metal weights

[Mike and Jane Spalding]

Les,  The   density of titanium, according to the Marks Engineering Handbook, is approximately 60% of the density of steel.  The density of steel varies a little bit according to alloy composition, but all are within a couple percent of .285 lb per cubic inch.  That would make titanium about 0.171

hope that helps.

Mike
