Glossary
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.
- Electrolysis
Technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction.
- Electroplating
Coat (a metal object) by electrolytic deposition with chromium, silver, or another metal.
- Elongate
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.
- Ensat
Self-tapping threaded insert made of hardened steel
- Etching
Chemical surface treatment for the removal of impurities or to adjust certain surface qualities.
- Eutectic
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.
- Evaporation
Coating of aluminium components with various metals at elevated temperatures, which cannot be connected through metallurgical processes.
- Extrusion
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.
- Exudation
Leakage from the surface of enriched structural constituents; due to high temperatures when casting or annealing.
