The influence of casting technique on elongation and other mechanical properties of low-ductility dental casting alloys

A study was made of the effect of mould orientation on the mechanical properties of eight dental cobalt-chromium alloys prepared by centrifugal casting. In general, tensile test bars cast with their length horizontal rather than vertical to the induced gravitational field yielded superior elongation and ultimate tensile strength values. Proof stress was less affected by casting conditions.
