Ferrotitanium lumps.
Like ferrochrome, ferrotitanium is a master alloy used in creating iron/titanium alloys that contain a much smaller percentage of titanium. It's just easier and cheaper to ship the titanium in the form of already mixed alloys, rather than in pure form. For one thing, it's rather hard to melt pure titanium to get it to go into the alloy you're trying to make.
