Tungsten Beads - 1 ouncea
Pinewood Derby Weight
What is Tungsten?
The word "tungsten" literally means "a substance of high density", and is derived from the Swedish language, "tung", meaning "heavy," and "sten", meaning "stone." The name is appropriate as tungsten is a metal with one of the highest densities. In fact, tungsten is 1.7 times more dense than lead. Only gold, platinum, and a few other rare and expensive metals have a similar density.
Applications of Tungsten
Tungsten is completely non-toxic and environmentally friendly so it is gaining increased use in weighting applications where lead is not appropriate. For example lead has been banned in many streams, so tungsten is often substituted for lead weight on fishing flies. The high density coupled with the non-toxic nature makes tungsten an ideal metal for this application.
For similar reasons tungsten is a superior product for weighting pinewood derby cars. Tungsten is 3.2 times the density of the zinc ("Lead Free") weighting material often used on pinewood derby cars, thus it enables tremendous flexibility in the design of the car. Coincidentally, tungsten has been used by NASCAR for the metal roll cage and as frame ballast to lower the center of gravity of the race car.
How to Use this Product
Tungsten Beads are ~3/16 inch diameter spheroids. To keep your cost down, the belt is not removed and the beads are not polished. This does not affect the use of the beads as ballast weight. Your shipment contains 1 ounce of beads (approximately 29).
Tungsten Beads are typically used for fine-tuning the weight of a car. This is accomplished by drilling 3/16 inch holes in the bottom of the car, and then gluing beads into the holes.
