Hot rolled aluminum circle is a round thin sheet of aluminum produced by hot rolling process. It has good ductility and plasticity, which facilitates subsequent processing and molding. Hot rolled aluminium circle is widely used in a variety of industrial and manufacturing applications, especially in the kitchenware, lighting, electronics and packaging industries.
The main aluminum alloys commonly used for hot rolled aluminum circle include:
- 1000 series: such as 1050, 1060, 1070, 1100 etc. It has good ductility and corrosion resistance, and is suitable for applications requiring high electrical and thermal conductivity.
- 3000 series: such as 3003, 3004, 3105, etc., with good formability and weldability, commonly used in the manufacture of pots and pans and other kitchen utensils.
- 5000 series: such as 5052, 5083, etc., with high strength and corrosion resistance, suitable for marine environments or applications requiring strength.
- 6000 series: such as 6061, etc., with good mechanical properties and welding performance, suitable for structural parts and other applications requiring strength.
In terms of specifications, the thickness and diameter of hot rolled aluminum circles can be customized according to demand, with common thicknesses ranging from 0.5mm to 10mm and diameters from a few centimeters to several meters.
The production process of hot rolled aluminum discs generally includes the following steps:
- Ingot melting: melting the raw aluminum alloy to form aluminum water.
- Casting: Casting the aluminum water into aluminum ingots.
- Heating: Heating the aluminum billet or ingot above the recrystallization temperature of the metal to improve its plasticity and ductility for subsequent rolling.
- Hot Rolling: Rolling of aluminum billets or ingots under high temperature conditions using a rolling mill, rolling into thin sheets, the process requires temperature and rolling speed control.
- Annealing: the hot rolled aluminum sheets are annealed to eliminate their internal stress and improve their performance.
- Shearing: Shear the rolled aluminum sheet into the required round shape.
- Surface treatment: Surface treatment, such as cleaning and coating, is carried out as required.
- Inspection and Packaging: Quality inspection of the finished products, packaging after passing.
Hot rolled aluminum circle has the following advantages:
- Excellent surface quality: after hot rolling and annealing treatment, the surface of aluminum circle is flat, smooth and without obvious defects.
- Excellent mechanical properties: hot rolled aluminum circle usually has high strength and good ductility.
- Lightweight: Aluminum has a lower density, which can reduce the overall weight of the product.
- Corrosion resistance: the oxide film formed on the surface of aluminum alloy gives it good corrosion resistance and can extend its service life.
- Thermal and electrical conductivity: some aluminum alloys have excellent thermal and electrical conductivity, suitable for electronic products.
- E-asy processing: aluminum circle is easy to carry out subsequent processing, such as stamping, cutting, etc.
Hot rolled aluminium circle has a wide range of applications, including:
- Kitchenware: such as pans, frying pans, etc.
- Packaging materials: such as aluminum foil, aluminum cans, etc.
- Electronic products: such as heat sinks, lamps and lanterns shells, etc.
- Transportation: road signage, etc.
In short, hot rolled aluminum circle has become an indispensable and important material in industrial production due to its excellent performance and diverse applications.
