Product Name:

Copper Rare Earth Intermediate Alloy Cu RE Alloy

Manufacturer:

Changsha Wan特 New Materials Co., Ltd.

Property:

Blocky, vacuum-melted, available for customizing copper-re Rare Earth intermediate alloys in various ratios.

Usage:

Copper rare earth intermediate alloys feature fine crystals and dense structures, with 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 structures and its production process. The refiner contains 10-15% rare earth metal and 85-90% copper; within the rare earth metal, 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) Melting with No. 1 electrolytic copper, adding preheated rare earth metals of lanthanum, yttrium, and cerium in the specified proportions when the temperature is between 1160-1180°C. Then, degassing and slag formation are achieved by adding crushed glass and chlorides, followed by static settling. (2) Casting. The rare earth copper materials produced with this refiner feature fine crystals, dense structure, high conductivity, high softening temperature at high temperatures, good elongation, and high tensile strength.
