1050 Aluminum Disc Circle

What is 1050 Aluminum Disc

1050 aluminum disc is a circular sheet material made from 1050 aluminum alloy (commercially pure aluminum), known for its high purity, excellent processing performance, and wide range of applications.

With high purity, easy formability, and stable comprehensive performance, 1050 aluminum disc is a common material used in electronics, packaging, construction, and other fields. When selecting, it's important to match the temper (H12/H24, etc.) with the application scenario (conductivity/corrosion resistance/formability), and to consider 1060 alloy first for high-conductivity requirements.

This alloy offers excellent corrosion resistance, high thermal and electrical conductivity, superior deep drawing ability, and good formability, making it suitable for various applications.

1050 aluminum disc is renowned for its extremely high aluminum content and strong market demand, making it one of the most widely used aluminum alloys. Additionally, its relatively affordable price makes it a cost-effective choice for many applications.

1050 Aluminum Disc Circle

1050 aluminum disc also has excellent cold working formability, with an elongation rate of 35% to 38%, offering excellent stability and ductility. Due to their softness, these discs are especially suitable for applications requiring high plasticity, making them ideal materials for manufacturing various products.

Haomei Aluminum is committed to providing the highest quality products. Our 1050 aluminum discs are subjected to strict quality control to ensure they meet the highest standards. We offer products in various sizes and thicknesses, ensuring the perfect circular product for your specific needs.

Haomei 1050 Aluminum Disc Quality Control System

As a professional aluminum circle manufacturer, Haomei always adheres to the principle of "quality first". From raw materials to finished products, every process is strictly controlled to ensure that each 1050 aluminum disc meets the high standards of our customers.

Chemical Composition Control: Ensuring Material Purity from the Source

We understand that chemical composition is fundamental to product performance. Therefore, strict full-process control is implemented for 1050 aluminum disc composition:

Raw Material Inspection: Each batch of aluminum ingots undergoes spectroscopic analysis to verify that the chemical composition complies with GB/T 3190 standards or customer-specified standards.

Smelting Process Monitoring: Sampling and analysis points are set during smelting to monitor the composition changes of molten aluminum in real time. The alloy ratio is adjusted according to the results to ensure precise and stable composition.

Finished Product Sampling: Before delivery, finished products are batch-sampled and tested with direct-reading spectrometers to ensure consistency and traceability of the final product's chemical composition.

Dimensional Accuracy Control: High-Precision Equipment Ensures Geometric Accuracy

Dimensional accuracy directly affects the quality of customers' subsequent processing. We ensure dimensional consistency through advanced equipment and rigorous inspection:

Advanced Equipment Support: We have introduced high-precision casting-rolling lines, cold rolling mills, and stamping machines to ensure that both the original coil and the aluminum discs meet extreme tolerance requirements in thickness and diameter.

Die Management System: A die maintenance plan is established, including regular calibration and replacement, to ensure consistent disc dimensions, free from burrs and eccentricity.

Online Inspection Technology: Key production stations are equipped with laser thickness gauges and CCD optical detectors for real-time data feedback and automatic warning.

Finished Product Dimensional Inspection: A professional quality inspection team uses micrometers, calipers, and other precision instruments to conduct sampling inspection, ensuring that diameter and thickness deviations meet customer standards (e.g., within ±0.05mm).

Mechanical Properties Control: Ensuring Processability and Performance

To meet customer requirements for stamping, drawing, and other subsequent processing, we focus on controlling the mechanical properties of 1050 aluminum discs:

Rolling Process Control: Multiple rolling passes and a well-designed reduction rate are used to adjust work hardening levels, ensuring material uniformity and ductility.

Heat Treatment Process Optimization: A continuous annealing furnace is used to precisely control temperature and holding time, ensuring the ideal soft O-temper microstructure.

Grain Refinement Control: Cooling rates are strictly controlled during aluminum casting and heat treatment to suppress coarse grain formation and enhance overall performance.

Mechanical Property Testing: Each batch of finished products undergoes tensile strength, yield strength, and elongation tests. Data is archived and available for customer traceability.

Surface Quality Control: Ensuring Appearance and Post-Processing Compatibility

We place great importance on the surface condition of 1050 aluminum discs, which affects not only aesthetics but also subsequent surface treatments and processing:

Substrate Surface Control: High-quality aluminum sheets with clean surfaces, free of indentations and bubbles, are selected as raw materials for stamping.

Clean Production Environment: We implement clean production throughout. Equipment is maintained daily, and oil stains, metal chips, and other contaminants are eliminated in the production area.

Pre-Treatment Process: According to customer requirements, surface cleaning, degreasing, and passivation are conducted to enhance adhesion and corrosion resistance.

Strict Visual Inspection: A combination of manual visual inspection and optical detection is used to identify defects such as oxidation spots, scratches, and surface unevenness, ensuring flawless appearance.

Every 1050 aluminum disc delivered by Haomei Aluminum is rigorously screened through our quality control system, meeting both industry standards and special customer requirements. We do not just deliver products—we deliver a commitment and responsibility to quality.

1050 Aluminum Disc Circle Processing Characteristics

Mechanical Properties

After treatment in states such as H12 or H14, the material possesses a balance of strength and ductility, making it suitable for stamping, spinning, and other processing needs, and is resistant to cracking during processing.

Surface Treatment

Some products have a film coating or polished surface treatment, making them suitable for applications that require high surface smoothness, such as heat dissipation fans and traffic signs.

While 1050 aluminum discs offer many advantages, their mechanical strength is lower compared to other aluminum alloys. Therefore, for applications requiring higher strength, other alloys like 3003 or 5005 may be more suitable.

1050 aluminum discs are versatile components, widely used in multiple industries due to their excellent performance (including high purity, formability, and electrical conductivity).
