1050 Aluminum Strip

1050 aluminum strip belongs to the pure aluminum series and is very similar to 1060 aluminum strip in terms of chemical composition and mechanical properties. This high aluminum content gives 1050 aluminum strip a range of excellent properties, making it widely applicable in many fields.

With its high purity, excellent machinability, corrosion resistance, electrical conductivity, and thermal conductivity, 1050 aluminum strip is widely used in many industrial sectors. Despite its lower strength, it remains a preferred material in many applications due to its cost-effectiveness and ease of processing.

Chemical Composition and Production Process: 1050 aluminum strip contains almost no other metal elements, which makes its chemical composition relatively simple. This purity not only simplifies the production process but also makes 1050 aluminum strip relatively low-cost. Therefore, 1050 aluminum strip has a price advantage in the market, especially in applications where strength requirements are not high.
Physical and Mechanical Properties: One of the notable features of 1050 aluminum strip is its excellent plasticity, which means it has outstanding ductility and formability in various processing operations. Whether bending, stamping, or other forming processes, 1050 aluminum strip can easily adapt. Additionally, 1050 aluminum strip has superior corrosion resistance, allowing it to maintain stability even when exposed to the atmosphere or corrosive environments.
Electrical and Thermal Conductivity: Another advantage of high-purity aluminum is its excellent electrical and thermal conductivity. 1050 aluminum strip efficiently conducts electrical current and heat, making it an ideal material for electronic components, heat sinks, and conductive strips.
Strength and Heat Treatment: Although 1050 aluminum strip excels in plasticity and electrical conductivity, its mechanical strength is relatively low. This means that 1050 aluminum strip may not be as suitable for applications requiring significant mechanical stress compared to other alloyed aluminum strips. Additionally, 1050 aluminum strip cannot be strengthened through heat treatment, unlike some other aluminum alloys that can increase their strength through heat treatment. This characteristic limits its use in applications requiring high strength, but it still performs excellently in non-structural and medium-low strength applications.

Applications of 1050 Aluminum Strip

1050 Aluminum Strip for Electric Cable Armoring

1050 aluminum strip is commonly used for cable armoring due to its excellent electrical conductivity and flexibility. The soft temper (1050 O) of the 1050 aluminum strip makes it easy to process, making it an ideal choice for applications requiring good formability. Its cost-effectiveness is particularly valued, as it does not require complex processing techniques. This makes it a popular choice for armoring applications that need high conductivity and durability without incurring significant costs.

1050 O Aluminum Strip for Transformer Winding

In the transformer industry, the O temper (soft) 1050 aluminum strip is frequently used for winding dry-type transformers. The softness of 1050 O aluminum strip ensures ease of winding, while its high conductivity contributes to efficient performance of transformer windings. The typical thickness range for this application is from 0.08 to 3.0 millimeters. It is affordable and easy to manufacture, making it a practical choice for transformer manufacturers, as it does not require specialized processing and still provides reliable performance in electrical applications.

Processing of 1050 Aluminum Strip

1050 aluminum strip offers various processing options, including bending, uncoiling, welding, punching, and cutting. These processing steps ensure that 1050 aluminum strip can meet diverse industrial application requirements.

Production Process

The production process of 1050 aluminum strip begins with casting and rolling of pure aluminum or aluminum alloys into hot-rolled or cold-rolled aluminum coils. These raw materials are further processed through cold rolling mills to form aluminum strips of different thicknesses and widths. The cold rolling process gradually reduces the thickness of the aluminum coils through multiple compression steps, ensuring surface quality and flatness.

Cutting and Slitting

After cold rolling, the aluminum coils are longitudinally cut using a slitting machine according to different application needs. The slitting process cuts the wide aluminum coils into the desired width of 1050 aluminum strip. This stage is critical as it determines the final dimensions and edge quality of the 1050 aluminum strip. The slitted 1050 aluminum strip can be further processed or used directly for production, depending on the application.

Secondary Processing

After slitting, 1050 aluminum strip can undergo various secondary processing services.

Bending processes allow the 1050 aluminum strip to be bent into different shapes for manufacturing various structural components.
Uncoiling is the process of unfolding coiled aluminum strips into a flat state for further processing or use.
Welding techniques can connect aluminum strips together to form larger components or structures.
Punching can create specific shapes or sizes of holes in the 1050 aluminum strip for assembly or other functional requirements.
Cutting processes allow the 1050 aluminum strip to be trimmed to specific lengths or shapes to meet different product design needs.

Through these various processing services, 1050 aluminum strip can adapt to a wide range of applications, from construction structures to electronic devices and industrial machinery parts, showcasing excellent machinability and flexibility.

How to Prevent Oxidation of 1050 Aluminum Coils?

1050 aluminum coils have some resistance to corrosion, but they are still prone to oxidation under improper conditions, especially in water or rain. To effectively prevent oxidation of 1050 aluminum coils, the following measures can be taken:

1. Storage Environment Control

Dry: Ensure the storage environment is kept dry to prevent moisture accumulation, which helps reduce oxidation on the surface of 1050 aluminum coils.

Bright and Ventilated: Choose a bright and well-ventilated storage location to help keep the aluminum coils dry and reduce the risk of oxidation.

Non-Corrosive Atmosphere: Avoid storing aluminum coils in environments with corrosive gases, such as industrial areas or near chemicals.

2. Avoid Rain and Snow

Prevent Leakage: 1050 aluminum coils should be protected from exposure to rain and snow, especially during transportation and storage. Ensure packaging is intact to prevent water and snow infiltration.

3. Roll Oil Management

Control Moisture Content: Enhance roll oil management to ensure the moisture content is below 0.4%. This helps reduce the likelihood of surface oxidation of 1050 aluminum coils.

4. Packaging Measures

Sealed Packaging: Use sealed packaging to protect aluminum coils from direct contact with moisture and air.

Desiccant Usage: Place appropriate amounts of desiccants in each coil of aluminum to further prevent moisture ingress into the packaging.

5. Transportation Precautions

Temperature and Humidity Management: When transporting from low-temperature areas to high-temperature and high-humidity areas, do not immediately open the sealed packaging of 1050 aluminum coils to prevent condensation caused by temperature differences.

Packaging Box Conditions: Ensure the moisture content of the wooden cores and boards in the packaging boxes does not exceed 18%, and that the temperature during packaging does not exceed 45°C to prevent dampness in the packaging material or overheating of the aluminum coils.

By taking these measures, oxidation of 1050 aluminum coils can be effectively reduced, maintaining surface quality and meeting customer usage requirements.
