Aluminium profiles and tubes

Function

• The tube is the connecting part between engine unit and gear unit. Inside the tube there is a driveshaft with bushings or a liner.

Technical requirements

• The runout demand is from 0.5mm to 1.8mm (depending on the length of the tube).

• Tubesplit test is required for both welded and extruded tubes. This is for testing the strength of the weld line or the extruded tube.

Dimension, Weight and Material

• Diameter from 24mm up to 42mm. General material thickness is 1,5-2mm.

• Example of material for tubes is Al alloy 5086H18, SIS 4212-06

• Example of surface treatment is anodized 5-10µm.

Production process

• Extruded or welded aluminum tubes.

• In some cases the burrs of the weld have to be removed and tube brushed internally.

• There is demand for fine cutting on extruded tubes, burr max 0.2mm.
