Application Of W-Ni-Cu Alloy Bar
The W-Ni-Cu Alloy Bar is especially suitable for automobile counterweights. Drill one or more holes with a diameter of 25/64 or larger in the module, and then fill in the required number of tungsten alloy cylinders. Then insert a 3/8" long pin into the hole. The W-Ni-Cu Alloy Bar can also be processed into molds and various counterweights, such as speedboat counterweights, vehicle counterweights, aircraft counterweights, helicopter counterweights, marine counterweights, and tank counterweights.
