Products Description
ERTi-12, Titanium Grade 12 is a higher strength, formable, alloy than titanium grades 1 through 4. ERTi-12 contains molybdenum and nickel which increases the resistance to corrosion with a lower cost than adding palladium. This alloy is typically used in applications of chemical processing, heat exchangers, valves and pumps.
Tensile Strength: 65,300 psi
Yield Strength: 55,100 psi
Elongation at Break: 12%
Available in multiple sizes and diameters in wire and spool.
