Physical and chemical properties:

1. Physical properties

Appearance: The surface of 1050 aluminum coil is usually silvery white with metallic luster. Its surface is relatively smooth, which makes it very advantageous in some application scenarios with high requirements for appearance (such as decorative materials).

Density: The density of aluminum is relatively low. The density of 1050 aluminum coil is about 2.7g/cm³, which is about one-third of the density of steel. This makes it relatively light in weight and easy to transport, process and install.

Melting point: The melting point is relatively low, at 645 – 660℃. In some processes that require hot processing (such as rolling, forging, etc.), a lower melting point is conducive to reducing energy consumption and processing difficulty.

Thermal conductivity: The thermal conductivity is high, about 237W/(m·K), which means that it can conduct heat well and can play a good heat dissipation function in applications such as heat exchange equipment.

Conductivity: It has good conductivity, with a conductivity of about 35.3 – 37.7×10⁶S/m. It can be used as a good conductive material in electrical applications such as wires and cables.

Ductility: 1050 aluminum coil has excellent ductility and can be rolled into thin sheets of various thicknesses. It can also be made into aluminum products of various shapes, such as aluminum foil, aluminum wire, etc., through processes such as stretching.

Strength and hardness: The strength and hardness are relatively low, but its strength can be improved through processes such as work hardening to meet different application requirements. For example, in situations where a certain structural strength is required, it can be cold-processed to improve performance.

2. Chemical properties

Corrosion resistance: In the air, a dense aluminum oxide (Al₂O₃) protective film will naturally form on the surface of aluminum. This film can prevent oxygen and water from further contacting the internal aluminum atoms, thus having a certain degree of corrosion resistance. However, in some acidic or alkaline environments, this protective film may be destroyed, causing aluminum to corrode.

Reaction with acid and alkali: 1050 aluminum coil can react with acid, such as hydrochloric acid (HCl) to generate aluminum chloride (AlCl₃) and hydrogen (H₂); it can also react with strong alkali, such as sodium hydroxide (NaOH) to generate sodium aluminate (NaAlO₂) and hydrogen. Therefore, it is necessary to avoid contact with strong acid and alkali environment during use. Antioxidation: The antioxidation of aluminum mainly depends on the aluminum oxide protective film on the surface. At room temperature, this film can effectively prevent aluminum from being oxidized, but in high temperature environment, the aluminum oxide film may be destroyed, and appropriate protective measures need to be taken to ensure the antioxidation performance of aluminum coil.

Application:

1050 aluminum coil is widely used. In the electronics industry, due to its good conductivity and ductility, it is often used to manufacture electronic components such as capacitors and electronic foils to ensure the efficient operation of electronic equipment. In the field of construction, it can be used to make roof and wall decoration materials. Its silver-white appearance adds to the beauty of the building, and its light weight makes it easy to install. In terms of food packaging, it can be processed into aluminum foil packaging paper, which is non-toxic and has good barrier properties, extending the shelf life of food. In the transportation industry, it is used in automotive interior panels and other parts, meeting the demand for lightweighting, helping energy conservation and emission reduction, and is an indispensable material for many industries.
