The Allomet Corporation is a privately owned company located in North Huntingdon, Pennsylvania that produces a line of patented powdered metal products known as EternAloy® Tough-Coated Hard Powders (TCHP).

History

The Allomet Corporation (formerly EnDurAloy) was founded in Savannah, GA in 1996 and incorporated in March 1998. In November 2002, Allomet Corporation moved its headquarters and manufacturing facilities from Savannah, GA, to its current location, a 10-acre site in North Huntingdon Township, Pennsylvania.

Tough Coated Hard Powders (TCHP)

Overview

The development of TCHP materials is rooted in the cemented carbide industry, and the majority of current TCHP materials encapsulate a ceramic or superhard “core” particle into a cemented carbide shell. Thus, TCHP material applications are closely related to the typical wear applications of standard cemented carbides.

Characteristics

TCHP’s are produced through a proprietary powdered metal processing technology which has the ability to uniformly coat 2-50 micrometer-sized hard core refractory particles of any shape (spherical, block, random, etc.) with 50-500 nanometer-thin tough coatings. These “core” particles are first coated with an intermediate encapsulating layer of tungsten carbide (WC) followed by an outer encapsulating binder layer of cobalt (Co) or nickel (Ni), giving the powder its double shelled structure.

When sintered or applied using thermal spray methods, the tough outer layers chemically bond, forming a metal matrix in the sintered article or deposited coating, This hybrid material combines the high strength, heat resistance, and toughness of cemented carbides with the chemical and abrasion wear resistance of the harder core particles.
