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.

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.
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.
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.
