Magnesium is the lightest of the structural metals. Sand cast and HPDC
Magnesium is used in a wide range of markets and applications, from
automotive to aerospace. In all cases, weight saving is the primary reason
for using Magnesium alloys.
Precision cast Magnesium is not in widespread use. Main reason for this
lies in the potential reaction of molten Magnesium with Silica found in most
shell moulds. Recent work has shown that by modification of mould
preparation procedures and use of low reactivity Alloy Elektron 21, metal /
mould reaction can be completely avoided.
Elektron 21 is corrosion resistant, produces uniform properties and can
operate up to 200oC. This combination of alloy properties, light weight and
precision casting technology will be attractive to many market sectors
where weight is a key factor.
