What is Tungsten?
Tungsten is a metal with one of the highest densities. Tungsten is 1.7 times more dense than lead, 2.4 times denser than steel, and 2.7 times denser than zinc.
From Randy:
"Solid Tungsten! Most tungsten products are molded from tungsten powder using high pressure and heat. This process, known as "Sintering", typically results in a density of about 18.1 g/cc. However, our tungsten round is sliced from a solid rod of tungsten. So the round is the full tungsten density of 19.2 g/cc!"
How to Use this Product
A Tungsten Round can be easily used for pinewood derby car weighting if the weight of the car body, wheels, and axles is less than 1.75 ounces. Drill a 1-1/16 inch diameter hole into the bottom of the car body, and then epoxy the Round into the hole.
Since the Tungsten Round is very hard, do not plan to drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten putty, beads, etc. In the photo, 3/16 inch tungsten cubes would be used.
(1)3.25 ounce nominal weight - actual weight ranges from 3.22 to 3.28 ounces
