Aluminum ingots for remelting

According to the national standard of China (GB/T 1196-2017), it should be called "aluminum ingot for remelting" and "standard aluminum" in London market. It is produced by electrolysis of alumina-cryolite. Aluminum ingot can be divided into three kinds according to its composition: remelting ingot, refining ingot and casting ingot.


a. Aluminum ingots for remelting

Execution Standard: China National Standard (GB/T 1196-2017), mainly used in the production of cast and wrought aluminium alloys.

b. Remelting

Execution Standard: China Nonferrous Metals Industry Standard (YS/T 665-2018), using high quality refined aluminium as raw material, produced by directional solidification refining method. It has low deformation resistance, high conductivity and good plasticity. It is mainly used in scientific research, electronic industry, chemical industry, manufacturing of high purity alloys, laser materials and other special applications.

c. Casting

Execution Standard: China National Standard (GB/T 8733-2016). Pure aluminium and recycled aluminium are used as raw materials, and other elements such as silicon (Si), copper (Cu), magnesium (Mg), iron (Fe) are added according to international standards or special requirements. To improve the pure aluminium in the casting, chemical and physical deficiencies of the alloy blended out. Suitable for casting and good performance of castings.
