Peanuts compared to gold
The expensive part here is the 1/16 inch gold around the tungsten to fool x-ray scanners, they say that's enough to prevent x-rays from reaching the tungsten.
Around US$ 40,000/tonne, $40/kg. Roughly a dollar an ounce, vs nearly $2000 for gold.
with a thick gold plating ? They must have ways to get really cheap gold.

Long time reader but first time poster, had to share a story.
A decade ago was riding a bus in China, and they had a PSA type ad playing on the screens (paraphrased) "making sure when you're buying gold you distinguish investment (real) gold bars and decorative (fake) gold bars".
I thought "wow, how bad of a problem it must be to need such a PSA".
Oh good, I'm sure nothing bad will happen since they wrote the disclaimer.
How much does tungsten cost per kg in solid bulk form?
