Magnesium – Best Strength-to-Weight Ratio

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


As the material of choice for metal casting manufacturers, aluminum’s superior performance has been universally accepted by the automotive industry.

Highly customizable ‒ allows for complex designs of die cast parts

Strong, yet lightweight ‒ superior to other metal alloys in terms of strength and weight

Flexible and durable use ‒ corrosion-resistant with extended lifetimes, and versatile enough to be used for a broad range of applications

Robust properties ‒ features high thermal and electrical conductivity, reliable mechanical properties, and retains its strength even at high temperatures

Cost-efficiency ‒ less expensive to manufacture, simple to recycle, and results in quality metal products at affordable prices
