Titanium Ingots are ingots crafted from Titanium Dust.
Titanium ingots are produced by smelting Titanium Dust in an Industrial Blast Furnace. Titanium dust is obtained as a by-product of placing Bauxite Dust in an Industrial Electrolyzer. (2 tiny piles is obtained per 12 bauxite dust) or macerating certain ores in an Industrial Grinder. There is also a small chance that they will spawn in chests.
Titanium Ingots are used in many high-end machines. It is one of the components to craft a Highly Advanced Machine Block. It can also be used in some of the alternative recipes to craft more basic products, such as Mixed Metal Ingots. Harder GregTech recipe also requires titanium ingots to make a Mining Laser, Diamond Drill and Jackhammer.
Important note: The dust has to be smelted in an Blast Furnace, so a regular Furnace will NOT work!
