A new Zinc-base alloy - ILZRO 12

Abstract

GRAVITY casting is one of the oldest processes of fabricating metals and alloys, and even today has special significance in a developing economy such as India's. The volume of production in deve- loping countries is often so low that rapid mass production methods, such as pressure die-casting, are often not economically very attractive. For making castings in small numbers, gravity casting method will continue to play an important role. Although brasses and bronzes have been widely used as gravity casting alloys since long and some alum- inium gravity casting alloys have come into vogue in comparatively recent times ; they are costly and present difficulties due to their high melting temperature. The present-day world is a competitive one and only materials having low costs and improved properties can survive the competition.
