Aluminum So-called Titanium racket
So-called "Titanium" racket.
"Racket" may be the right word for this sample, which used to be a racquetball racket prominently labeled as "TITANIUM". If it were titanium, it wouldn't have melted at about 700C in my crucible of truth.

It gets worse. It could have been one of many commonly used high-strength aluminum-titanium alloys, which contain a few percent of titanium: That would almost justify the use of the name "titanium" in the description. But analysis by x-ray fluorescence spectroscopy at the Center for Microanalysis of Materials, University of Illinois (partially supported by the U.S. Department of Energy under grant DEFG02-91-ER45439) indicates the following composition:

98.44% Aluminum
0.55% Manganese
0.53% Copper
0.24% Iron
0.16% Zinc

Where's the titanium you ask? It's not there, not even the tiniest trace.
