The difference between hot rolled aluminium coils and cold rolled aluminium coils

Today let's talk about the difference between hot rolled aluminium coils and cold rolled aluminium coils. Aluminum coils are an essential material in many industries and are widely used in construction, transportation, aerospace, and electronics. These coils are available in different types, such as hot-rolled and cold-rolled aluminum coils. Both types differ in their production process, properties, and applications.

First of all, from the aluminum coil production process, aluminum coil is made of aluminum ingot melting, and then add metal elements after heating 12-15 hours, and then flow into the crystallization pool to extract impurities, cooling after the top layer of impurities to be chipped away. And then back to the furnace insulation heating, the temperature should be controlled between 450-520 degrees, insulation 12-15 hours, and then flow into the crystallization word, the following is the hot-rolled aluminum coil and cold-rolled aluminum coil different start, and hot-rolled aluminum coil is in the insulation heating temperature above the mill to start pressing, and cold-rolled aluminum coil is in the insulation heating temperature below the rolling.

So different, hot-rolled aluminum coil than cold-rolled aluminum coil, high corrosion resistance, good plasticity, fatigue resistance and other advantages. Haomei aluminum industry welcome new and old customers from all walks of life call to discuss business.

And let's talk about the applications of hot-rolled aluminum coils and the cold-rolled ones. The different properties of hot-rolled and cold-rolled aluminum coils make them suitable for use in different applications. Hot-rolled aluminum coils are commonly used in the construction industry for roofing, siding and gutters. They are also used in the transportation industry for car body panels and truck trailers. Cold-rolled aluminum coils, on the other hand, are commonly used in the aerospace industry for aircraft fuselage and wing skins. They are also used in the electronics industry for computer components and smartphone cases.
