Plain aluminum coil refers to aluminum product that has not been specially treated, usually processed by rolling. This type of aluminum coil is usually lightweight, corrosion-resistant and has good thermal conductivity. Aluminum plain coils are widely used in many industries and daily life, and are favored for their excellent physical and chemical properties.
1. Basic characteristics of plain aluminum coil
- Lightweight: The low density of aluminum makes aluminum coils relatively light and easy to handle and process.
- Corrosion resistance: Aluminum forms a thin layer of aluminum oxide film in the air, which can resist oxidation and corrosion.
- Thermal conductivity and electrical conductivity: Aluminum has good thermal conductivity and electrical conductivity, and is suitable for electrical and heat conduction applications.
- Plasticity: Aluminum coils are easy to process and can be formed by stamping, bending, welding and other methods.
2. Production process of plain aluminium coil
The production process of ordinary aluminum coils usually includes the following steps:
- Melting: Aluminum ore is smelted into aluminum liquid.
- Casting: Aluminum liquid is cast into aluminum ingots.
- Rolling: Aluminum ingots are processed into aluminum coils through hot rolling and cold rolling processes to achieve the required thickness and width.
- Shearing and shaping: Aluminum coils can be cut into specific sizes and shapes according to customer needs.
3. Classification of aluminum plain coil
Ordinary aluminum coils can be classified according to different aluminum alloy series, such as:
- 1000 series: pure aluminum, good conductivity and strong corrosion resistance.
- 2000 series: aluminum-copper alloy, high strength but poor corrosion resistance.
- 3000 series: aluminum-manganese alloy, with good formability and corrosion resistance.
- 5000 series: aluminum-magnesium alloy, strong corrosion resistance and good welding performance.
- 6000 series: aluminum-magnesium-silicon alloy, moderate strength, suitable for heat treatment.
4. Application areas
Plain aluminum coils are widely used in many industries, including but not limited to:
- Construction: used for building materials such as roofs, walls, window frames, etc.
- Transportation: used for parts and shells of automobiles, ships, and aircraft.
- Electric: used for cables, wires and other electrical equipment.
- Packaging: used for packaging materials such as aluminum foil for food and beverages.
- Machinery manufacturing: used to manufacture various mechanical parts and equipment.
In addition, plain aluminum coils can be further processed according to different needs, such as coating to increase its corrosion resistance, wear resistance, scratch resistance and other properties, becoming coated aluminum coils. However, aluminum plain coils without any surface treatment are mainly used in construction, electronics, furniture and other fields because of their low cost and ability to meet general application requirements.
Plain aluminum coils are an important industrial material that plays an important role in modern manufacturing and construction due to their excellent properties and wide range of applications. According to specific application requirements, the specifications, thickness and alloy composition of aluminum coils can be customized to meet the requirements of different customers.
