Get more information about tungsten copper alloys
Heavy metal alloys are called as pseudo alloys of tungsten by having a nickel copper
matrix or nickel iron. Tungsten copper alloy are made by powder metal and sintering
procedure. The best property of tungsten copper alloy is the extreme density of 17-19
g/cm3. Other densities that are comparable are attained by platinum or gold metals
that are very costly.Other outstanding materials such as uranium, rhenium or tantalum
attain these densities. But they are very tough or costly to get or they contain
insufficient mechanical features.
Production:
Great techniques of powder metallurgy create it possible to mix the low level of usage
of tungsten and the great level of electrical conductivity of copper in to single
material.Tungsten copper alloy manufacturers produce the alloys by compressing the
tungsten powder in to a secure body.At the time of sintering on vacuum, the cavities
are saturated with liquid copper.By difference of the producing parameters like
compressing, soaking metals and sintering process, the properties can be used or
practiced to the application.Electrode and contact materials want to satisfy stringent
needs relating the electric conductivity when giving low levels of taking by the
electric arc.These alloys contain high level of resistance to take, Efficient and same
electrical conductivity, Easy machinability with great mechanical strength and low
alloying methods between electrode and job material.
Best choice:

These alloys are the right option where great density, extreme thermal conductivity, or
little level of thermal expansion are essential.Heat sinks, electrical contacts and
resistance welding electrodes are the applications where these alloys can perform the
function.Examine the choices and properties to decide that of the alloys is highly
suitable for your requirements.Most of the shapes and sizes can be given with short
time by the tungsten copper alloy suppliers.The suppliers can also produce these
materials according to your specifications.

Advantage:
The benefits are high thermal conductivity, high arc resistance mixed with best
electrical conductivity and low thermal expansion.The application of these alloys are
electrodes in EDM or electric spart erosion, vacuum and arc contacts in both medium
and high voltage breakers, heat sinks for accepted cooling of electronic equipment
and electrodes for resistance welding.Actually tungsten copper is one of several metal
alloys sold by AE alloys. Usually instantly found in huge quantities. They are

available like ingot, bar,shot, wire, ribbon, foil and sheet.High purity methods and
modern high purity methods include submicron powder, metal powder, targets for
thin film accumulation, physical vapor accumulation, pellets for chemical vapor
storage.

Different grade:
The manufacturers produce to large number of best grades when needed like ACS,
technical grade, reagent and milspec, optical grade, pharmaceutical grade, food and
agricultural grade and follows needed ASTM examination standards.Usual and
personalized packaging is also available. Main application are like ballast, bearing
assembly, radiation protection and step soldering.Only best purity raw materials are
availed in the process and there are no lubricants helps included.They have best
feature like ablate resistant, heat resistant, high density, high intensity and self cooling
feature that create them highly availed in spaceflight industry.Get high quality of
these alloys by visiting http://en.ofweek.com
