A new Zinc-base alloy - ILZRO 12

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.
