Aluminum is our passion. And our knowledge! Benefit from our knowledge.
Many information can be found in aluminum-manual, which is being completely revised and will soon be available. In the meantime, please use our glossary for useful word explanations.
- Elastic deformation
Temporary change in length, volume, or shape produced in an elastic substance by a stress that is less than the elastic limit of the substance.
- Elastic modulus
Mechanical property of linear elastic solid materials that describes the ratio of the force exerted upon a substance or body to the resultant deformation.
Technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction.
Coat (a metal object) by electrolytic deposition with chromium, silver, or another metal.
Mechanical treatment of rolled plates with tensile stress to reduce residual stresses.
- Elongation at break
Ratio between changed length and initial length after breakage of the test specimen.
Self-tapping threaded insert made of hardened steel
Chemical surface treatment for the removal of impurities or to adjust certain surface qualities.
Mixture of substances (in fixed proportions) that melts and freezes at a single temperature that is lower than the melting points of the separate constituents or of any other mixture of them.
Coating of aluminium components with various metals at elevated temperatures, which cannot be connected through metallurgical processes.
Pressure forming processes; a workpiece is shaped by being pushed at high forces through a die of the desired cross-section.
- Extrusion billet
Cast metal block with mostly circular cross section that is suitable for pressing.
Leakage from the surface of enriched structural constituents; due to high temperatures when casting or annealing.
