HX5

HX5 Alpine Advanced Materials

A Composite Material Like Never Before.

HX5 is an ultralight and mechanically superior composite material, designed by Lockheed Martin Skunk Works® in a strategic effort to create the most capable, balanced and versatile thermoplastic blend in the world. HX5 boasts best-in-class mechanical properties that rival many traditional aerospace-grade materials at a fraction of the weight and is readily manufacturable by almost any process, from CNC machining to injection molding to extrusion. HX5 is an exceptional alternative to machined aluminum in nearly every application, offering equal or better performance at half the weight.

hx5 nanocomposite material

Having already been manufactured for use in jet fighters, high-speed helicopters, UAVs, amphibious transport vehicles, missiles, rockets and satellites, HX5 has proven its sustainability for a wide range of applications and environments. And, with clear advantages over machined aluminum, thermoset composites and other reinforced thermoplastics, HX5 is the only material for your performance challenges.

  • Chemically resistant: solvents, fuels, skydrol and DEET
  • Extremely corrosion resistant
  • Highly compatible with injection molding and extrusion
  • Machines like aluminum without chipping, cracking, galling or gumming
  • Extremely coatable (powder, electrostatic, spray)
  • Ideal for adhesive bonding and ultrasonic welding
  • Can be molded into complex shapes with very thin sections with exceptional dimensional stability
