Lo-Ex
Lo-Exis analuminium alloywith a very small thermal expansion co-efficient. It contains approximately 14 per centsilicon,2 per centnickel,and 1 per cent each ofcopperandmagnesium.[1]
Applications
[edit]It has been used extensively and successfully over the years for all types of piston,[2]including inHillman Imp,[3]andTerraplane[4]engines.
LM13 is a related alloy in the Lo-Ex series, also widely used fordiesel enginepistons.[5]This alloy contains 12% silicon, 1% copper and 1% magnesium.[5]Both of these alloys have also been used in a strengthened form, reinforced by anMMCorhybrid compositeofaluminaor zirconium ceramic fibres. These alloys have been worked bysqueeze castingorstir casting.[5]
