GR2 Titanium sheets

Grade 2 Titanium Sheet



Product Description

Grade 2 Titanium Sheet

CP (commercially pure) grade 2 titanium sheet is primarily used in aerospace ducting applications, since it does not have the strength for most hydraulic applications. This alloy is also widely used in power generation, chemical processing and medical applications.
Standard: ASTM F67, ASTM B265, AMS 4905, AMS 4907.
