Balance & Vibration Control


Aerospace & Defense




All mechanical systems generate noise and vibration that can be detrimental to overall performance. It can be particularly problematic in aerospace and aviation engineering where the frequency and amplitude of vibrations generated by flight control systems can neither be eliminated nor isolated.

    The solution is to integrate vibration dampeners into the mechanical architecture to restrict the oscillations produced by machinery before they can become problematic. H.C. Starck offers fully-machinable high-density tungsten (W) alloys that are uniquely suited for the fabrication of aerospace and defense-approved vibration dampeners.

    Tungsten Heavy Alloys for Vibration Dampeners

    Tungsten heavy alloy (WHA) is an exceptional engineering metal produced by sintering tungsten powders with a matrix of alloying elements, such as nickel (Ni) or iron (Fe). H.C. Starck Solutions offers high purity tungsten alloys with a density of over 60% higher than lead (Pb), ranging from 17—18.5 g/cm3. This promotes excellent vibration attenuation properties, helping to soften the oscillations of mechanical systems to limit the propagation of potentially harmful vibration.

    H.C. Starck Solutions closely collaborates with customers in the aerospace and defense industries to develop and produce custom parts to stringent customer specifications. Tungsten heavy alloy vibration dampeners can be engineering to extremely tight tolerances and in a wide range of geometries to meet unique designs for aircraft wings, rotor blades, combustion engines, and more. With over 30 years’ experience in the development of custom components from high-density refractory alloys, H.C. Starck Solutions is the ideal partner for designing and manufacturing vibration dampening solutions in aviation applications.

    With a secure, global supply chain and a collaborative approach to customer service, H.C. Starck Solutions consistently delivers high-performance material solutions to some of the most stringently regulated and demanding market sectors worldwide.
