Welcome to Hemaokang Steel (Shandong) Co., Ltd. — your reliable partner for high-quality aluminum tubing solutions. Our 2024 T351 Aluminum Tube with 25mm outer diameter and 3mm wall thickness is engineered to meet the most demanding structural requirements. This product combines the excellent strength-to-weight ratio of the 2024 alloy with the T351 temper, offering superior fatigue resistance and machinability. Whether you need precision components for aerospace, automotive frames, or industrial equipment, this square-end aluminum tube delivers consistent performance and durability.
As a company with US$50 million – US$100 million annual export value and a dedicated team of 51–100 employees, we ensure every tube meets rigorous quality standards. Our production process is ISO9001 certified, guaranteeing traceability and reliability. The 2024 T351 alloy is specifically chosen for applications where high strength and low weight are critical — it is commonly used in aircraft structures, missile parts, and high-stress mechanical components. With its square end profile, this tube is easy to mount and integrate into assemblies, reducing fabrication time and costs.
Below you will find detailed specifications and features that make our product stand out in the global market. We serve customers across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. Read on to discover how this aluminum tube can enhance your project.
Key Features & Benefits
- High Strength: The 2024 alloy, heat-treated to T351 temper, provides tensile strength up to 470 MPa (68 ksi) — ideal for load-bearing structures.
- Excellent Machinability: T351 temper offers a stable, stress-relieved condition that allows precise cutting, drilling, and welding without distortion.
- Corrosion Resistance: While 2024 is not as corrosion-resistant as 6061, it can be anodized or coated for enhanced protection in harsh environments.
- Square End Profile: The square-cut ends simplify alignment and joining, saving time during assembly.
- Uniform Dimensions: Outer diameter 25mm ±0.1mm, wall thickness 3mm ±0.15mm — ensures consistent fit and performance.
- Customizable Lengths: Available in standard 6m lengths or cut to your specific requirements (upon request).

Frequently Asked Questions
Q1: What is the difference between 2024-T351 and 6061-T6 aluminum?
A: 2024-T351 offers higher strength (tensile ~470 MPa vs 310 MPa for 6061-T6) but slightly lower corrosion resistance. It is preferred for aerospace and high-stress applications where weight saving is critical. 6061 is more weldable and corrosion-resistant for general use.
Q2: Can this tube be welded?
A: Yes, 2024 aluminum can be welded using appropriate filler alloys (e.g., 4043 or 5356) and proper techniques. However, welding may reduce strength in the heat-affected zone; post-weld heat treatment may be required for full strength restoration.
Q3: What is the typical lead time for custom lengths?
A: For standard 6m lengths, we ship within 7-15 days after order confirmation. Custom cut lengths (subject to minimum order quantity) typically add 3-5 days. Please inquire for exact timing.
Q4: Do you provide certificates of compliance or mill test reports?
A: Yes, we provide both ISO9001 certification and mill test reports (MTR) for each batch, ensuring traceability of chemical composition and mechanical properties.
Q5: Is the tube surface suitable for anodizing?
A: Yes, the mill finish surface can be anodized. However, 2024 alloy does not achieve the same anodized clarity as 6061 due to copper content. We offer custom anodizing services (clear, black, or other colors) upon request.
Q6: What is the minimum order quantity (MOQ) for this tube?
A: Our MOQ is 100 kg for standard sizes. For smaller quantities, please contact us to discuss availability and pricing.
Q7: How do you pack the tubes for export?
A: Tubes are bundled with plastic caps, wrapped in waterproof paper, and secured with steel straps. We also offer wooden crates or pallets for additional protection, especially for sea freight.
Q8: Can I get a sample before placing a bulk order?
A: Yes, we provide samples (typically 300mm length) at a nominal cost, with free shipping for first-time customers. Please contact our sales team to arrange.
