Surface Roughness: Ra0.4
Tungsten alloy ball for fishing lure W90 produced by EJ Carbide , has a very low surface roughness and small friction coefficient,so it can move freely in the rubber fishing lure. The center of gravity of the whole fishing lure are changing with its movement, which makes the fishing lure more vivid and more like a real fish. At the meantime, the tungsten alloy ball for fishing lure has a density up to 16.9g/cm3, so that in the same weitht, the tungsten alloy weight balance ball are smaller than the other material ball, more in line with the weight balance requirements.
