1050 Aluminum Coil

1050 aluminum coil belongs to the industrial pure aluminum series. According to international naming rules, its aluminum content must be ≥99.5% (the last two digits "50" indicate purity requirements). The main impurities are Fe and Si, while other trace elements such as Cu, Mg, and Mn are present in extremely low amounts.

1050 aluminum coil is a commercially pure forged aluminum alloy in the 1xxx series. It is widely used in industries that require corrosion resistance, electrical and thermal conductivity, high reflectivity, and formability, although its mechanical strength is relatively low compared to alloy grades.

Due to its high-purity aluminum base, low cost, and comprehensive performance, 1050 aluminum coil is extensively used in printing, electronics, and construction industries. Its various tempers (such as H18 and H24) can meet diverse requirements, ranging from high-strength demands to complex forming applications.

Haomei Aluminum specializes in the production of 1050 aluminum coil, aluminum sheet, and aluminum strip. The material is stable, with electrical conductivity reaching up to 99%, making it suitable for industrial conductivity applications, architectural decoration, transportation equipment, and more. We have regular specifications in stock and support customized processing (thickness and width can be flexibly adjusted). With ample inventory, we provide a one-stop aluminum material solution to meet the needs of both domestic and international customers.

1050 Aluminum Coil Characteristics

Chemical Composition: Mainly composed of aluminum (≥99.5%), with extremely low alloy element content. This composition ensures high purity, contributing to excellent electrical conductivity and corrosion resistance.
Physical Properties: Density is approximately 2.7g/cm³, and the melting point ranges from 646–660°C. Its high thermal conductivity makes it an ideal choice for applications requiring efficient heat dissipation.
Mechanical Properties: Due to its high purity, 1050 aluminum exhibits excellent ductility and machinability, but its mechanical strength is relatively low. Unlike metals with higher alloy content, it cannot be strengthened by heat treatment but instead relies on cold working (such as strain hardening) to improve its strength when necessary.
Surface Treatment: Its highly reflective surface benefits decorative and functional applications, such as light reflectors and building flashings.

1050 Aluminum Coil Tempers

1050 H18 Temper

Deeply cold-work hardened, high tensile strength (suitable for decorative materials requiring structural strength, small industrial components);
Limited machinability, only suitable for simple stamping or bending.

1050 H24 Temper

Moderately work-hardened, moderate strength, combined with good electrical conductivity and corrosion resistance;
Better machinability than H18, capable of forming complex curves (such as decorative trims, casings).

1050 Aluminum Coil Manufacturing and Processing

Cold workability: Can be strengthened by cold working (e.g., rolling, drawing) but cannot be heat-treated.
Temper options: Includes O (soft), H12–H19 (various hardness levels), and H22–H28 (partially annealed).

Processing response:

Well-suited for cold forming, welding (gas, arc, resistance), and soldering.
Due to its softness, machinability is relatively poor.

1050 Aluminum Coil Typical Applications

Printing industry: CTP plate base, PS plate base (requiring high flatness and ultra-thin specifications);
Electronics and electrical: Capacitor casings, conductive connectors (utilizing high electrical conductivity);
Architectural decoration: Aluminum composite panels, lighting materials, outdoor advertising frames (suitable for corrosion resistance);
Industrial components: Heat sinks, nameplates, chemical containers (requiring formability and corrosion resistance).
Electrical industry: Heat sinks, cable sheathing (high electrical conductivity).
Chemical industry: Storage tanks, containers (corrosion resistance).
Construction: Waterproof panels, roofing, and decorative finishes (compatible with anodizing).
Consumer goods: Battery foil, food packaging, and light reflectors.

1050 Aluminum Coil Advantages and Limitations

Advantages: Cost-effective, lightweight, corrosion-resistant, high formability.
Limitations: Lower strength compared to alloys like 3003 or 5052; not suitable for high-stress applications.
