EternAloy (formerly Allomet) produces EternAloy TCHP (Tough-Coated Hard Powders), a nano-engineered powdered metal product line that offers combined hardness and toughness beyond any other material ever produced and enables extreme wear-resistance.

We utilize a flexible, proprietary, globally-patented, nanotechnology-based process to carefully coat 2-50 micron-sized hard core particles (ceramics, superhards, carbides) of any shape with 50-500 nanometer-thin tough coatings and an extremely strong outer shell coating to create EternAloy® TCHP.  Employing conventional methods, TCHP is then applied as a surface coating (via thermal spray or laser metal deposition) or pressed and sintered into solid body shapes (cutting tools, wire dies, etc.).  The resulting applications exhibit unsurpassed levels of extreme wear-resistance over a very wide temperature range for high-value applications where productivity, reliability, efficiency, and safety are a critical priority to the customer.

The TCHP production process is customizable to meet desired specifications, allowing a hard core particle to be selected from a range of 30 types to provide desired thermal conductivity/insulation, strength, wear, fatigue life, and toughness characteristics.  Applications can include: 

Machine tools
Wire dies
Ballistics
Turbine and aircraft components
Oil and gas drills
Automotive engine components
Bearings
Rollers/extruders
Hazardous waste storage containers
Heat exchangers
Valves
Pipe interiors/exteriors
Medical devices
