Embodiment 1

[0021] Nickel-nickel-copper alloy preparation process comprises the following steps:

[0022] A. Primary refining: Put the prepared raw materials into the melting furnace for smelting to obtain nickel-nickel-nickel alloy melt. The nickel-nickel-nickel alloy melt contains the following mass components: Ni is 10-12%, Fe is 1.5-1.8% , Mn is 0.6-0.9%, Pb is 0-0.025%, Zn is 0-0.25%, P is 0-0.025%, C is 0.0035-0.0045%, S is 0.004-0.005%; Al is 0-1.2%; The rest is Gu;

[0023] B. Stand still: Pour the nickel-nickel-copper alloy melt obtained from primary refining into a container, then calm the nickel-nickel-copper alloy melt for at least 25 minutes, and stir at least once during the sedation to remove impurities in the nickel-nickel-copper alloy melt remove;

[0024] C. Casting: casting the sedated liquid metal melt to obtain nickel-nickel-nickel alloy.

[0025] In the above-mentioned step B, the sedation time is 25 minutes to 35 minutes; the sedation time is divided into 3 time ...

Embodiment 2

[0029] In the present embodiment, the nickel-nickel-copper alloy composition includes the following mass components: Ni is 10.30%; Fe is 1.65%; Mn is 0.79%; Pb is 0-0.02%; Zn is 0-0.2%; -0.02%; C is 0.0039%; S is 0.0045%; Al is 1.2%; the rest is Gu. The nickel-nickel-copper alloy that adopts above-mentioned nickel-nickel-nickel alloy component to make, the mechanical property of nickel-nickel-copper alloy is as follows: described Rm is 340N / mm 2 ; A is 51.5%; Rp0.2 is 130N / mm 2 ; The hardness is 108HBW.

[0030] The nickel-nickel-nickel alloy smelting process of this embodiment is similar to that of Embodiment 1, and will not be repeated herein.

Abstract

The invention belongs to the technical field of alloy materials, and particularly relates to a nickel-copper alloy and a preparation process for the same. The technical problems that in the prior art, manufacturing cost is high and the mechanical property is not enough are solved by the nickel-copper alloy and the preparation process for the same. The preparation process comprises the following steps of A, primary melting, B, standing and C, casting. Compared with the prior art, the nickel-copper alloy and the preparation process for the same have the advantages that the content of nickel is low, the material cost can be greatly reduced, and the cost is reduced; the mechanical property is good, and balance between the material cost and the mechanical property is achieved.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and in particular relates to a nickel-nickel-nickel alloy and a preparation process thereof. Background technique [0002] Nickel-nickel copper is a copper-based alloy with nickel as the main additive element. It is silvery white and has metallic luster, hence the name nickel-nickel-nickel. Copper and nickel can be infinitely dissolved in each other to form a continuous solid solution, that is, regardless of the ratio of each other, it is always an α-single-phase alloy. When nickel is melted into red copper and the content exceeds 16%, the color of the resulting alloy becomes as white as silver, and the higher the nickel content, the whiter the color. The nickel content in nickel cupronickel is generally 25%. Pure copper plus nickel can significantly improve strength, corrosion resistance, hardness, electrical resistance and pyroelectricity, and reduce the temperature coefficient of res...
