Grade C-6 Titanium vs. Grade C-5 Titanium
Both grade C-6 titanium and grade C-5 titanium are titanium alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 95% of their average alloy composition in common.
For each property being compared, the top bar is grade C-6 titanium and the bottom bar is grade C-5 titanium.
