Automobile manufactures have transitioned to magnesium components due to its excellent strength-to-weight ratio. Magnesium is 75% lighter than steel and 33% lighter than aluminum, making it the lightest of all structural materials, without the need to sacrifice strength and rigidity. Additional benefits include:
Low density – offers a valuable ratio of mechanical properties per weight, resulting in 30% less weight to achieve similar strength
Better energy absorption – with low specific heat, magnesium requires lower energy consumption and benefits from a shorter cycle-time
Improved noise-damping – magnesium alloys have an enhanced capacity of vibration reduction than aluminum alloys and steels
Longer die life – the lifetime of the die is estimated to be twice as long as dies that cast aluminum
Strong and durable ‒ offers excellent dimensional stability as well as high-impact and dent-resistance; suitable for thin-walled parts
Ample supply and 100% recyclable ‒ the 8th most abundant element on earth with completely recyclable scrap material
