Liquid metal Defense Applications

Liquid metal Technologies has partnered with many Department of Defense research, engineering and development agencies, major defense companies and select universities to insert Liquid metal alloys as an enabling technology to enhance product performance and reduce weight. The material properties and characteristics of Liquid metal alloys make them highly beneficial for numerous Space, Air, Land and Sea military applications. Liquid metal alloys' technology provides for the optimization of properties for specific applications by tailoring the combination of process, chemistry and atomic structure. The net-shape processing characteristics of Liquid metal alloys make the fabrication of highly sophisticated and sound composite structures possible while eliminating most secondary machining and processing.

The properties of Liquid metal alloys suitable for the defense applications are:

High Yield Strength
• Unique Acoustical Properties
• High Hardness
• Low Melting Temperature
• High Strength to Weight Ratio
• Net-shape Casting
• Superior Elastic Limit
• Fabrication Process Similar to Plastics
• High Corrosion Resistance
• Non-Magnetic
• High Wear-Resistance

Awarded a series of multi-year, multi-million dollar contracts by the Department of Defense, Liquid metal alloys' technology is currently being developed for use as a Kinetic Energy Penetrator (KEP) rod. The KEP, the key component of the highly effective armor piercing ammunition system, currently utilizes Depleted Uranium (DU) because of its density and self-sharpening behavior. Ballistic tests conducted by the Army have proven that the Liquid metal tungsten composite KEP exhibits self-sharpening similar
to the DU KEP. As a result, the Department of Defense is working closely with Liquid metal Technologies to develop a new class of effective and environmentally benign KEP rods.

The high strength and lightweight attributes of Liquid metal alloys enable the Department of Defense to support its transformation toward lighter smaller and more cost effective systems. Liquid metal Technologies is supporting research and development for a wide range of military applications. Examples include:

Fuzes and Sub-Munition Components
• Lighter Weight Fragmentation Devices
• Composite Armor
• Aircraft Fasteners
• Light Weight Casings for Ordnance
• EMP and EMI Shielding
• MEMS Casings and Components
• Novel KEP's
• Thin Walled Casings and Components for Electronics
• Casings for Night Sights and Optical Devices
• Missile Components:Fins, nosecones, gimbals, and bodies
• Spacecraft, Aircraft, UAV & Ship Components

Liquid metal coatings, applied via thermal spray, provide high hardness with low friction. This characteristic is ideal for high wear environments. As the coating is mostly amorphous, little or no shrinkage occurs and thermal expansion is similar to that of typical steels. Test results demonstrate that Liquid metal coatings are very resistant to thermal and load cycling. Liquid metal coatings can be used to wear proof lighter materials such as aluminum and titanium to reduce system weight.
