Investment casting is one of the most versatile processes for producing parts from a wide variety of materials. From ductile iron and stainless steel to aluminum and super-alloys, virtually no other process can accommodate as many alloys and materials. It out-performs other forms of casting, forging, stamping, extrusion, permanent molding and more. Each of these other processes can be preferred for certain applications and situations, but across the board, investment casting is clearly best.
