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 ...
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]
AJ alloys (AJ52 and AJ62) are die castable alloys of magnesium that have good creep resistance at high temperature. 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]
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 AlMgSi alloys are therefore understood in the standards as a separate group (6000 series) and not as a subgroup of aluminum-magnesium alloys that cannot be hardenable. AlMgSi is one of the aluminum alloys with medium to high strength, high fracture resistance, good welding suitability, corrosion resistance and formability. They can be ...
Tensile strength σ t) 195–290 MPa (28.3–42.1 ksi) ... 5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat ...
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 ...
These alloys commonly contain manganese and zinc, but there are other combinations known. Some common alloys are named HK31, HM21, HM31, HZ32, ZH42, ZH62; where the "H" indicates that the alloy contains thorium. Magnesium alloy names are often given by two letters following by two numbers.
