Tungsten is a highly attenuative, highly reflective material. The
degree of attenuation depends on the grain structure. Because of the
high density, the impedance of tungsten is one of the highest of all
materials and it is about 100 g/cc^2 sec.

: Hi!

: My name is Derek Stewart and I am a graduate student
: at the University of Virginia. I am working on a problem
: where I am modeling acoustic waves in tungsten. However,
: so far, I have been unable to find any information about
: the acoustic attenuation in tungsten. I know this panel
: is specializing in transducers, but since you are also
: experts in ultrasonics, I was wondering if any of you
: would possibly know the value or possible references
: to explore.

: Thanks ahead of time,

: Derek
