Magnesium alloys are mixtures of magnesium (the lightest structural metal) with other metals (called an alloy), often aluminium, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys.
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]
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 ...
Aluminium magnesium boride or BAM is a chemical compound of aluminium, magnesium and boron. Whereas its nominal formula is AlMgB 14, the chemical composition is closer to Al 0.75 Mg 0.75 B 14. It is a ceramic alloy that is highly resistive to wear and has a low coefficient of sliding friction.
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]
It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C. [2] Alloy 5083 is also commonly used in cryogenic applications due to it being able to be cooled to -195 ...
Alloys with small amounts of magnesium (about 5%) exhibit greater strength, greater corrosion resistance, and lower density than pure aluminium. Such alloys are also more workable and easier to weld than pure aluminum. [1] Alloys with high amounts of magnesium (around 50%) are brittle and more susceptible to corrosion than aluminum.
