High-Density Tungsten Spheres

Abstract

Two, four-inch-diameter, unalloyed tungsten spheres were machined and lapped to a sphericity of better than five microinches and a background surface finish of less than three microinches, peak to valley. The material used was a special, uniform-density, gas-pressure-bonded tungsten made specially for the job.
