Cold Rolled And Hot Rolled Aluminum Sheet Alloy
Nov 02, 2017

The difference between cold rolling and hot rolled  aluminum sheet plate is as follows:

Firstly, the production process is different. The cold rolling aluminum sheet producing process

is started from cast volume(8 mm thickness) which is made by cast machine, then rolling the cast

volume by cold rolling machine. While the hot rolling aluminum sheet is made by heating aluminum

ingots (400-500 mm thickness), and then rolling it by hot rolling machine at high temperature.

Secondly, different raw material supply. The hot rolling billet material is casting aluminum ingots though

heating and rolling, The cold rolling billet material is casting roll for cold rolling.

Thirdly, different performance. The hot rolled aluminum sheet is with good surface quality, oxidation effect,

bending performance, and strong mechanical properties and ductility. The cold rolling aluminum sheet is 

with poor mechanical properties and high hardness, so the cold rolling aluminum sheet is commonly used

for mould material, and hot rolled aluminum sheet is more suitable for deep drawing process.
