Magnesium alloys: Magnesium is the lightest among structural metals (specific weight 1.74 g/cm3, thus 35% less than aluminium). Magnesium alloys are characterized by extreme lightness, high resistance to impact and vibration, they do not stretch nor are they damaged superficially by friction: this is another characteristic that makes them particularly appropriate for the production of racing

Flame temperatures of magnesium and magnesium alloys can reach 1.371 C (2,500 F), although flame height above the burning metal is usually less than 300 mm (12 in). Magnesium may be used as an ignition source for thermite , an otherwise difficult to ignite mixture of aluminium and iron oxide powder.
Magnalium - Hyperleap
However, these alloys are flammable when powdered, are more resistant to corrosion than pure magnesium, and are more reactive than pure aluminium and are therefore used in pyrotechnics as a metal fuel and to produce sparks. Although they are generally more
Corrosion of Magnesium and Magnesium Alloys
Corrosion of magnesium alloys increases with relative humidity. At 9,5% humidity, neither pure magnesium nor any of its alloys exhibit evidence of surface corrosion after 18 months. At 30% humidity, only minor corrosion may occur. At 80% humidity the surface
Effect of Tin Additions on Microstructure and Mechanical …
Commercial cast magnesium alloys for automotive appliions are AZ and AM series alloys (AZ91D, AM50A, and AM60B) 3. Magnesium alloys generally offer good castability, In Mg-Al alloys, castability improves with increasing aluminium content due to the improved fluidity, but aluminium also increases the tendency to shrinkage, hot cracking and microporocity problem.
Investigation on Mechanical Behavior of LM4 Alloys Reinforced …
magnesium alloys are both lighter than other aluminium alloys and much less flammable than alloys that contain a very high percentage of magnesium. Use of soda-lime glass as reinforcement in aluminium alloys has received little with superior corrosion
Corrosion Protection of Magnesium Alloys by Functional …
These features grant to magnesium and magnesium alloys a high strength-to-weight ratio (Čížek et al. 2004). Its low density makes magnesium lighter compared to other structural metals. For example, aluminum (density of 2.7 g/cm 3 ) is 55% heavier than magnesium, and for steel (density of 7.86 g/cm 3 ) that value reaches almost 352% (Kulekci 2008 ).
Why is magnesium alloys better to make a car with than …
Usually, Alloys have better properties - like strength-to -weight ratio - than the parent metals. Pure Magnesium is also a bit nasty to use and work with as it can ch fire.
