Welcome to Wuxi Yansheng Technology Co., Ltd. – Your Reliable Partner for High-Quality Aluminium Products. As a specialized manufacturer founded in 2017, we take pride in offering the 5754 H22 Aluminium Seamless Round Tube – a lightweight alloy pipe engineered for vehicle and marine equipment fabrication. With an annual export value exceeding US$50 million and a skilled team of 101-200 employees, we deliver precision and consistency for demanding applications. Our seamless tube combines excellent corrosion resistance, moderate strength, and exceptional formability, making it the ideal choice for structural components in boats, trailers, automotive parts, and marine frames.
Our factory spans 1,000-3,000 square meters and is equipped to produce tubes that meet stringent industry requirements. We ship globally from Tianjin, Shanghai, Qingdao, and Ningbo ports, serving markets across North America, Europe, Southeast Asia, and beyond. Below, we detail the technical specifications and advantages of our 5754 H22 seamless round tube.
Key Features & Technical Specifications
- Material Grade: 5754 Aluminium (Al-Mg alloy) with H22 temper (strain-hardened and partially annealed).
- Manufacturing Process: Seamless – no welding seams, ensuring uniform wall thickness and higher pressure resistance.
- Lightweight Strength: Density approximately 2.66 g/cm³, offering a high strength-to-weight ratio essential for vehicle and marine weight reduction.
- Corrosion Resistance: Excellent resistance to seawater, salt spray, and atmospheric corrosion – ideal for marine environments.
- Weldability & Formability: Good weldability using standard methods (MIG, TIG) and excellent cold formability for bending, flanging, and rolling.
- Surface Finish Options: Mill finish (standard), anodized, or customized coatings available upon request.
- Dimensional Accuracy: Tight tolerances controlled by advanced CNC equipment; diameters from 10mm to 300mm, wall thickness from 1mm to 20mm.

Why Choose Our 5754 H22 Seamless Round Tube for Your Projects? The seamless construction eliminates weak points found in welded tubes, providing better fatigue resistance under dynamic loads – critical for vehicle chassis and marine hull frames. Its lightweight nature contributes to fuel efficiency in vehicles and easier handling in marine assembly. Additionally, the H22 temper offers a balanced combination of strength and ductility, allowing for cold forming without cracking. Our tubes are suitable for further processing such as anodizing, powder coating, or machining.

Frequently Asked Questions
-
Q: What is the advantage of seamless tube over welded tube for marine use?
A: Seamless tubes have uniform wall thickness without weld seams, providing higher pressure resistance and better corrosion resistance, especially in saltwater environments. They also have superior fatigue strength. -
Q: Can you supply tubes with custom diameters and wall thicknesses?
A: Yes, we offer customization. Please provide your required dimensions, and we can produce tubes from 10mm to 300mm outer diameter and wall thickness from 1mm to 20mm. -
Q: What surface treatment options are available?
A: Standard finish is mill finish. We can also supply anodized, brushed, or painted surfaces upon request. Additional treatments like Teflon coating are available for special applications. -
Q: Is 5754 H22 suitable for welding? What welding method do you recommend?
A: Yes, 5754 has good weldability. We recommend MIG or TIG welding using appropriate filler metals (e.g., ER5356). Preheating is generally not required for thin sections. -
Q: What is the typical lead time for an order?
A: Lead time depends on quantity and customization. Standard sizes in stock can be shipped within 10-15 days. Made-to-order tubes typically require 20-30 days after confirmation. -
Q: What packaging do you use to protect tubes during shipping?
A: We use robust packaging: bundles with plastic caps, wrapped in waterproof paper, then secured in wooden crates or pallets, suitable for ocean freight. Anti-rust paper is included for marine-grade protection. -
Q: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 1 meter length) at a nominal cost plus shipping. For bulk orders, sample cost is refundable after production. -
Q: What certifications do your tubes meet?
A: Our tubes are manufactured under ISO9001 quality management system and can be supplied with mill test certificates. If you need specific standards like ASTM B210 or EN 755, we can comply upon request.
