What is Aluminum? 

Aluminum is a silvery white, soft and lightweight metal. It is the most abundant metal in the Earth's crust, but has never been found in its pure form in nature. Aluminum is widely used in everyday items such as foil, beverage cans and cooking pots. It is also used in more specialized applications such as aircraft parts and solar panels.

What is an aluminum coil?

Aluminum coil is a metal product that is subjected to flying shear after being rolled by a casting and rolling machine and processed by drawing and bending angles. Over the years, aluminum coils have grown in popularity for their lightweight, durable and corrosion-resistant properties. It is used in a variety of applications including roofing, HVAC systems and construction.

How Aluminum Coils Are Processed ?

The process of making aluminum coils is the process of processing aluminum and aluminum alloys into sheets or coils with rectangular cross-sections through processes such as smelting, ingot casting, various pre-rolling preparations, flat roll rolling, heat treatment, and finishing. The thickness of the plate is up to ~, up to 1 and extra thick plate. The width of the plate is generally 200mm, which is divided into thin plate and thick plate (5~80mm), and the roll is 2mm, and the width does not exceed 600mm. The thickness of the strip is generally not more than 5m2~10m in length.

what are the classifications of aluminum coils?

Aluminum coil is a metal product made from rolled aluminum. It is used in a variety of applications including electronics, automotive and construction. There are nine common grades of aluminum coils, namely 1000 series aluminum coils, 2000 series aluminum coils, 3000 series aluminum coils, 4000 series aluminum coils, 5000 series aluminum coils, 6000 series aluminum coils, 7000 series aluminum coils, 8000 series aluminum coils coils and 9000 series aluminum coils, each grade has its own unique physical and chemical properties.

The most common aluminum coil grade is 1100. This grade has good corrosion resistance and excellent weldability. It is also the most formable aluminum coil grade. Other popular grades include 3003, 5052, and 6061. Each grade has different physical and chemical properties that make it suitable for specific applications.

Aluminum coils can be purchased in a variety of different thicknesses. The thickness of the coil will determine the aluminum content in the final product. The thicker the coil, the more aluminum there is. Thicker coils are typically used in construction applications, while thinner coils are used in electronics or automotive applications.

Aluminum coils can be cut into various shapes and sizes using a variety of different methods. The most common method is to use a die to cut the desired shape from a roll of aluminum. Other methods include laser cutting and water jet cutting.

What is the chemical composition of aluminum coil?

The chemical composition of each grade of aluminum coil will vary.

The 1000 series aluminum sheet is also called pure aluminum sheet. Since the 1000 series aluminum coil is required to contain at least 95.0% aluminum to be considered qualified, the 1000 series belongs to the series with the most aluminum content among all series. The highest purity can reach more than 99.00%.

2000 series aluminum coils have the highest chemical element copper content, about 3-5%.

The 3000 series aluminum coil is mainly composed of manganese. The content is between 1.0-1.5.

The 4000 series aluminum coils belong to the series with higher silicon content. Usually the silicon content is between 4.5-6.0%.

5000 series aluminum coils belong to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%

6000 series aluminum coils mainly contain magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forging product.

The 7000 series aluminum coil mainly contains zinc. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a superhard aluminum alloy.

The more commonly used 8000 series aluminum coil is 8011, which belongs to other series.

The 9000 series aluminum coils belong to the spare series, and the technology is so advanced. In order to cope with the emergence of aluminum sheets containing other alloying elements, the International Aluminum Strip Federation specifically indicated that the 9000 series is the spare series. 

What is the thermal performance of aluminum coils?

Aluminum coils are widely used in many industries for their good thermal properties. The main reason is that aluminum has a high thermal conductivity, about three times that of copper. This makes it an excellent choice for heat exchangers and other applications where rapid heat transfer is required. Additionally, aluminum has a very low melting point, making it ideal for welding and other high-temperature applications.

What is the electrical performance of aluminum coils?

Aluminum coils have a wide range of electrical properties, making them ideal materials for a variety of applications. For example, aluminum coils are excellent electrical conductors with very low resistivity. This means it can be used to create circuits and carry electricity. In addition, the aluminum coil has a high melting point and is corrosion-resistant. These properties make aluminum coil ideal for electrical applications that require durability and performance.

What are the uses of aluminum coils?

Aluminum coils have many advantages that make them ideal for a wide range of applications.

- Lightweight: Aluminum is about one-third the weight of steel, so products made of aluminum coils are easier to transport and use.

- Durable: Aluminum is resistant to corrosion, so products made from aluminum coils last longer.

- Versatile: Aluminum can be painted or anodized to protect it from the elements and give it a unique look.

- Affordable: Aluminum is a cost-effective material, so products made from aluminum coils are more affordable than those made from other materials.

What are the maintenance methods of aluminum coils?

Here's how to care for aluminum coils so they last:

- Wash before first use. Even if the dishes are new, it's best to wash them with soap and water before using them. This will remove any manufacturing oil or residue that may be on the surface.

- Do not use harsh chemicals. Avoid using harsh cleaning chemicals on aluminum panels, as this can damage the finish and cause them to darken over time. Stick to mild soap and water for cleaning.

- Dry immediately after washing. Make sure to dry the aluminum panels immediately after washing, as moisture can cause them to corrode. A good way to do this is to place them on the dishwasher drain rack and let them air dry completely.

- Store in a cool, dry place. When not in use, store aluminum panels in a cool, dry place, such as a cupboard or pantry. Humidity can cause them to discolour, so it's best to keep them in a less humid environment.
