Founding properties on non-ferrous liquid metals

ALTHOUGH the liquid state is the first step of all founding operations no fundamental measure is available to evaluate the capacity of liquid metals to flow adeq-uately into intricate moulds. Whilst a consideration of viscosity & surface tension is natural in any discussion of the flow of liquid metals, it is not adequate to describe their founding characteristics.In this paper an attempt has been made to evolve a fundamental basis of viscosity and surface tension and their impact on casting fluidity
