3003 Aluminum Tube

3003 aluminum tube is a tubular material made of 3003 aluminum alloy, which is widely used for its medium strength, excellent corrosion resistance and good formability. This aluminum tube is particularly suitable for structural applications that require light weight and corrosion resistance, such as pipes in air conditioning and refrigeration systems, building drainage systems, as well as bicycle frames and some mechanical structural parts. Due to its good weldability and processing properties, 3003 aluminum tube can be easily cut, bent and connected, ensuring flexibility and reliability in a variety of industrial and daily applications. Its lightness and durability make it an indispensable material in many industries.

3003 aluminum tube provides standard specifications of outer diameter 8-250mm, wall thickness 0.5-12mm, and the length can be customized to 12 meters. Made of 3003 aluminum-manganese alloy (Mn content 1.0-1.5%), the tolerance control is strict (outer diameter ±0.1mm, wall thickness ±10%). It supports the production of various states such as O state, H12, H14, etc., and is particularly suitable for application scenarios requiring good formability and medium strength. The maximum single length can reach 18 meters (special customization).

3003 aluminum tube has excellent corrosion resistance (30% higher than pure aluminum) and a tensile strength of 145-195MPa. Its unique work hardening characteristics (elongation ≥8%) make it easy for secondary processing such as bending and flaring. With a thermal conductivity of 193W/m·K, it is an ideal choice for heat exchanger tubes. Lightweight characteristics (density 2.73g/cm³) can reduce transportation and installation costs by more than 25%.

Each aluminum tube is protected by PVC sheath at both ends and coated with anti-rust oil. Customized wooden boxes or steel frames are used for bundling packaging, and shockproof materials are used for internal spacing. Small-diameter pipes are packaged in bundles with PE wrapping film, and the weight of each bundle does not exceed 800kg. Nitrogen-filled anti-oxidation packaging can be provided for special sea transportation requirements to ensure that the product remains intact in a humid environment.

Supports a variety of processing methods:

Widely used in refrigeration system pipelines, automotive oil pipes, building structural parts and chemical equipment. Its excellent anti-corrosion performance is particularly suitable for ship pipes and chemical pipelines. In HVAC systems, 3003 aluminum tubes are widely used due to their good thermal conductivity. It is also the preferred material for solar collector brackets.

In the past five years, more than 8,000 tons of 3003 aluminum tubes have been exported to 26 countries and regions including Europe, the United States, and the Middle East. Familiar with international standards such as ASTM B491 and EN754, we can provide customers with CE, ASME and other certification support. Establish a complete international logistics network to achieve global delivery within 18 days, and the export volume has increased by 28% annually.
