As the aluminum coil are widely used in daily life and industrial application, including automotive, pharmaceutical, electrical, and food service. Many people who have bought aluminum coil may have the basic understanding of it, but there are other aspects that aluminum coil buyer should know, here we will talk about it.
The aluminum coil has different types such as cold rolling and hot rolling. They have many difference, let me tell the difference to you one by one. About the raw materials before processing, to hot rolling aluminum coil it is aluminum ingot casting, to cold rolling aluminum coil it is large plate aluminum ingots. About the processing technology, for hot rolling aluminum coil -500 mm thick aluminum ingot casting hot rolling to 10 mm thick, then hot rolled to the requirement of the specifications of the thickness (0.4 mm), the processing load is larger. For cold rolling aluminum coil - the large plate aluminum ingots melted into liquid aluminum then processing directly to 7.0 mm aluminum sheet, cold rolled to specified thickness specification material, its processing load is small. About the material performance. The product performance of hot rolling aluminum coil is good compactness, metal crystallization, good surface, mechanical toughness and weld-ability. When it comes to cold rolling aluminum coil, the density is less than hot-rolled aluminum coil, metal crystallization is poor, the surface, mechanical toughness, weld-ability is poor than hot rolling aluminum coil. About the price. The price of hot rolling aluminum coil is generally higher than that of cold rolled aluminum coil, the price is about $100 / ton. Above is the knowledge of hot rolling and cold rolling aluminum coil, have you got it? Before purchasing any aluminum coils, you must make sure what you are using for, according to the usage and the alloy content to select the right aluminum coil. If aluminum coil buyer is still confused about this question, contact our sales manager immediately, they can give you professional guidelines and help you to save time and money!
