DC 1050 Aluminum Plate

DC 1050 aluminum plate is a high-purity aluminum product with ≥99.5% aluminum content, classified under the 1xxx series of non-heat-treatable alloys. The term "DC" likely refers to Direct Chill casting, a common method for producing large aluminum ingots with controlled solidification and reduced internal stress . This alloy is prized for its excellent formability, high thermal and electrical conductivity, and corrosion resistance, making it ideal for applications requiring deep drawing, brazing, or electrical components.

Key Properties

1. Composition:

• Aluminum: ≥99.5%

• Impurities (Si, Fe, Cu, etc.): ≤0.5% total .

• The high purity ensures softness and ductility, critical for forming complex shapes like cookware or electronic parts.

Mechanical Properties (Typical for 1050-O Temper):

• Tensile Strength: 60–95 MPa

• Yield Strength: 20–40 MPa

• Elongation: 20–35% .

• The annealed (O temper) state provides maximum ductility, while tempers like H14 or H24 (cold-worked) offer higher strength but lower formability .

Physical Properties:

• Density: ~2.7 g/cm³

• Thermal Conductivity: ~220 W/m·K

• Electrical Conductivity: ~62% IACS (International Annealed Copper Standard) .

• These properties make it suitable for heat exchangers, electrical wiring, and components requiring efficient energy transfer.

• 

Applications

1. Cookware:

• Deep-drawn pots, pans, and non-stick cookware due to its formability and even heat distribution .

• The smooth surface finish of DC-cast plates reduces the risk of burrs or imperfections during shaping .

Electronics:

• Heat sinks, radiator fins, and electrical components requiring high conductivity and corrosion resistance .

• Its lightweight nature is advantageous for portable devices.

Architecture:

• Decorative trims, roofing, and cladding where corrosion resistance and aesthetic appeal are priorities .

General Fabrication:

• Sheet metal components, automotive parts, and chemical equipment due to its weldability and low reactivity .

Processing Considerations

1. Direct Chill (DC) Casting:

• This method involves pouring molten aluminum into a water-cooled mold, allowing controlled solidification from the bottom up. DC casting produces ingots with uniform microstructureand minimal segregation, enhancing formability and surface quality .

• Post-casting, the ingots are typically hot-rolled and cold-rolled to achieve the desired thickness and temper.

Forming and Fabrication:

• 1050 aluminum is highly malleable and can be easily stamped, bent, or drawn without cracking.

• It welds well using methods like MIG or TIG welding, though filler material matching the aluminum purity is recommended .

Surface Treatment:

• Anodizing is commonly applied to improve corrosion resistance and enhance aesthetics. The high purity of 1050 aluminum allows for uniform anodic coatings .

• It can also be painted, lacquered, or polished to achieve specific finishes.

Standards and Availability

• Standards:

• ASTM B209 (sheet and plate) publicationstore.com.

• EN 485 (European standard for aluminum sheet) .

• GB/T 3880 (Chinese standard) .

• Availability:

• Widely available in thicknesses ranging from 0.2 mm to 6.0 mm, with custom sizes often offered by manufacturers .

• Common suppliers include industrial metal distributors and online platforms like Alibaba .

Pricing

• The cost of DC 1050 aluminum plate is influenced by factors like thickness, temper, and order volume. As of recent market data, prices range from USD 2.10 to 4.20 per kilogramfor standard sizes . Larger quantities or specialized finishes may incur additional costs.

Comparison with Other Alloys

• 1100 Aluminum: Similar in purity (99.0%) but slightly stronger due to higher iron content.

• 3003 Aluminum: Contains manganese for improved strength, making it suitable for structural applications where formability is still critical.

• 5052 Aluminum: A magnesium-containing alloy with higher strength and better corrosion resistance, often used in marine environments.

In summary, DC 1050 aluminum plate is a versatile, cost-effective material for applications demanding high purity, formability, and thermal/electrical performance. Its combination of properties and ease of processing makes it a popular choice across industries. For specific technical requirements, consulting a supplier’s datasheet or industry standard (e.g., ASTM B209) is recommended.
