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:
"Each Tungsten Bar is equivalent in weight and size to five of the 1/4 inch tungsten cubes. Tungsten Bars greatly simplify installing weight as fewer items need to be glued into the body. Tungsten putty, or smaller tungsten parts can be used for making weight adjustments. "

How to Use this Product

Tungsten Bars can be easily used for pinewood derby car weighting by drilling a series of 1/4 inch deep holes in the bottom of the car and then using a chisel or sharp knife to clean out the pocket. Since the Tungsten Bars are very hard, do not plan to cut off or drill out any extra weight. Instead, use an alternate method to make fine adjustments such as adding/removing tungsten putty, beads, etc.
