Aerospace Applications of Molybdenum, Tungsten and Tantalum

As aircraft turbine engines require greater efficiencies, their designs require robust materials that withstand high thermal and mechanical stress.

H.C. Starck Solutions does not provide only molybdenum-based (TZM and Molybdenum Lanthanum Alloys) metal dies to forge precision fan blades and rotors, but also high performance powders to coat them providing an increased service life. Engine performance is optimized, backflow is diminished, fuel consumption is reduced and safer engine operation is enabled by thermal-spray application of insulation layers on turbine blades. H.C Starck Solutions’ AMPERIT product line provides these powders.
