Popular aluminum alloys for tubes and pipes

Choosing the right alloy is the first decision in any aluminum tube project. Strength, corrosion resistance, weldability and surface finish pull in different directions, so the table below compares every tube alloy Chalco stocks side by side.

Values are typical for extruded or drawn tube and are given for comparison only — ASTM B210 / B221 / B241 or EN 754 / 755 minimums govern the material we supply. Mill test certificates are issued with every shipment.

Still deciding between two alloys? These comparisons go deeper: 6061 vs 6063, 6061 vs 7075, 5052 vs 6061, 6061 vs 6082, 2024 vs 7075. Not sure what T6, T5 or H32 means? See our guide to aluminum alloy tempers.

Aluminum tube fabrication and finishing services

Most customers do not need a full mill length. Chalco cuts, bends, machines and finishes tube in house before it ships, so the material arrives ready to install or assemble.

• Cut to length — single cuts from 50mm up to 13m, tolerance ±0.5mm, saw-cut or deburred ends. Minimum order is one piece.
• Mandrel bending — bent aluminum tubing to your CAD radii, with wall thinning controlled below 15%.
• CNC machining and threading — internal and external threads, cross-holes, slots, flaring, swaging and end forming. See our CNC aluminum machining capability.
• Welding and brazing — TIG, MIG and vacuum brazing for assemblies and manifolds. Read our guide to welding 6061 aluminum.
• Laser and saw cutting — profiled cuts and copes; see laser cutting aluminum for parameters.
• Surface finishing — anodizing in clear, black, blue and custom colours, powder coating, polishing and brushing. Background on the process: anodizing aluminum and aluminum surface treatment.

Three main factors of aluminum tube bending

1. Formability

Some aluminum alloys, such as 3000, 5000 and 6000 series, have higher formability than other aluminum alloys, making them good bending materials.

2. High precision

Like other metals, aluminum will appear "work hardening" during bending. This means that it will become stronger and stronger when formed. However, if ratio of radius to pipe thickness is too small, the material will be over machined and more likely to lose efficacy.

3. Rate of elongation, flexibility

Percentage of elongation is a way of describing the difference between the yield strength of a metal and its ultimate tensile strength. Yield strength is the point at which an aluminum alloy can be bent and no longer restored to its original shape. The greater the difference between these strengths, the better the formability of the alloy.

Aluminum tubes have excellent bending properties and are suitable for various complex pipeline design and installation requirements.

Brazing and welding of aluminum pipe

Low temperature operation: The brazing operation temperature of aluminum tubes is low, which reduces the thermal impact on the material.

Strong connection: The aluminum tube joints after brazing have high strength and durability, suitable for long-term use.

High strength: The aluminum tube after welding maintains high strength and durability, suitable for various applications with high strength requirements.

The difference between seamless aluminum tubes and seamed aluminum tubes

From the production point of view: seamless aluminum tubes are produced by reverse extrusion machines, the processing technology is relatively complex and the cost is high. Seamed aluminum tubes are extruded by forward extrusion machines, which are fast to produce and low in cost.

From the surface: high-frequency welds of straight or spiral lines can be seen inside the seamed aluminum tubes. The wall thickness of seamless aluminum tubes is relatively thick, and there are no welds inside.

In terms of performance: seamless aluminum tubes have better pressure resistance and uniform texture than seamed aluminum tubes. The chemical composition and mechanical properties of the weld part of the seamed aluminum tube will change slightly. If it is a bent tube, it is recommended to use seamless aluminum tubes, and seamed aluminum tubes are prone to cracking.

In terms of function: seamless aluminum tubes can be used in important parts such as water stamping, air hydraulics, machined parts, grinding sleeves, etc. Seamed aluminum tubes are generally used as structural supports.
