Cold rolled aluminum plate is also called cast rolled aluminum plate. The difference between cold rolled aluminum plate and hot rolled aluminum plate is from six aspects: price, billet supply, production process, performance, use and finished product.

1. Price: cold rolled aluminum plate process is simple, the price is cheaper than hot rolled aluminum plate.
2. Billet supply is different: the difference between the two is that billet supply is not the same. Hot rolling material: aluminum ingot — smelted and cast into flat ingot — milling — homogenized annealing — hot rolled into strip

Casting and rolling material: Aluminum ingot — smelting — rolled into strip by casting and rolling machine. Compared with the casting and rolling material, the production efficiency is high, but such as composition segregation, inclusion and other defects are not easy to solve, the quality is not as good as the hot rolling material.

3. The production process is different: cold rolling is a casting machine processing into the cast coil (8mm thickness) through the cold rolling machine processing, and hot rolling is aluminum plate ingot (400-500mm thickness) heating, rolling at high temperature by the hot mill;
4. Different performance: hot rolled aluminum plate surface quality, mechanical properties and ductility is strong, good oxidation effect, at the same time processing aluminum wafer is generally processed from aluminum plate, naturally also received the impact of aluminum plate performance;
5. Different uses, cold rolled aluminum plate is mainly used for mold, hot rolled aluminum plate is suitable for stamping and drawing. Cold rolled aluminum plate is also called cast rolled aluminum plate. The difference between cold rolled aluminum plate and hot rolled aluminum plate is from six aspects: price, billet supply, production process, performance, use and finished product.
6. Dinished product difference: usually cold rolled final product elongation is lower than hot rolled final product elongation. If the product is cast or hot rolled, the hot rolled product usually has a brighter surface.
