1, nickel 17.5-18.9, silicon 0.6-0.9, iron 0.25-0.4, molybdenum 1.5- 1.7, Tungsten 0.3-0.5, Cobalt 0.05-0.09, Zinc 5.5-5.9, V0.9-1.2, Ta0.04-0.06, the balance is copper.

[0014] The production method of described lead-free 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 1:0.7, add pure copper into the furnace to melt, remove impurities, deoxidize, refine with a refining agent, 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 batch sequence of alloying elements put into the furnace during the alloying process is: (1)...

Abstract

The invention relates to a lead-free environment-friendly zinc white copper alloy material which contains the following chemical components in percentage by mass: 3.5-3.9% of manganese, 3.8-4.1% of tin, 17.5-18.9% of nickel, 0.6-0.9% of silicon, 0.25-0.4% of iron, 1.5-1.7% of molybdenum, 0.3-0.5% of tungsten, 0.05-0.09% of cobalt, 5.5-5.9% of zinc, 0.9-1.2% of V, 0.04-0.06% of Ta and the balance of copper. The alloy contains the silicon, manganese and Ta, and thus, has the advantages of favorable cutting characteristic, no toxicity and no harm; the alloy also contains the tungsten, V, molybdenum and cobalt, and thus, has favorable hot working property and high-temperature oxidation resistance; and the copper alloy is suitable for cutting, hot forging and polishing, and is suitable for manufacturing bearings, worm gears, gears and precision parts. When the refining agent is used for casting production, the porosity in the casting is lowered by 1-2 degrees, the oxide inclusion content is at level 2 or so, and the yield is obviously enhanced.

Description

technical field [0001] The invention relates to the field of manufacturing metal alloy materials, in particular to a lead-free and 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 can...
