The raw materials in our daily industry is called aluminum ingots, which is called “aluminum ingot for remelting” according to the national standard (GB/T 1196-2008). It is produced by electrolysis from alumina-cryolite.
The uses of aluminum ingots are as follows:
1. In the construction industry, due to the stability of aluminum in the air and the excellent appearance after anodization, the application of aluminum in the construction industry is more and more extensive, especially in aluminum alloy doors and windows, aluminum pipes, decorative panels, aluminum curtain walls and other applications .
2. In the transportation industry, in order to reduce the weight of their own vehicles and reduce environmental pollution caused by exhaust emissions, motorcycles, various cars, trains, subways, planes, ships and other vehicles have begun to use aluminum and aluminum alloy components and decorations in large quantities. pieces. With the continuous improvement of the hardness and strength of aluminum alloy processing materials, the proportion used in aerospace began to increase year by year.
3. In the packaging industry, various types of flexible packaging aluminum foil, aluminum cans, various bottle caps and easy-open caps, and pharmaceutical packaging are expanding the use of aluminum materials.
4. In other consumer fields, the use and use prospects of electrical appliances, household appliances (refrigerators, air conditioners), hardware, etc. are broader.
Packing: about 25Kg/ingot, packed in wooden case, net weight 1000Kg/carton, or according to customer requirements
The main models are as follows: AL99.90, AL99.85, AL99.70A, AL99.70, AL99.60, AL99.50, AL99.00
