Product Overview

10% Titanium Aluminum is an aluminum-titanium master alloy with a nominal composition of 90% Al and 10% Ti. Titanium is present as TiAl3 particles that dissolve into molten aluminum at normal alloying temperatures, delivering titanium far more easily than pure titanium metal.

Titanium is used in aluminum for two purposes: to meet titanium specifications in alloys such as 319, A356, and 6061, and to refine grain size. The higher titanium content of this alloy, compared with our 6% Titanium Aluminum, means a smaller addition weight for the same titanium increase, which suits larger melts and alloy production.

Supplied as 16-17 waffle.

Use the 10% alloy when you need a larger titanium increase or are working with large melts, since it delivers more titanium per pound. The 6% alloy dissolves more readily and is often preferred for small trim additions.

Divide the titanium needed by 0.10. To add 0.1% Ti to a 1,000 lb melt you need 1 lb of titanium, or 10 lbs of 10% Titanium Aluminum.

Yes. Titanium above about 0.2% in most alloys can form coarse primary TiAl3 particles that settle as sludge and create hard inclusions in castings. Calculate additions carefully against the target specification.
