GR2 GR5 Titanium Alloy Ball Dia 30mm Ti Solid Metal Ball Titanium Balls
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 balls have lower weight and biological features,it is
wildly used in body jewelry field.
