Magnesium, an alternative to aluminum, is used as a primary alloy for an increasing number of laptop designs. Rare earth (RE) elements, such as CeGd, Nd and … It’s lighter by volume than aluminum by approximately 30% (it’s actually the lightest structurally-used metal in the world), while having a greater strength-to-weight ratio. This is because magnesium alloys lack formability for wrought applications, and their high cost discourages the use of magnesium alloys for automotive applications. But there are also opportunities to incorporate the material into business class seats. Magnesium alloys are produced in various forms including casting, sheet and plate, shapes, forgings, bar, and rod. Magnesium or its alloys are available in almost all the common forms in which metals are commercially used. Uses of alloys. In 1924 magnesium alloys (AZ; 2,5–3,0% Al; 3,0–4,0% Zn) were used in automobile pistons diecast by Elektronmetall Bad Cannstatt, another IG Farben company formed out of Versuchsbau Hellmuth Hirth. For any particular use, an alloy is matched that has the most suitable range of properties. Practically pure magnesium, 99.8 per cent, is supplied as ingot and stick for remelting, and as powder, ribbon, wire, and extruded and rolled strip. Magnesium alloys are also used in many other engineering applications where being lightweight is a significant advantage. The company is still manufacturing alloys in 2017. Magnesium alloys have traditionally been specified by designers because of their favourable strength to weight ratios Magnesium is approximately two thirds the density of aluminium and a quarter that of steel. Uses. Some of the more recently developed magnesium alloys have improved resistance to corrosion and better all round mechanical properties, especially at elevated temperature. Zirconium-free alloys, principally AZ91 but also other alloys, are used in … Magnesium has a reputation for being highly flammable, and in the past magnesium alloys were not allowed to be used in airplane interiors. have different properties to the pure metal. Magnesium-zirconium alloys tend to be used in relatively low-volume applications where they are processed by sand or investment casting, or wrought products by extrusion or forging. Elektron has been used in aircraft, Zeppelins, and motor racing applications. Alloys. Panasonic Avionics in collaboration with B/E Aerospace last year unveiled a new ‘Jazz’ seat that uses magnesium alloys in limited applications. Cast alloys, widely used in interior and power-train components, account for more than 99% of magnesium alloys used today, while only a small number of wrought products are utilized.
