Aluminum Rectangular Bar 6063-T52

The 6063-T52 rectangular aluminum bar is made from 6063 aluminum alloy through a specific heat treatment process, forming a rectangular cross-sectional aluminum bar.

The T52 temper of 6063 aluminum alloy is a heat-treatable wrought alloy optimized for extrusion. Compared to T5, it offers excellent surface finish, good corrosion resistance, and enhanced dimensional stability. The 6063-T52 rectangular bar meets ASTM B221 and AMS QQ-A-200/8 specifications and is widely used in architectural, marine, electrical, and decorative applications where a smooth surface and anodizing response are critical.

6063 T52 rectangular aluminum bars are known for their medium strength, excellent corrosion resistance, and smooth surface finish. "6063" denotes the alloy composition (primarily aluminum with added magnesium and silicon), while "T52" indicates the tempering process, which includes stress relief and artificial aging to enhance stability and mechanical properties.

Haomei Aluminum’s 6063-T52 aluminum rectangular tube is specifically designed for structural durability and lightweight performance. This extruded aluminum tube features a nominal wall thickness of 1/8 inch (0.125 inch), making it ideal for applications such as construction, automotive frames, and food service equipment. Standard lengths reach up to 72 inches (tolerance options available), and it offers both corrosion resistance and a high strength-to-weight ratio, meeting ASTM standards. We provide custom cutting services and bulk pricing, suitable for industrial projects.

Aluminum Rectangular Bar 6063-T52 Chemical Composition

The 6063 alloy is defined by The Aluminum Association (UNS A96063). "6063" consists primarily of aluminum with magnesium and silicon as the main alloying elements. The typical weight-percent ranges are:

Aluminum Rectangular Bar 6063-T52 Physical Properties

• Density: 2.69 g/cm³
• Elastic Modulus: ~69 GPa
• Thermal Conductivity: 201–218 W/m·K
• Coefficient of Thermal Expansion: 23.4 µm/m·K
• Electrical Resistivity: 30–35 nΩ·m

Temper Designation: "T52"

Definition: T52 indicates the alloy has undergone a high-temperature forming process (extrusion) followed by artificial aging treatment to achieve higher strength and hardness while maintaining tighter dimensional tolerances than T5.

Comparison with T5: T5 temper involves lower cooling and aging temperatures, whereas T52 uses a higher-temperature artificial aging cycle, resulting in slightly higher yield strength and excellent dimensional stability under thermal or load cycling.

Aluminum Rectangular Bar Mechanical Properties (T52 Temper)

For rectangular bars with thickness not exceeding 0.5 inch, typical minimum guaranteed properties are as follows:

• Ultimate Tensile Strength: ≥ 20, 000 psi (138 MPa)
• Yield Strength (0.2% offset): ≥ 14, 000 psi (96 MPa)
• Elongation at Break: ≥ 8%
• Hardness (Brinell): ~60 HB

Aluminum Rectangular Bar 6063-T52 Fabrication and Dimensional Tolerances

Manufacturing: Produced via direct extrusion in accordance with ASTM B221 and AMS QQ-A-200/8 standards; bars feature sharp 90° corners and a smooth mill finish surface.

Solid aluminum product.

Surface Finish: Matte mill finish surface, ideal for anodizing and capable of producing a uniform, bright, decorative transparent or colored coating.

Dimensional Tolerances:

Thickness and width tolerances comply with ASTM B221 standards (e.g., for widths < 2 inches, tolerance is ±0.010 inch).
