Aluminum Alloy 1050

Aluminum Alloy 1050
Rolled aluminum products made of 1050 alloy consist of commercially pure technical aluminum with a minimum base metal content of 99.50% (Alloy family: Al-Fe-Si). It is highly recognized for its exceptional ductility, superior corrosion resistance, as well as high electrical and thermal conductivity.

Key Characteristics and Properties

Alloy 1050 (equivalent to AD0 / AD1) is a soft aluminum grade that is non-heat-treatable; its mechanical strength can only be increased via strain-hardening / cold working (deformation), denoted by tempers such as H14, H24, or H111 / H0 (fully soft annealed).

• Chemical Purity: Minimum 99.5% pure aluminum content.
• Corrosion Resistance: Outstanding global resistance to localized and atmospheric corrosion, including highly stable performance in seawater and diluted acids.
• Electrical and Thermal Conductivity: Exhibits excellent conductivity ratings, making it highly suitable for specialized electrical engineering applications.
• Ductility and Formability: Extremely high, allowing the material to easily undergo heavy bending, roll-forming, industrial stamping, and deep drawing.
• Mechanical Strength: Low mechanical yield and tensile strength properties compared to structural alloy families such as 5083 or 7075.
• Flawless Weldability: Responds exceptionally well to all standard industrial welding methods (TIG, MIG, resistance welding).

1050 Aluminum Sheets

The 1050 aluminum sheet is the most high-demand product format manufactured from this pure grade. It is divided into smooth and tread-plate (corrugated/patterned) variants.

Smooth 1050 Aluminum Sheets:

• Standard Sheet Sizes: 1000×2000 mm, 1250×2500 mm, 1500×3000 mm, 1500×4000 mm.
• Thickness Range: From 0.4 mm up to 10 mm.

Applications of Smooth 1050 Aluminum Sheets:

• Commercial Construction & Architecture: Fabrication of building exterior facade cladding panels, specialized roofing materials, heavy-duty industrial ventilation ductwork, and rainwater drainage systems.
• Industrial Manufacturing: Production of chemical processing equipment, containment vessels, industrial storage tanks, and non-toxic food-grade containers/bins.
• Electrical Engineering: Manufacturing of power distribution busbars, electrical shielding, and protective cable jacketing armor.

1050 Tread/Corrugated Aluminum Sheets

• Standard Sheet Sizes: 1000×2000 mm, 1250×2500 mm, 1500×3000 mm.
• Thickness Range: From 1.5 mm up to 4 mm.
• Pattern Types: Quintet (five-bar checker pattern), Lentil, and Stucco Embossed (“orange peel”).
• Applications of 1050 Tread Sheets: Industrial and commercial flooring: anti-slip step treads and flooring zones in public transit (buses, railcars), industrial facilities, staircases, walkways, and ramps. Also used for vehicle door-sill styling and protective wall-guard paneling.

1050 Aluminum Plates

Aluminum plates are distinguished by their higher gauge and thickness profiles compared to traditional sheet metal.

• Standard Plate Sizes: 1500×3000 mm, 1200×2400 mm.
• Thickness Range: From 10 mm up to 250 mm.
• Applications of 1050 Plates: Fabrication of heavy machinery beds, tooling base plates, large-scale containment vessels, and distribution tanks for the chemical processing industry. It is also applied in non-loaded structural engineering components where maximum chemical or atmospheric corrosion resistance is a strict parameter.

1050 Aluminum Coils

The coiled format is optimized for automated mass production, industrial stamping, and roll-forming lines.

• Thickness Range: From 0.1 mm up to 3 mm.
• Standard Coil Widths: 1000 mm, 1250 mm, 1500 mm.
• Applications of 1050 Coils: Packaging and laminates: raw material for the food industry (flexible foil, semi-rigid containers). Also specified for technical pipeline insulation jackets, architectural roofing panels, insulation sandwich panels, and mass production of small components via automated stamping lines.

1050 Aluminum Round Bars (Rods)

Solid circular profiles made of the 1050 grade are less common than those made of structural alloy series due to their low baseline yield strength, yet they are highly necessary for specific engineering requirements.

• Diameter Range: From 6 mm up to 100 mm.
• Delivery Tempers / Conditions:
  • Fully Annealed (O / H0): Offers maximum material softness and ductility.
  • Half-Hard Strain-Hardened (H14): Delivers slightly enhanced tensile metrics achieved through cold working.
• Applications of 1050 Round Bars: Precision CNC turning: fabrication of non-loaded components, electrical rivets, and custom technical fittings on automated lathes.

Critical Operational Traits of Alloy 1050 to Consider During Engineering

• High Purity & Chemical Resistance: Features exceptional resistance to environmental degradation, performing flawlessly in aggressive mediums such as marine saltwater, industrial atmospheres, and diluted organic acids. Crucially, the 1050 grade is completely immune to stress-corrosion cracking (SCC).
• Elite Ductility & Formability: Being inherently soft and highly ductile, a 1050 aluminum sheet or heavy plate easily responds to cold working operations, including heavy bending, deep drawing, industrial stamping, and contour profiling. This allows for the precise fabrication of intricate shapes with zero risk of structural cracking or material tearing.
• Flawless Weldability: Responds beautifully to all traditional industrial welding methods, such as Gas Metal Arc Welding (GMAW / MIG) and Gas Tungsten Arc Welding (GTAW / TIG), without developing solidification cracks or requiring specialized, complex filler metals.
• Superior Electrical & Thermal Conductivity: Owing to its metallurgical purity, the 1050 matrix features an elite thermal conductivity profile (approximately 130 W/m·K) and electrical conductivity rating (around 30% IACS). This makes it highly sought-after for industrial heat exchangers, cooling radiators, and power distribution busbars.
