  • 3003-H14 Aluminum Construction
  • ASTM B209 Certified
  • 22,000 PSI Tensile Strength
  • Excellent Weldability & Formability
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

3003-H14 aluminum is a commercially pure aluminum alloy with manganese added for increased strength. The H14 temper indicates it is strain-hardened and partially annealed, providing a balance of strength and formability. This non-heat-treatable plate meets ASTM B209 standards and is valued for its excellent corrosion resistance and weldability, making it one of the most widely used general-purpose aluminum alloys.

The 0.188" thickness classifies this as a medium plate, making it suitable for applications requiring more rigidity than thin sheets. Common uses include structural panels, machine guards, vehicle body components, architectural cladding, and fabricated parts where moderate strength and excellent formability are essential.

Specifications

  • Material: 3003-H14 Aluminum
  • Standards: ASTM B209
  • Strength/Tensile: 22,000 PSI
  • Dimensions: 0.188" Thickness x 48" Width x 120" Length
  • Finish: H14 Temper (Strain Hardened, Half-Hard)
  • Certifications: Mill Test Report (MTR) Available

Applications

  • HVAC: Ductwork and fan blades - for its excellent formability and atmospheric corrosion resistance.
  • Chemical Equipment: Storage tanks and containers - due to high resistance to chemical corrosion.
  • General Fabrication: Machine guards and stamped parts - because it is easily formed, welded, and finished.
  • Automotive: Radiator parts and fuel tanks - valued for its workability and lightweight properties.

Target Users

Fabricators, sheet metal workers, welders, and engineers rely on 3003-H14 aluminum plate for its reliability and ease of use in industrial and architectural applications throughout the Los Angeles area.

Finish Options

This product comes standard with a mill finish, which may have some surface imperfections from the manufacturing process. For specific project requirements, other finishes such as anodized, painted, or polished may be available via special order. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Plate is measured by its Thickness (T), Width (W), and Length (L). Use a tape measure for width and length, and calipers for an accurate thickness reading.

Example: To order this plate, specify "3003 Aluminum Plate, 0.188" x 48" x 120""
