This allows us to make very high density, precision weight and sized products for all forms of Pinewood Derby Construction. Also tungsten is completely non-toxic and environmentally friendly.ĭERBY WORX tungsten products are made using a process called “ Sintering”, this is the process of compacting and forming a solid mass of material by heat and pressure without melting it to the point of liquefaction. Tungsten is approximately 1.7 times denser than lead and 3.2 times denser than the zinc (“lead-free”) weight often used on pinewood derby cars, thus it allows a tremendous amount of freedom in the car design especially for speed by allowing the builder to place a large amount of weight in a small, aerodynamic area. Make sure your axles are not bent at all and that your plastic wheels are sanded down to. Only gold, platinum, and a few other rare and expensive metals have a similar density. The most important aspect of creating a winning pinewood derby car is underneath. Putty or 1/4″ cubes can be added in the slot for additional weight.ĭue to its very high density Tungsten is an excellent weighting material for pinewood derby cars.
