6063-T5 Aluminum Alloy 

Al-Mg-Si alloy for industrial frames, enclosures and architectural profiles.

Aikerly supplies standard and custom 6063-T5 aluminum profiles, subject to technical and manufacturing review.

Overview

6063 is a heat-treatable Al-Mg-Si alloy. T5 indicates cooling from an elevated-temperature shaping process followed by artificial aging. It offers good extrudability, corrosion resistance and anodizing performance, with moderate strength.

Available Forms

Standard and custom profiles, including angles, channels, tees, rails, frames and heat sinks. Options include cut-to-length supply, anodizing, powder coating, painting, drilling, tapping and CNC machining, subject to drawing review.

Custom profiles require assessment of cross-section, wall thickness, tolerances, tooling and quantity.

Chemical Composition

Typical limits under ASTM B221 / EN 573-3; confirm the applicable standard and mill certificate.

Mg 0.45–0.90%; 

Si 0.20–0.60%;

 Fe ≤ 0.35%; 

Cu, Mn, Cr, Zn and Ti each ≤ 0.10%; 

other elements each ≤ 0.05%, total ≤ 0.15%; Al balance.

Key Properties

Typical values, subject to profile dimensions and applicable standard:

• Tensile strength: approximately 150–200 MPa

• Yield strength: approximately 110–170 MPa

• Elongation: approximately 6–12%

• Good extrudability, atmospheric corrosion resistance and anodizing response

• Moderate strength compared with 6061-T6

Confirm specified minimum properties and acceptance criteria before ordering.

International Standards

Common references include GB/T 6892, GB/T 5237, EN 755 and ASTM B221. Applicability depends on product type and intended use. Specify the governing standard, temper, dimensions and acceptance requirements in the purchase order.

Processing Considerations

Extrusion feasibility depends on profile geometry, wall thickness, tooling and quantity. Machining requires dimensional and distortion review. Anodizing and powder coating depend on surface quality and pretreatment. Welding may reduce strength in the heat-affected zone.

Typical Applications

Industrial frames, machine guards, automation structures, heat sinks, electronics enclosures, doors, windows, architectural trims and lightweight rails.

Grade Selection

6063-T5 suits general-purpose profiles and surface-finish applications. Consider 6061-T6 where higher strength is required, subject to extrusion feasibility. For formed sheet or plate, consider 5052-H32 where corrosion resistance and formability are priorities. Substitution requires approval.
