Tungsten is the Best Weight for Pinewood Derby Cars

Tungsten weights are dense and small giving you maximum car design flexibility while providing precise center of gravity weight placement for maximum speed

Why use Tungsten???

Tungsten is the best pinewood derby weight because it is about 1.8 times denser than lead (a heavy metal) and 3 times denser than zinc. 

To demonstrate, below is a picture of a tungsten cylinder (top) and a three segment zinc cylinder (below).

The single tungsten cylinder on top weighs .5 oz and is 7/16" long.
The bottom zinc cylinders weigh .7 oz and are 1 5/8" long.

Tungsten is best because it gives you four advantages:

  1. You can pack more weight in a smaller area giving you more flexibility in your car design.
  2. You can place weight exactly where you need to optimize center of gravity for maximum speed.(See weight placement in Winning Pinewood Derby Secrets)
  3. Tungsten can be purchased in various forms; small BB spheres, 3/8" cylinders, 1/4" cubes, or tungsten putty which is maleable so it can be easily added or removed at checkin
  4. Tungsten has the added advantage of being safe to handle because it non-toxic making it kid friendly.
  • Tungsten cylinder diameter is 3/8". Just drill a 3/8" hole and slide them in to hide them inside the car. Use wood putty or glue to seal the hole.
  • If you need to pack weights even tighter, use our Tungsten cube weights
