Tungsten is the best weight for pinewood derby cars because it is about half the length of an equivalent lead weight and about a third the length of Zinc weights. Therefore, tungsten allows you to add weight exactly where you need it on your car. You can also remove more wood from your car, giving you complete car design freedom.

Grade information about tungsten alloy rod
Tungsten nickel-iron alloys are extremely versatile and have become the main tungsten-based heavy alloy in use. For general applications, such as counterweights, balancing hammers and radiation shielding devices, sintered alloys are used directly; however, for applications requiring high mechanical properties, tungsten-nickel-iron alloys require deformation processing and heat treatment to achieve strengthening.
(1) Tungsten-nickel-iron alloys are mainly used in the manufacture of gyroscope rotors, guidance devices and vibration damping devices for aviation and spacecraft.
(2) Die-casting moulds, tool holders, boring bars and automatic watch weights for mechanical engineering.
(3) Armour-piercing bullet cores for conventional weapons, rivet heads and switch contacts for electrical products.
(4) In addition, it is also used for the manufacture of various shielding components against radiation, etc.
