ANCORBOND™ processing was the first commercial chemically bonded premix introduced in the ferrous Powder Metallurgy industry. ANCORBOND provides superior powder flow with reduced additive segregation, enabling greater depths of fill during compaction and the potential for higher compaction rates because of the enhanced flow. The greater alloying homogeneity of the powder premix offers reduced dimensional variation after sintering because of the diminished alloy segregation within any given lot. Continuous improvements to ANCORBOND processing yielded higher part densities and an ability to "chemically bond" greater concentrations of graphite and other fine particle additions.
Hoeganaes offers a die heat only premix alternative. The material referred to as AncorMax®200 utilizes dies heated to ~95 °C with no powder preheat. Benefits of this material include enhanced powder flow and higher part densities without the need to preheat both the die and powder. Certain limitations regarding part size and geometry exist; however, this premix alternative has proven successful in numerous applications. Engineered binder treated premixes for higher density and part performance.
A new machining system, designated AncorCut®, has been developed with improved stability and can therefore compliment MnS for use in PM steels. Turning tests were performed to evaluate the benefit of AncorCut on tool wear in different material systems.
Hoeganaes' iron powders are magnetic, which opens the door to many applications. From simple magnets, to induction heating of plastics, photocopy developers to seed separation, Hoeganaes' iron powders can be used in a wide variety of applications. Those made from the phosphorus alloys have higher resistivity, permeability and induction, and reduced coercive force. The presence of phosphorus also decreases the susceptibility of a P/M component to nitrogen aging. Components made from the phosphorus alloys exhibit a good combination of tensile strength, ductility, and impact absorption energy.
A high performance insulated particle material suitable for a variety of soft magnetic applications that require low core losses. Specific applications include ignition system components, electric motor components, solenoids, and inductors.
Ancorbraze® 72 is the premiere sinterbraze material for the joining of ferrous PM parts to each other, or ferrous PM parts to wrought substrates. Successful brazing can be done in the green or sintered condition. The chemical composition of the Ancorbraze 72 material – which can be utilized in the "as-atomized" or fluxed forms — effectively limits the penetration of the braze compound to the area immediately adjoining the desired interface. Each brazing application has unique characteristics due to variations in part composition and processing/sintering parameters. The typical Ultimate Tensile Strength of a brazed joint is 55,000 – 60,000 psi.
