Consider the strength of supplier

When choosing a color coated aluminum coil supplier, you must first confirm the supplier's strength including factory scale, production capacity, technical process level, quality control, etc. Before confirming the order, you can understand the supplier's production capacity and equipment status by asking, visiting the factory, etc., or by asking the supplier's customers and related personnel to learn the supplier's quality level and service attitude.

Consider the stability of supply

Supply stability is also the key factor in choosing a color coated aluminum coil supplier, especially for products with long-term demand. The supplier's ability and financial strength also determine whether the supply is stable.

Consider the rationality of price

The price of color coated aluminum coils is determined according to the price of aluminum ingots. You can also conduct market surveys to understand the market price of the product and assess whether the quotation given by the supplier is reasonable.

Do you know aluminum coils? Have you heard of the aluminum coil? aluminum coil? aluminum coil? What do they mean? Why are there so many types of aluminum coils? How should I choose? This article will introduce you in detail to why there are so many models of aluminum coils.

An aluminum coil (aluminum coil) is a metal product for flying shear after rolling and bending corner processing by casting and rolling mill. Aluminum coil is a metal material widely used in electronics, packaging, construction, machinery, and other fields. At present, according to the different metal elements contained in aluminum coils, aluminum coils are roughly divided into 9 categories, namely 9 series.

Aluminum Coil Classification

Series Aluminum Coil

The series aluminum coil represents the series aluminum sheet, which is also called a pure aluminum sheet. Among all the series, the series belongs to the series with the most aluminum content. The purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. Most of the products circulating in the market are the and series. The series aluminum plate determines the minimum aluminum content of this series according to the last two Arabic numerals. For example, the last two Arabic numerals of the series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or more to be a qualified product.

Series Aluminum Coil

series aluminum coils represent 2A16 (LY16), 2A06 (LY6); series aluminum plates are characterized by high hardness, of which the copper element content is the highest, about 3-5%. series aluminum plates are aviation aluminum materials, which are not often used in conventional industries. 

Series Aluminum Coil

The representative of series aluminum coil is mainly , , 3A21. It can also be called an anti-rust aluminum plate. The series aluminum plate is made of manganese as the main component. And China's series aluminum plates are relatively outstanding in the market.

 Series Aluminum Coil

The representative of the series aluminum coil is 4A01, . This series of aluminum plates belong to the series with the higher silicon content. Usually, the silicon content is between 4.5-6.0%. series aluminum coil belongs to construction materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, and has the characteristics of heat resistance and wear resistance.

Series Aluminum Coil

The representative of series aluminum coil is , , , 5A05 aluminum coil. The series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called an aluminum-magnesium alloy. The main features are low density, high tensile strength, and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series, so it can be used for deep oxidation processing.

Series Aluminum Coil

The representative of series aluminum coil is . It mainly contains two elements of magnesium and silicon, so it concentrates the advantages of series and series is a cold-treated aluminum forged product, suitable for applications with high requirements for corrosion resistance and oxidation. Good workability, excellent interface characteristics, easy coating, and good processability. It can be used on low-pressure weapons and aircraft joints.

The general characteristics of aluminum coil: excellent interface characteristics, easy coating, high strength, good workability, and strong corrosion resistance.

Typical uses of aluminum: aircraft parts, camera parts, couplers, marine accessories and hardware, electronic accessories and joints, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical accessories, valves, and valve parts.

7000 Series Aluminum Coil

The representative of series aluminum coil is . It mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super hard aluminum alloy with good wear resistance. The aluminum plate is stress-relieved and will not be deformed or warped after processing. All super The thick aluminum plates are all ultrasonically detected, which can ensure that there are no blisters and impurities. The aluminum plate has high thermal conductivity, which can shorten the forming time and improve work efficiency. The main feature is that the hardness of is a high-hardness, high-strength aluminum alloy, which is often used in the manufacture of aircraft parts. It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance.

8000 Series Aluminum Coil

The more commonly used in series aluminum coil is . It is an aluminum plate whose main function is to make bottle caps, and it is also used in radiators, most of which are aluminum foil.

9000 Series Aluminum Coil

The series of aluminum coils belong to the spare series, and the technology is so advanced. To cope with the emergence of aluminum plates containing other alloy elements, the International Aluminum Strip Federation has indicated that the series is spare, waiting for another new variety to appear to fill the gap of the series.

The Key to Choosing Aluminum Coil

When we choose aluminum coils, it should be noted that choosing the right aluminum coil alloy directly depends on the performance and specific use scenarios. Before buying aluminum coils, you must pay attention to liquidity:

• Tensile strength

• Thermal conductivity

• Weldability

• Formability

• Corrosion resistance

For most companies that need aluminum coils as raw materials for secondary processing, the key to choosing high-quality aluminum coils is to choose a good aluminum coil supplier. My recommendation is CHAL Aluminium Corporation. CHAL is a professional supplier of aluminum coils. The price advantage of aluminum coils has always been an important reason why Chal has been welcomed by customers from all over the world.
