EternAloy® Tough-Coated Hard Powders (TCHP)

• TCHP is Tough-Coated Hard Powder nano-scale engineered material that offers extreme

combinations of desired properties, including:

• High toughness

• Hot hardness

• Abrasive wear resistance

• Chemical resistance

• Low friction coefficient

• Low weight

Conventional materials are either hard or tough…..but not both.

EternAloy® TCHP solves that critical challenge.

• TCHP is formed by uniformly applying a very tough outer shell and strong matrix binder

coating to a hard core particle…..at an extremely small scale never before possible.

Result: As a surface coating or a solid body shape, TCHP has contact face hardness near

that of the core particle and toughness equal to or better than the matrix binder

over a very wide range of operating temperatures!

The Allomet Customer

Value Proposition

We utilize a flexible, proprietary,

globally-patented powdered metal

processing technology

to carefully coat 2-50 micron-sized

hard core particles of any shape

with 50-500 nanometer-thin tough coatings

to create

EternAloy® TCHP

that possesses

extreme combined

hardness and toughness

for high-value use

as a surface coating

or formation into a solid body shape

like conventional materials

to provide

unsurpassed levels of wear-resistance

over a very wide temperature range for

high-value productivity, reliability,

efficiency, and safety applications.

What is TCHP?

Proven Application Example: TCHP wire dies last 7X-10X longer than

tungsten carbide dies when forming high-carbon steel wire

• Machine tools

• Wire drawing dies

• Ballistics

• Turbine components

• Aircraft components

EternAloy® TCHP

provides unsurpassed combined hardness & toughness over a very wide temperature range

to enable new levels of extreme wear-resistant performance for high-value

surface coating and solid body applications, including:

• Oil and gas drilling tools

• Medical devices

• Automotive engine components

• Bearings

• Industrial manufacturing components

TCHP is a game-changing innovation for any wear-resistance application

where productivity, reliability, efficiency, and safety are of high value….

TCHP Applications

• EternAloy®

TCHP: Unsurpassed wear-resistance for high-value applications
