5052 Aluminum Tube

5052 aluminum tube is made of 5052 rust-proof aluminum alloy (Al-Mg series), containing 2.2%-2.8% magnesium and 0.15%-0.35% chromium, with excellent corrosion resistance (especially seawater and chemical media), medium strength (tensile strength 210-260MPa) and good plasticity. It can be hardened by cold working and has excellent weldability (suitable for argon arc welding). It is widely used in corrosion-resistant structural parts such as ship pipelines, automobile oil pipes, chemical transportation systems, refrigeration equipment and sports equipment. The common state is H32/H34 semi-hard state, with an outer diameter range of 6-250mm, and has both reliability and processing convenience.

5052 aluminum tube provides standard specifications with outer diameter of 8-350mm and wall thickness of 0.8-20mm, and the length can be customized to 15 meters. Made of 5052 aluminum-magnesium alloy (Mg content 2.2-2.8%), it complies with ASTM B241 standard, with outer diameter tolerance of ±0.15mm and wall thickness tolerance of ±8%. It supports multiple states such as O, H32, H34, and special specifications can be customized. The maximum single length can reach 18 meters (customization by appointment is required). The surface finish can reach Ra0.4μm, meeting the needs of high-precision fluid transmission.

The product has passed third-party testing such as SGS and BV, complies with RoHS 2.0 and REACH regulations, and can provide CPR (Construction Products Regulation) certification.

Implement three-level protection standards:

1. Inner layer: vapor phase anti-rust film (VCI) + end aluminum cap seal

2. Middle layer: customized EPS buffer module

3. Outer layer: steel belt reinforced wooden box (IPPC fumigation certification)

Sea transportation uses constant temperature containers (temperature control ±5℃), supporting trade terms such as DDP/DAP. The annual export volume exceeds 8,000 tons, and it can be reached in 20 days at major ports around the world, with a breakage rate of less than 0.1%.

Core application scenarios:

- Marine engineering: ship pipelines, seawater desalination equipment (resistant to Cl- corrosion)

- Automotive industry: new energy battery housing (specific strength up to 130MPa·cm³/g)

- Aviation equipment: hydraulic system pipelines (passed MIL-STD-810G test)

- Medical equipment: MRI components (non-magnetic properties)
