Abstract

The invention discloses an anti-corrosion tensile copper alloy wire rod which is prepared from the following raw materials in parts by weight: 65-75 parts of copper, 10-15 parts of nickel, 5-10 partsof aluminum, 0.8-1.6 parts of zinc, 1-5 parts of magnesium, 0.5-1.3 parts of tungsten, 2.3-3.0 parts of boron, 3-8 parts of a refining agent and the balance non-metal impurities. The invention also discloses a production process of the anti-corrosion tensile copper alloy wire rod. By means of three-stage aging treatment, the copper alloy wire rod is treated by means of different tensile stresses and insulating temperatures separately to remove residual stress in the copper alloy wire rod to the maximum extent, so that the tensile strength of the copper alloy wire rod is improved. The refiningagent is prepared. When the refining agent is mixed with alloy elements, hydrogen and free oxidation slag inclusion in a molten copper alloy can be eliminated, so that the molten alloy is purifier. The molten alloy has a high adsorptive property to adsorb slag inclusion and the slag inclusion escapes quickly from a melt, so that the purity of the copper alloy is improved.

Description

technical field [0001] The invention belongs to the technical field of alloy wire preparation, in particular to a corrosion-resistant and tensile-resistant copper alloy wire and a production process thereof. Background technique [0002] Cupronickel alloy is a copper alloy with nickel as the main additive element. Its color is beautiful and mild silver white, and it has good ductility and corrosion resistance. Generally, elements such as iron and lead are generally added to the nickel-copper alloy composition in the prior art in order to enhance corrosion resistance and formability. Cupronickel is mostly used in corrosion-resistant industrial parts, and it is less suitable for cupronickel alloys and molding processes for glasses casting; [0003] Chinese invention patent CN107988526A discloses a titanium alloy spectacle frame and its preparation method. The composition of the titanium alloy is: metal A, metal B, titanium balance and unavoidable impurities; metal A is the me...
