Aerospace & Commercially Pure Titanium
Cascadia titanium rings and wedding bands are available in the two most common grades of titanium: Aerospace Grade 5 (Ti 6Al/4V alloy) and the Commercially Pure (CP Grade 2).
Either grade makes an attractive, lightweight, extremely durable ring. Both grades are nickel free and won't provoke skin allergies.
Aerospace Grade 5 is the most common grade. It is the workhorse of the titanium industry. Grade 5 titanium is an alloy (90% titanium, 6% aluminum, 4% vanadium) and is harder than CP grade, with a tensile strength of over 130,000 psi. Grade 5 is tougher because of its greater hardness and alloy composition. When anodized, aerospace grade titanium colors are slightly more vibrant than CP grade titanium colors.
CP Grade 2 is 98.99% pure, unalloyed titanium. This grade is softer than the Aerospace Grade 5, (but still harder than gold) and has a tensile strength of over 40,000 psi.
You may order your titanium ring in either grade - the cost is the same.
