1. Introduction:
Titanium have low density,high strength,excellent corrosion resistance,and biological features,so titanium
is a good material for artwork and jewelrys.Titanium alloy balls have lower weight and biological features,
it is wildly used in body jewelry field.
2.Remark:
1. Surface roughness: Ra<1.6
2. Diameter tolerance: ±0.05mm
