Properties of HX5:

HX5 vs. Aluminum
The extreme mechanical performance of HX5 was characterized by a broad range of standard ASTM tests important to aerospace, defense and space design engineers with a goal to replace 6061-T6 aluminum with a material of the same strength, yet half the weight.

HX5 vs. Thermoplastics
HX5 also enables robust composite structures with best-in-class properties compared to other industry standard thermoplastics.

HX5 vs. Aluminum
HX5 thermal properties are important for stable structural designs in elevated temperatures. HX5 boasts a high Heat Deflection Temp (HDT) that is five times less than typical aerospace-grade aluminum, and a low Thermal Conductivity. The combination of these properties is ideally suited to greatly reduce twisting, warping, and fatigue of molded structures in high thermal gradient environments.
