Magnesium Alloys in Aerospace
The low density of magnesium combined with good mechanical
properties has made magnesium alloys attractive to designers for
many years. Consequently, magnesium alloys have been used
extensively in aerospace, defence and other engineering
applications, particularly for aerospace casings where weight is
always a major design factor.
Stone Foundries is one of the leading foundries in the world
with the expertise to produce magnesium alloy sand castings to the
levels of quality and structural integrity demanded by the
aerospace industry. The company has always been actively
involved in the development and improvement of processes to cast
magnesium.
In recent years, new magnesium alloys have been developed with
an excellent combination of mechanical properties and corrosion
resistance. Stone Foundries has worked closely with
designers, engineers and the alloy developers on the introduction
of these new alloys to aerospace applications.
The table below
details the Magnesium Alloys that we use.
