Why Is 6061 Aluminum Seamless Tube Used For Hydrogen Fuel Vehicles?

The number of hydrogen fuel vehicles continues to increase, and hydrogen has become the gas of choice for new energy vehicles. It has the advantages of abundant resources, high calorific value, and cleanliness. Whether it is a hydrogen internal combustion engine vehicle or a hydrogen fuel cell electric vehicle, the problem to be solved is the storage of hydrogen.

At present, conventional steel pressure vessels cannot meet the requirements of lightweight and high hydrogen storage density for hydrogen fuel vehicles.
In the case of this demand, the large diameter aluminum seamless tubes with aluminum alloy 6061 are more and more used in hydrogen fuel vehicles as hydrogen storage tubes.

Advantages of large diameter aluminum seamless tube with 6061 alloy for hydrogen fuel vehicles:

  • The 6061 aluminum alloy is made of Mg and Si as the main alloy elements, and it belongs to the aluminum alloy that can be strengthened by heat treatment.
  • It has lightweight, medium strength, high corrosion resistance, no stress corrosion cracking tendency, and good welding performance.
  • The corrosion performance of the welding zone is unchanged, and the formability and process performance are very good.

Product name

seamless extruded aluminum tube for hydrogen vehicle, seamless aluminum tube for automobile, aluminum seamless tubing, large diameter aluminum tubing, large diameter aluminum tube, large aluminum tube, aluminum tube large diameter, large diameter seamless aluminum tube for vehicle.

Description Extrusion process can create extruded aluminum tube/pipe and extruded aluminum seamless tube/pipe. Compared to extruded tubes, seamless aluminum tubes have no welds and are preferred for hydrogen storage and pressure vessels.  The aluminum seamless tube has good mechanical properties, complete structure and good corrosion resistance. Large diameter aluminum seamless tubes usually refer to seamless aluminum tubes with an outer diameter greater than 100mm. (sometimes 200mm)
Material aluminum alloy 6061, 6063, 2024, 5083, 7075, etc.
Temper T4, T5, T6, etc.
Finish & Color anodizing, powder coating, sandblasting anodizing, brushed anodizing, etc.
Length CNC cut-to-length as per request.
Packing wooden frame, plywood case, shrink film.
Application The large diameter seamless aluminum tube with 5083 aluminum is widely used in ship and vessel, marine industry. The 6061 large diameter seamless aluminum tube is widely used in pressure vessel, hydrogen storage, vehicles and trailer trucks.

What FONNOV provide you on 6061 aluminum seamless tube for hydrogen fuel vehicle

  • Optimize the 6061 aluminum alloy composition

FONNOV adjusts the element content of 6061 alloy in weight percentage. This is because the medium in the hydrogen storage tube is a high-pressure gas, and the composition of each part of the tube and the various strengthening phases in the structure must be uniformly distributed and the grains are fine.

  • Optimize the heat treatment process and use H112 heat treatment

H112: Slightly strain-hardened from working at an elevated temperature from a limited amount of cold work (mechanical property limits specified). This can meet specific mechanical property requirements.

  • Control the critical dimensions

Control the roundness and straightness of the extruded tube. Control the inner diameter and wall thickness of the extruded tube, and ensure that the extruded tube can be inserted into the forced spinning mandrel.

What We need For Your Order or Quotation?

DWG (or PDF) File

The cross-section drawing includes dimension details, aluminum alloy and temper, length, dimension tolerance, critical dimensions, and inspection standard.

STEP File If Machining or Fabrication

If need CNC machining, bending, or assembly for your extrusion order, a STEP file will be necessary for our manufacturing. If need laser marking/etching of logo or series numbers, an AI (or CDR) file will be needed.

Finish & Color

Finish and color information is necessary for most architectural aluminum extrusion products. A super durable resistance request is also needed to provide for exterior use.


Quantity is necessary information that you should provide us together with your drawing for quotation. Different order quantities will make price changes.
