Heat treatment of wrought aluminium alloys

Constitution of the different types of alloy: The main alloying elements in aluminium engineering alloys are manganese (Mn), silicon (Si), zinc (Zn), magnesium (Mg) and copper (Cu). In accordance with the international classification system and EN 573, the different types of alloy are divided into groups with a four-figure designation: 1XXX (Al

Health aspects

We all come into contact with aluminium in one of its various forms every day. Without doubt the best known is as a metal, which forms the basis for many of the consumer goods we use daily. However, we also come into contact with it in other ways. Aluminium is always present in nature combined chemically with other materials, i.e. in non-metallic

Heat treatment: Non-age-hardenable wrought alloys

Hardening mechanisms: This group includes unalloyed aluminium and the AlMg, AlMn and AlMgMn type alloys. With these alloys, increases in tensile strength are achieved by means of cold working and solid-solution hardening. The tensile strength Rm is usually used as the characteristic value to evaluate strength properties. The diagram alongside

Health aspects: Drinking water

All over the world, most waterworks use aluminium sulphate as a flocculant to provide drinking water. Flocculants are used in drinking-water treatment to tie up small inorganic particles and bacteria present in the water and to filter them out. While some waterworks can manage without this treatment, there are others whose water is so turbid (

Hybrid Welding Processes

Laser MIG hybrid welding is only one of a variety of examples in which one attempts to combine the advantages of the different processes involved; a robot-guided laser is used together with a robot-guided MIG torch. The laser beam impinges orthogonally on the welding zone and creates a plasma channel whereas the MIG torch is positioned at an angle

Health aspects: Food and packaging

Aluminium is used in many different ways in the preparation, protection and storage of food and drink. It is an extremely good conductor of heat and makes very efficient use of energy when preparing and serving both cold and hot dishes. In addition, aluminium is very light. This reduces transport costs and makes aluminium the ideal material for

Hybrid construction project

The car industry aims to put cars on the market which have lower fuel consumption. One of the possibilities like one can realise this plan is to reduce the weight of the car body. The method of hybrid construction, also called multi material design, is the current trend of the branch. The principle is easy: to use the right material at the right
