High Density 18g/cc Metal Tungsten Counter Weight Alloy Cylinder

Characteristics : Pine car weight/ density and hardness 17.75-18.35 

Main ingredient : W(85-97)% with the addition of nickel and copper or nickel and iron,etc.

Application : Tungsten alloy cylinders are the superior product for balancing and weighting cars.

Tungsten is 3.2 times heavier than no-lead weighting material often used on cars, thus it enables tremendous flexibility in the design of the car. Incremental it contain five 1/2 ounce cylinders, one 1/4 ounce cylinders, and two 1/8 ounce cylinders. Using the incremental cylinders, you can achieve any weight between 0 and 3 ounces in 1/8 ounce increments. Compared with square tungsten bar, tungsten alloy cylinder is more popular because machining and production is easier. It is more easier to take it from the mold after press which means less damage. Moreover, it is more suitable for further machining. 

Tungsten Cylinder Weights

Tungsten is a metal with one of the highest densities. Tungsten is 1.7 times more dense than lead, 2.4 times denser than steel, and 2.7 times denser than zinc. 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. Also tungsten is completely non-toxic and environmentally friendly. 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.

How to Use this Product

A Tungsten Round can be easily used for pinewood derby car weighting if the weight of the car body, wheels, and axles is less than 1.75 ounces. Drill a 1/8 inch diameter hole into the bottom of the car body, and then epoxy the Round into the hole.
