2000 Series Aluminum Coil Overview:
What are 2000 series aluminum alloy coil?
2000 series alloy aluminum coil on behalf of 2014 aluminum coil, 2024 aluminum coil, 2A16 (LY16) 2A06 (LY6), 2000 series aluminum coil is characterized by high hardness, which is the highest content of the original genus of copper, about 3-5%. 2000 series aluminum coil belongs to aviation aluminum, currently not often used in the conventional industry.
What does the 2 series aluminum coil metal contain?
2000 series aluminum grades contain 0.7-6.8% copper and small amounts of silicon, manganese, magnesium and other elements. Copper is the alloying element of these grades, which imparts extra strength and hardness, improving their machinability. The high strength of these grades is maintained over a wide temperature range.
The 2000 series are heat treatable aluminum grades. Precipitation hardening can be performed to increase its strength. The precipitation of the intermetallic compound Al2Cu during the heat treatment increases the hardness of the alloy. However, intermetallic compounds can make these grades difficult to weld. Some 2000 series grades are not suitable for arc welding because they are prone to thermal cracking and stress corrosion cracking.

How is aluminum coil produced?
Aluminum coils need to go through a series of processing steps before use to obtain thinner aluminum coils.
1. Solvent. First, the raw material, the aluminum ingot, needs to be melted and alloyed, and after electromagnetic stirring, the furnace is guided to the holding furnace.
2. Over the mold. Through a set of molds, adjust the corresponding width.
3. Casting. 6-8mm thick cast-rolled aluminum coils are made by casting and rolling mills.
4. Cool. The casted aluminum coil needs to be air-cooled and rolled to the corresponding thickness in a cold rolling mill.
5. Annealing. The cold-rolled aluminum coil has a certain degree of rigidity. It is annealed to reach the corresponding state, and then pulled and bent to straighten the shape. After inspection, it is packaged into a finished aluminum coil.
6. Painted. Aluminum coils can be processed into different types, transferred to the color-coated aluminum coil production line, and produced into color-coated aluminum coils after unwinding, pre-treatment, chroming, and coating coating winding.
