Tungsten Pinewood Derby Car Weights

Calling all Pinewood Derby Car Racers, shop Pur-Tungsten for the best pinewood derby car weights made!
We fabricate our weights from premium Tungsten, one of the densest elements on the planet. Tungsten is the best material for Pinewood Derby Car Weights because its density allows for perfect placement of weight. Tungsten gives you the density of solid gold at a fraction of the price.

Whether in the Cub Scouts, Boy Scouts, Girl Scouts, Earth Scouts, Adventure Guides, Pathfinders, Navigators, Pioneers, Royal Rangers, Alert Cadets, Columbian Squires, Trail Life, DeMolay, or any other forms of Scouting, we all love the Pinewood Derby! The Pinewood Derby gives us the chance to spend genuine quality time with our kids while also teaching them important lessons about safely handling tools, the physics of motion, the effects of friction and drag, the difference in density of materials, and the importance of design & execution. The other lessons we all learn are good sportsmanship, fair competition, teamwork, grace in the face of defeat, and if we are skilled and have a bit of luck, the thrill of victory!

The acceleration due to gravity is a constant. So, the more mass, the greater the force acting to accelerate your Pinewood Derby Car. This force is competing against the forces exerted by aerodynamic drag and friction, so you want as much mass as possible to increase the acceleration force.

Official Rules limit Pinewood Derby Cars to a maximum weight of 5 ounces. The density of tungsten allows you to put as much of that weight as possible in a smaller space than other metals. This allows you to keep the mass of your racer in the best position for your design and allows you to make your center of gravity lower than other metals. Tungsten gives you the density of gold at a fraction of the price.

Most Pinewood Derby Cars weigh between 1.5 ounces and 3.5 ounces (depending on design) without any added weights, so a Pinewood Derby Car may need up to 3.5 ounces of additional weight.
The heavier your car is, the faster it’ll be, but the location of that weight that makes the most difference. You can add small Tungsten weights to the wood body of the car, so long as it doesn’t exceed the total weight limit. The official weight limit is five ounces, but check the rules for your local contest to be sure. The typical placement for the center of gravity is 1/4-inch to 1-inch in front of the rear axle. Go too far forward and you’ll lose potential energy, too far back and your car will lift its front end. Tungsten is the best weight for this because it’s so dense, allowing for the most precise placement and tuning.

Give yourself or your child the best advantage by using our Tungsten Weights for your Pinewood Derby Car racer.

Pur-Tungsten offers tungsten pinewood derby car weights as plates, cubes, cylinders, and a convenient moldable tungsten putty made from tungsten powder combined with a polymer binder that works great to fine-tune your Pinewood Derby Car.
