Tungsten, Molybdenum, Tantalum Aviation & Defense
Product Announcement from H.C. Starck Inc. - Fabricated Products Group
Molybdenum, Tungsten, and Tantalum for Aviation & Defense
As aircraft turbine engines seek greater efficiency, their designs necessitate robust materials that withstand extreme mechanical and thermal stress.
H.C. Starck provides not only molybdenum-based (TZM and Molybdenum Lanthanum Alloys) metal dies to forge the precision fan blades and rotors, but also the high performance powders to coat them providing an increased service life. Thermal-spray application of insulation layers on turbine blades optimizes engine performance, diminishes backflow, lowers fuel consumption, and enables safer engine operation. These powders are available through our AMPERIT product line.
Precision balancing of both fixed and rotary wing aircraft is critical to reducing vibration and enhancing pilot and passenger comfort. This is best achieved with dense, high-strength materials produced for optimum weight concentration. To help balance and stabilize the control surfaces of ailerons, elevators, and rudder sections of aircraft, helicopter rotor blades, and cockpit instrumentation, H.C. Starck offers complex-shaped balance weights manufactured from tungsten heavy metal alloys.
Providing both build-to-print components and design assistance, H.C. Starck provides tungsten, molybdenum, and tantalum products to the world’s premier warhead manufacturers. In line with other aerospace products, H.C. Starck supplies defense manufacturer’s tungsten alloy balance weights for missile bodies and sensor arrays. Finally, solid rocket motors use numerous specialty compounds to enhance thrust and molybdenum-based products (Powder Metallurgy and Arc Cast Grades) to guide propulsion though vanes and nozzles.
Completing H.C. Starck’s portfolio is its best-in-class extrusion and rotary forging facility where large complex shapes are extruded from specialty metals and alloy-based systems including titanium, nickel, molybdenum, tantalum, niobium and other high-tech materials for critical aircraft structural components.
Aerospace and Defense are important markets for H.C. Starck, who has been supplying to some Aerospace and Defense applications for several decades. As the industry performance requirements continue to grow, H.C. Starck is making investments in its materials and processing technology to support these requirements.
