Magnesium is 33% lighter than aluminium, 60% lighter than titanium and 75% lighter than steel with excellent elongation and ductility properties. Industry observers anticipate a resurgence in its use through the 21st Century as it has great benefits to offer as a structural material.
A lot of the demand is emerging from automobile and aerospace manufacturers who are increasingly shifting towards magnesium-alloys to reduce vehicle and aircraft weights and meet growing fuel-efficiency demands. There is an abundant supply - magnesium is 4th most common element in the Earth (after iron, oxygen and silicon) and it is 100% recyclable.
Corrosion resistance is critical and die cast magnesium components can be powder coated or e-coated. Powdertech Surface Science has been powder coating magnesium for over ten years, operating all large automotive OEM approved magnesium chrome-free pre-treatment systems. For aerospace-approved magnesium alloys to class L (with top coat) or class S (no top coat) specification we use Gardobond X4729 eleven-stage chrome-free pre-treatment.
