Why magnesium die casting? The assured availability and the combination of positive properties of high-purity magnesium alloys make this lightest of all metallic engineering materials an attractive option for numerous applications such as:
Light-weight components in automotive engineering. Casings of office machines, notebooks, cell phone handsets, loudspeakers. Power tools, etc.Features and advantages of the process.
The excellent flow characteristics enable components to be cast with even thinner wall sections or higher complexity than with aluminum die casting. New applications in the electrical engineering industry thanks to the good thermal conductivity and the electromagnetic screening of the metal. Higher strength and better thermal conductivity are achieved than with plastics. Magnesium supplies are all but inexhaustible. The return scrap can be readily recycled. High-purity magnesium alloys are not prone to corrosion. Good soundproofing properties. Weight reduction compared with aluminum about 35%.The alloy is selected based on the environment the part will function in the performance requirements of the component.
AZ91D: Most commonly used alloy for high pressure die casting. Offers good strength to weight ratio, very good corrosion resistance and excellent castability. This alloy is typically used for power-train and mechanical components where toughness is more important than deformation capability.
AM60B: Commonly used for automotive die castings for safety components such as instrument panel structures and seat frames. This alloy offers excellent ductility, energy absorbing properties, strength and castability.
AM50: With a lower aluminum content than AM60 this alloy offers a further increase in ductility but at a slightly reduced strength and a slight reduction in castability. It is typically used where the performance requirements demand elongation properties beyond that of AM60
