Article: Specialty compounds replace diecast metals.

Die-cast metals have a combination of stiffness and light weight which makes them ideal candidates for many industrial components requiring precision assembly, particularly in dynamic or portable applications. Typical components are brackets and chassis which have to position and maintain other components in precise relationships.

The stiffness of die-cast metals - a specific modulus roughly 10 times that of engineering plastics - and the ability to pressure diecast them into thin sections make them a hard act to follow in terms of replacement by plastics. But there are benefits to be gained in terms of overall cost and some end properties, such as appearance, which ...
