Induction Melting
Induction heating takes place when an electrically conducting
material
is placed in a varying magnetic field. The conducting material
can either be
the melt stock or the crucible in which it is to be melted.
Induction melting and vacuum sintering are used in powder
metallurgy and
for the production of other alloys. Typical melted products
produced in this
manner by Reading Alloys include aluminum-cobalt, nickel-magnesium,
and calcium-magnesium. These lines are also useful for research
and short
production runs.
Hydride-Dehydride Process
Reading Alloys has expanded its powdered metal capabilities with
the addition
of a new Hydriding/Dehydriding facility. The HDH
(Hydride/Dehydride) process
for powder production is the most cost effective method for
production of
a variety of specialty powders such as vanadium, titanium, and
niobium
for pressed parts and laser forming spray applications, as well
as coating
applications for the electronic, military, automotive and
aerospace industries.
Hydrogen impregnation (hydriding) into the grain structure of
metals enables
sizing of non-crushable materials into an infinite range of
particle distributions.
Since hydriding is totally reversible, powders can be produced
from high purity
feed stock (such as EB ingots) without compromising the starting
chemistry.
Reading Alloys can customize the particle size and distribution
of powder
products using a broad variety of powder processing equipment.
Cold Isostatic Pressing (CIP)
Cold isostatic pressing consolidates materials into workable
forms for
further processing. Powder raw materials are blended, packed into
a rubber
press bag and sealed. At very high pressures, the material is
compacted
to a solid with 65-85% of theoretical density.
