Tungsten Counterweight
 

I am trying to source some tungsten (90%). I only need a1-2 kg. I keep finding referrences to aircraft counterweights.
Can someone let me know where these are usuallyplaced, what size, and any known source from a/c salvage people? I guess the size depends on the a/c size.

You might try Air Salvage International. Site - www.airsalvage.co.uk
They might be able to help or point you in the right direction.

Another common material for counterweights is depleted uranium... so it will depend on aircraft.

It's used as counter weights and vibration absorbers on several types of helicopters.

If there are any helicopter operators in your area, have a word with someone there.

Tungsten is very commonly used for main rotor blade, tip weights. (because of the very high density, it helps give the blades high inertia).

Once the blades are time expired, they are usually cut into scrap.
These weights are fairly sought after by sheeties, as they are very good for riveting blocks, but you might be lucky. (especially if the transaction involves a few tinnies!)
