cold rolled aluminum and hot rolled aluminum
In the process of aluminum plate procurement, different requirements have different requirements on the type, material and process of aluminum plate, especially the distinction and recognition between cold rolled aluminum plate and hot rolled aluminum plate, which plays an important role. Aluminum plate industry, aluminum plate classification, according to the production process, aluminum plate can be divided into cold rolled aluminum plate and hot rolled aluminum plate. The difference between cold rolled aluminum sheet and hot rolled aluminum sheet is as follows:

Method 1: the production process is different: the cold rolling is made by casting and tying machine (8mm thickness), which is processed by cold rolling machine. The hot rolling is made by heating aluminum ingots (400-500mm thickness), which is rolled by hot rolling mill at high temperature.
Method 2: the supply of raw materials is different: the two are different in the supply of blank. The hot-rolled blank is cast aluminum ingots — heated — rolled into rolls for cold rolling.
Method 3: different properties: hot rolled aluminum plates have good surface quality, strong mechanical properties and ductility, and good oxidation effect. Aluminum wafers processed at the same time are generally processed by aluminum plates, and naturally affected by the performance of aluminum plates.
Method 4: different USES: cold rolled aluminum plate is mainly used in the mold, hot rolled aluminum plate is suitable for stamping and stretching aspects.
Through the above four methods, we can easily distinguish the cold rolled aluminum sheet from hot rolled aluminum sheet. The choice of aluminum sheet requires professional knowledge, and the purchase of aluminum sheet requires more professional manufacturers. If you are interested in our aluminum sheet products, we sincerely look forward to your presence and visit.

Aluminum alloys used in different areas of use are not the same treatment process, aluminum alloy after treatment will have a higher strength and hardness and elongation, cold rolling and hot rolling is a commonly used treatment process, but they have a lot of the difference.



There are four main points:
1, the production process is different: cold rolling is a casting machine into a casting roll (8mm thickness) through the cold rolling mill processing, and hot rolling is an aluminum ingot (400-500mm thickness) heating, at high temperature by Hot rolling mill rolling;
2, the raw material supply is different: the difference between the two in the blank supply is not the same, hot-rolled billet is casting aluminum ingots - heating - rolling into the volume for cold rolling, cold rolled billet is the casting and rolling - cold rolling;
3, different performance: hot-rolled aluminum plate surface quality is good, while mechanical properties and ductility performance is strong, the oxidation effect is good, while processing aluminum discs are generally processed from aluminum, naturally also received the impact of aluminum performance;
4, use different cold-rolled aluminum used for mold, hot-rolled aluminum plate for stamping stretch.
Henan Mingtai Aluminum is a collection of scientific research, processing, manufacturing as one of the large modern aluminum alloy manufacturers, with semi-continuous casting production line 6, continuous casting and rolling production line 10, 44 other large processing equipment, the annual output can reach 60 Million tons, the company's products are widely used in automobile manufacturing, transportation, packaging containers, building decoration, electronic appliances, printing and manufacturing industries, the majority of customers can rest assured that use.
