HX5: A cutting-edge material for defense applications

Alpine’s groundbreaking HX5 is an advanced thermoplastic nanocomposite that replaces aerospace-grade aluminum. HX5 is not only comparable to aluminum in strength – at just half the weight – but it has much greater resistance to extreme environmental conditions and has dramatic manufacturability advantages. HX5 is the only material of its kind on the market today.

HX5 has been exhaustively tested for military applications and has been certified for use in the most demanding situations. It is currently being employed in jet fighters, high-speed helicopters, UAVs, amphibious transport vehicles, missiles and satellites.

Thermal Properties ASTM HX5 6061 T6
Coefficient of Thermal Expansion, (L/L/°F) E 831 2.11 X 10-6 13.1 X 10-6

ENVIRONMENTAL STABILITY

HX5 is engineered to survive

  • Meets rigorous DoD guidelines for flame, smoke, and toxicity

  • Extremely resistant to solvents, fuels, lubricants, and chemicals

  • Satisfies NASA spacecraft limits on outgassing and radiation resistance stability (doesn’t degrade in space)

  • High temperature capable

  • Passed accelerated lifetime thermal cycling and high-temperature thermal stability

  • Galvanic corrosion resistant

MANUFACTURABILITY

Engineered to be versatile

  • Drop-in material for many injection molding operations

  • Low shrinkage and excellent dimensional stability (0.5% vs. 2.0%)

  • Enables part consolidation into a single molded component

  • Compatible with metallic insert molding operations for multifunction products

  • One material formulation compatible with many manufacturing operations:

    • Injection molding
    • Profile extrusion
    • Compression molding
    • Thermoforming

SECONDARY OPERATIONS

HX5 is engineered to process like a metal

  • Machines like aluminum without chipping, cracking, galling or gumming

  • Taps and threads like metal

  • Unlike most solvent resistant materials, can be coated, primed, painted and adhesively bonded

  • Can be metallized to meet EMI shielding requirements

Testimonials

I’ve been searching for new materials to advance our innovative concepts in the aerospace interiors market for some time. HX5 allows us to create cutting edge lightweight designs that are a game changer for the industry.

Adam White, Factorydesign

We are bringing revolutionary technology to the commercial sector that will significantly address the greenhouse gas concerns encountered by the aerospace industry. Our target is to reduce carbon emissions of a commercial single-aisle passenger plane by over 600,000 lbs. per year.

Joe D’Cruz, Catalyze Dallas

HX5 was designed to weigh 50% less than aerospace-grade aluminum, without loss of the strength, performance or environmental durability required in aerospace and defense applications.

Dr. Slade Gardner, Former Fellow at both Lockheed Martin Space Systems Advanced Technology Center and Skunk Works®, and Chief Technical Advisor To Alpine Advanced Materials

It’s great to see this special innovation that was purpose-built for Lockheed military programs become available for light-weighting programs across many industries. I can see broad application potential not only in commercial aerospace and rotorcraft but also in general transportation, energy and in the broader defense market.
