China Tungsten Pinewood Derby Car Slugs for Balancing Weight

Tungsten Pinewood Derby Slugs

Tungsten alloy cylinders can be easily used for car weighting by drilling one or more 25/64" or larger diameter holes into the block and then inserting the desired number of cylinders. The hole can then be plugged with a piece of 3/8 inch dowel rod. The product also is manufactured as the parts of military defense, extrusion die, various counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.
Usually, tungsten alloy cylinder could be manufactured as the parts for military applications, extrusion die and various kinds of counterweights.
