Tungsten high density alloys (WHD)

Haines & Maassen offers tungsten high density alloys with different alloy surcharges. These tungsten alloys are characterized by an high density, which is close to this of pure tungsten. Their advantage lies in a much better workability.

Next to its obvious use as a balance weight, the ability to absorb x- and gamma radiation makes it a usefull alloy in many technical application. High density tungsten alloys are described in the ASTM B 777 norm.

Possible apliccations

In comparison to pure tungsten, WHD parts are much easier and cheaper to produce. It is possible to produce in much smaller and delicate dimensions.

Properties	Tungsten/Nickel/Iron	Tungsten/Nickel/Copper
Electrical conductivity	lower	higher
Thermal conductivity	high	higher
Magnetic properties	slightly magnetic	not magnetic
Hardness	little softer	little harder
Tensile strength	higher	lower
Density	between 17 and 18,5gr/cm³	between 17 and 18,5gr/cm³
Thermal Expansion	low	low

Forms of delivery

We have Rods of WHD18 (WNiFE and WNiCu) on stock in diameters from 5-50mm. On request wie also offer other forms of delivery in various alloy compositions with different densites.
