This is the Hot Rod of Pinewood Derby Weights! It is 1” in diameter & 2.6 oz. solid tungsten with a slot perfect for working your weight in around the rear axle for aggressively rear weighting your car. Putty or 1/4″ cubes can be added in the slot for additional weight.
Due to its very high density Tungsten is an excellent weighting material for pinewood derby cars. Only gold, platinum, and a few other rare and expensive metals have a similar density. 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. Also tungsten is completely non-toxic and environmentally friendly.
DERBY 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. This allows us to make very high density, precision weight and sized products for all forms of Pinewood Derby Construction. You will find not only is Derby Worx tungsten the highest density available but it is finish polished for the very best fit and appearance.
