Aluminium is our passion. And our knowledge! Benefit from our knowledge.

Many information can be found in aluminium-manual, which is being completely revised and will soon be available. In the meantime, please use our glossary for useful word explanations.

Tensile strength

Value determined in a tensile test; the maximum amount of tensile stress that it can take before failure, for example breaking.

Tensile test

Destructive material for determining the mechanical properties of tensile strength, yield strength, elongation at break and breaking constriction, standardized according to DIN EN 10002.


Metallographic structure of metals after a deformation.

Thermal conductivity

Ability of a material to transport thermal energy by means of heat conduction.

Thermal expansion coefficient

Describes changes in the geometry of a material when subjected to temperature changes.

Threaded insert

Hollow cylinders with internal and external thread to reinforce / strengthen screw connections.
