Product Introduction

Aluminum coil can be produced from aluminum ingots or other forms of raw aluminum (called cold rolling or direct cast) or from a smelting process directly through rolling (called continuous cast). These sheets of rolled aluminum are then rolled up, or coiled, around a core. These coils are densely packed, making them easier to ship and store when compared to aluminum in sheet form. Coil is used to manufacture an almost unlimited range of components used in an extensive number of industries.

Pure aluminum is too soft for most manufacturing applications. Therefore, most aluminum coil is manufactured and supplied as an alloy. These alloys composed of at least two or more elements of which at least one is aluminum. Aluminum alloys for sheet products are identified by a four digit numerical system which is administered by the Aluminum Association. When alloyed with other metals, aluminum’s mechanical and other properties can be tailored to meet specific requirements for strength, formability, and other properties.

Aluminum coil is available in variable lengths, widths and thicknesses, also referred to as “gauge”. The exact dimensions are determined by the size of the components being made, and the manufacturing process that is used to produce them. Several surface finishes are available including mill, matte and bright. Selection will depend on the use and desired look of the finished part.

Advantages of Aluminum Coil

1.Lightweight and high strength: Aluminum coil has a lower density, which makes it much lighter than traditional metal materials such as iron and copper in the same volume. However, through reasonable alloying design and heat treatment process, aluminum coils can exhibit excellent mechanical properties and meet the needs of various structural parts and load-bearing components. This lightweight and high-strength characteristic gives aluminum coils significant advantages in aerospace, transportation and other fields.

2.Good corrosion resistance: A dense aluminum oxide film is easily formed on the surface of the aluminum coil. This film can effectively isolate air and moisture and prevent further oxidation and corrosion of the aluminum coil. Therefore, aluminum coils can still maintain good stability and durability in harsh environments such as moisture and corrosiveness. This characteristic makes aluminum coils widely used in construction, electronic appliances and other fields.

3.Excellent processing performance: Aluminum coils have good ductility and plasticity, and are easy to perform various processing operations such as cutting, stamping, bending, and welding. This allows aluminum coils to flexibly respond to various complex shapes and sizes during the manufacturing process, reducing processing difficulty and cost. At the same time, the surface of the aluminum coil can also be painted with secondary coatings, such as wood grain, stone grain, etc., which has rich decorative properties.

4.Good thermal and electrical conductivity: Aluminum coil is a good conductor of heat and has good thermal conductivity. This characteristic makes aluminum coils widely used in cooling equipment, heat exchangers and other fields. At the same time, aluminum coils are also good conductors of electricity and can meet the conductive needs of electrical equipment.

5.Environmentally friendly and recyclable: Aluminum coil is a recyclable metal material with a simple recycling process and low energy consumption. By recycling and reusing aluminum coils, resource consumption and environmental pollution can be significantly reduced, which is in line with the concept of sustainable development.

6.Other advantages:

• No low-temperature brittleness: Aluminum coils can still maintain good toughness in low-temperature environments and are not prone to brittle fracture.

• Sound absorption: Aluminum coils have certain sound absorption properties and can be used to make sound-absorbing materials to reduce noise pollution.

• Nuclear radiation resistance: Aluminum coils have certain resistance to nuclear radiation and can be used in fields such as the nuclear industry.

• Strong seismic resistance: Aluminum coils have good seismic performance, which provides a strong guarantee for safety.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications of Aluminum Coil

1. Construction field

• Decorative materials: Aluminum coils are often used as decorative materials in the construction field, such as curtain walls, ceilings, window frames, etc. Its beautiful appearance and good fire resistance and weather resistance make it an ideal building decoration material.

• Building materials: Due to the lightweight properties of aluminum coils, it can reduce the weight of the building and improve the seismic performance of the building. Therefore, it is often used to make building materials such as roofs and wall panels, which helps improve the overall performance and service life of the building.

2. Electronic industry

• Electronic device casing: Aluminum coils have good corrosion resistance and thermal conductivity, so they are often used to manufacture casings for electronic devices, such as laptops, mobile phones, tablets, etc. These cases are not only beautiful and elegant, but also effectively protect electronic devices from damage from the external environment.

• Electronic components: Aluminum coils are also widely used in the manufacturing of electronic components, such as radiators, battery casings, etc. Its good thermal conductivity helps dissipate heat from electronic components and maintain their normal operating temperature, thus improving the stability and service life of electronic equipment.

3. Packaging field

• Food packaging: Aluminum coils have good sealing properties and antioxidant properties, which can effectively protect the freshness and quality of food. Therefore, it is often used to make packaging materials such as cans and food packaging boxes.

• Pharmaceutical packaging: Similarly, aluminum coils are also suitable for pharmaceutical packaging. Its sealing and antioxidant properties help maintain the stability and effectiveness of medicines, thereby ensuring patient safety.

4. Other fields

• Automobile manufacturing: Aluminum coils are also used in automobile manufacturing, such as automobile fuel tanks, body panels, etc. Its lightweight characteristics and good corrosion resistance help reduce the weight and fuel consumption of cars, and improve the fuel economy and environmental performance of cars.

• Machinery manufacturing: In the field of machine manufacturing, aluminum coils are often used to make mechanical parts and mold materials. Its good plasticity and processing properties enable aluminum coils to meet the needs of various complex shapes and sizes.

• Chemical industry: Aluminum coils are also used in the chemical industry, such as in the production of chemical equipment such as reactors and storage tanks. Its corrosion resistance helps extend the service life of equipment and improve production efficiency.
