Mechanical Testing

What mechanical testing is

Capalex can provide mechanical test certificates against a customers order. The tensile properties normally determined for these materials are tensile strength, proof stress and elongation.

The cost of the mechanical test certification depends on the specification required.


Tensile Strength

Tensile strength is determined for aluminium extrusions by the stress required to break a test piece in a tensile testing machine.


Adding the Tensiometer

Sample with the extensiometer being attached.


Proof Stress

Proof stress can be defined as the stress which is produced, (while the test load is applied) a non proportional extension equal to a specified percentage of the extensiometer gauge length. The extension specified when testing aluminium is generall 0.2%



Elongation is determined as a percentage increase in length of a stated gauge length inscribed on the tensile test specimen.
