Example Embodiment

[0007] In various melted conventional copper or copper alloy solutions, add a small amount of copper-niobium master alloy or niobium metal to prepare niobium microalloyed copper liquid, and produce various plates, strips and foils according to known forming methods. , Tubes, rods, wires of copper and copper alloy materials.

[0008] The following takes the production of a φ9.25*0.38mm niobium microalloyed phosphorous deoxidized copper smooth surface tube as an example to illustrate the implementation process of the present invention.

[0009] Put the cathode copper plate into the power frequency cored melting furnace, and melt it into a copper liquid under the protection of the drying charcoal. The 2Kg phosphor copper alloy (CuP 14 ) Is added to 1000Kg of copper liquid for deoxidation to obtain a low-oxygen copper liquid. After the deoxidation is completed, a copper-niobium master alloy with a weight of 2Kg is added to this copper liquid three times to prepare a niobium microalloy...

Abstract

The invention discloses a niobium microalloying copper and copper alloy material, which is characterized by the following: distributing 0.001-0.03% niobium element of even nanometer particle in the copper or copper alloy base; improving welding and softening property without damaging conductivity and heat conductivity.

Description

Technical field: [0001] The invention relates to a non-ferrous metal alloy material, specifically niobium microalloyed copper and copper alloy material. Background technique: [0002] With the increasingly fierce competition in the field of copper and copper alloys worldwide, the requirements for the quality and comprehensive performance of copper and copper alloys are getting higher and higher. The direction of corrosion is developing, which requires copper and copper alloy materials to increase their strength while improving their ductility. At the same time, welding is required in the process of using these materials for product manufacturing, and the grains of the material at the welding site are easily enlarged, resulting in a significant decrease in the strength of the material in the welding area, causing various serious quality accidents. In recent years, metal niobium has been successfully applied in the field of ferrous metallurgy (mainly steel materials) as an al...
