TITANIUM ALUMINIDEs     product overview 

Ingots made from Titanium Aluminide are manufactured by melting consumable electrodes once or multiple times with the respective target composition in the vacuum arc furnace (VAR). A part of this ingot is re-fused in the VAR skull melter, homogenized, and poured out into molded parts in a centrifugal casting process or gravity casting. Depending on the requirements, these molded parts can be hot isostatic pressed (HIP) into non-porous semi-finished products and heat-treated to set specified structures. Mechanical processing according to a drawing can be done by customer request.

With the cold wall induction crucible furnace (ISM, Induction Skull Melter), an effective technology for recycling qualified waste materials is available. The waste materials fused and homogenized in the ISM can be poured off into molded parts and processed further, just like the VAR SM process.

Sheets, rods, and profiles can be manufactured from cast TiAl semi-finished products using extrusion presses or rollers.
