Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the hexagonal lattice is more complicated than in cubic latticed metals like aluminium, copper and steel; therefore, magnesium alloys are typically used as cast alloys, but research of wrought alloys has been ...
They contain magnesium, aluminium, and strontium. [1] In the names the 'J' refers to Strontium. Alloy Mg Al% Sr% Mn% AJ62 Balance 6 2 0.34 [2] AJ52 Balance 5 2 0.4 [3] AJ52 has higher creep resistance, and AJ62 has better castability. Both are used in the BMW magnesium–aluminium composite engine block. [4]

Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.
Mn-free are very rare. Standard alloys are AlMg 3 Mn, AlMg 4.5 Mn 0.7, as well as for bodywork AlMg 4.5 Mn 0.4. Magnesium levels of up to 5% and manganese content up to 1% are used for wrought alloys. [8] [9] Mg contents up to 10% are also possible for cast alloys; however, contents of 7% and more are considered heavypourable. [10]
Modern scientific and engineering developments led to significant improvements in the quality of magnesium wheels, including high-tech anti-corrosion treatment that extends the lifecycle of a wheel to match or even exceed the life cycle of comparable aluminium alloy wheel. Forged magnesium started to displace sand and gravity die-cast magnesium ...
The way that the dry soils get a lot lighter between Table I on page 99 and table IV on pages 102-3 is eventually explained by the fact that Table I has pycnometer densities. For those who may already see reasons to learn more about the thermal conductivities of the soils it is free from the Army Cold Regions Research and Engineering Laboratory.
The air-cooled BMW 801 radial aero engine that powered the Focke-Wulf Fw 190 had a radiator fan made of magnesium alloy, very probably elektron. An advertisement in the German trade paper Flugsport in 1939 claimed that the record-breaking Arado Ar 79 aircraft contained 25% by weight of elektron, mostly in the Hirth HM 504 A2 4-cylinder inline ...
