[PSUBS-MAILIST] identify titanium

[Joe Perkel]

Hank,

A long time ago in a galaxy far far away, I once ground nicked dovetail slots back to specs on the No#1 Fan Disk of the GE CF6-50, (DC 10, Airbus). 

Jim is correct, it's non ferrous. However, Jim K is also correct, magnesium is bad news.

Hi All,

I'm far from an expert, however I'd use extreme caution with a grinder.

If it's magnesium it might start a fire you cannot put out!

If memory serves, I think they are similar in color in their natural state.

My two cents,

Jim K

Hank,
>First, if a magnet sticks it's not titanium. Touching titanium with a grinder should produce white sparks.  It has low thermal conductivity so it won't feel as cold as touching iron or steel.  That test only works if the piece is relatively cool. Not inside your house at room temp.  Hopefully someone can offer something more definitive.  What type of object?
