Surface Roughness: Ra1.6um to  Ra3.2um

●Titanium Alloy Small Part: CT5 to CT6; CT4 is also possible for high precision feature on specific area.

●Titanium Alloy Big Part: CT6 to CT7.

●Stainless Steel Parts: CT4 to CT5 or Meets DIN 7168 Class M standard.

●The Suggested tolerance is achieved by using silica sol and middle melt point wax in casting process
