Product Name:

Copper Rare Earth Intermediate Alloy Cu RE Alloy

Manufacturer:

Changsha Want New Material Co., Ltd.

Properties:

Solid, vacuum melted, available for customizing copper rare earth intermediate alloy products with various ratios.

Usage:

Copper rare earth intermediate alloys feature fine crystals and dense structures, offering high conductivity and high-temperature softening points; for instance, adding a small amount of rare earth lanthanum to pure copper can significantly enhance the copper's elongation, alloy strength, and tensile strength.

Appendix

A rare earth copper grain refiner for refining grain structure and its production process. The refiner contains 10-15% rare earth metal, 85-90% copper; among the rare earth metals, the content of lanthanum, yttrium, and cerium is 40-100%, 0-60%, and 0-60% respectively. The main characteristics of its production process are: (1) Use No. 1 electrolytic copper for smelting. When the temperature is between 1160-1180°C, add preheated rare earth metals of lanthanum, yttrium, and cerium in the above proportions. Then, degas and slag by adding crushed glass and chlorides, and let it stand. (2) Casting. The rare earth copper materials produced using this refiner exhibit small crystals, dense structure, high conductivity, high softening temperature at high temperatures, high elongation, and high tensile strength.
