Lost Wax CTE?

A long shot possible, but does anyone know the CTE for lost wax casting wax?
cheers

    I don't know what CTE means but it sounds as though you might be looking for Alex Tiranti's. If so, risk life and limb and try http://www.tiranti.co.uk/subdivision_product_list.asp?SubcategoryC&Subdivision --

CTE is coefficient of thermal expansion. Its how much bigger a meter of a thing gets for a 1 degree rise in temp (usually, tho inches and stuff are also available ;) Been to Tiranti to buy wax for testing a 'thing' at work, but no detail info there.

1.7 x 10^-4 /K is a typical value, but it varies with the wax of course. Makers of good commercial waxes should have more accurate figures for their waxes available.

Cheers Peter, that will be accurate enough. Main point is its significantly different from Titanium, and may warrant thermal controls when measuring masters.

Yes, it's quite high - you can get low expansion casting waxes, but these are usually more expensive, if nothing else (ie not sold as such).
