Product Description

PRODUCT INTRODUCTION

Advantages of Aluminum Extruded Round Tubes

1. Optimal Strength-to-Weight Ratio  

   - Density: 2.7 g/cm³, yield strength ≥240MPa (6061-T6). Hoop structure increases bending resistance by 40% vs. solid bars.  

 

2. Superior Fluid Dynamics 

   - Mirror-finish inner surface (Ra≤0.8μm) reduces flow friction by 45%, boosting throughput 18%.  

 

3. Zero-Maintenance Corrosion Resistance  

   - Anodized layer (20μm) withstands 3000hr salt spray (ASTM B117). Service life: >30 years (land), >15 years (marine).  

4. Enhanced Thermal Transfer  

   - Thermal conductivity: 200W/(m·K). 37% larger surface area vs. square tubes improves heat dissipation by 25%.  

 

5. Fabrication Flexibility

   - Minimum cold-bending radius: 4× diameter. Compatible with flaring/swaging/TIG welding (success rate 99.2%).  

 

6. Eco-Certified Material  

   - ≥90% recycled content, 92% lower carbon footprint than primary aluminum (SGS-certified).

OUR CERTIFICATE

Q1. Material properties and tolerance control

Customer issue: Are the alloy grades, mechanical properties (tensile strength, elongation) and dimensional tolerances of the aluminum profiles in line with international standards (such as ASTM, EN)?

A:We use mainstream alloys such as 6061-T6 and 6063-T5, which comply with the ASTM B221/EN 755 standards. The tensile strength of the conventional profiles is 2 240 MPa, and the dimensional tolerances strictly follow the ISO 2768 medium precision standard. We can also provide third-party test reports (such as SGS).

Q2. Surface Treatment Process

Customer Question: How are the film thickness, corrosion resistance and color difference controlled for anodizing and powder coating?

The thickness of the anodic oxide film is 12-25 um (in line with QUALIcoAT Class Il), and the salt spray test lasts for over 1000 hours; the powder coating complies with the AAMA 2604 standard, with a color difference ΔE of s 1.5. Customization of RAL/Pantone color codes is supported.

Q3. Environmental Compliance

Customer Question: Does it comply with environmental regulations such as RoHS/REACH?

The product is completely free of harmful substances such as cadmium and lead, and the packaging materials are recyclable.

Q4. Price and MOQ Flexibility

Customer Question: Are the minimum order quantity (MOQ) and unit price competitive?

Reply: Standard profiles have a minimum order quantity of 1 ton and support small batch customization.

5. Customized Development Support

Customer Question: Can non-standard cross-sections (such as vehicle structural profiles, radiator irregular profiles) be produced?

It is equipped with an 800T-3500T extrusion machine group, capable of producing complex profiles with an outer circular section diameter of sp380mm (such as the frame of high-speed rail carriages and car luggage racks). It offers a one-stop service from mold design to extrusion and finishing, with a sample production cycle of 15 days.

6. Delivery and Logistics Assurance

Customer Question: How will the delivery schedule and international logistics be arranged?

The delivery period for standard products is 25 days, and for customized products it is 35 days. The logistics can be dispatched according to the customer's specified logistics. Thank you.
