Beta 21S
Description:
Beta 21S is a heat treatable, metastable titanium alloy developed as an oxidation-resistant, aerospace material and as a matrix for metal-matrix composites. It offers the good formability and weldability of a beta alloy, but with greatly improved oxidation resistance and creep strength. This alloy is known to have a resistance to aircraft hydraulic fluid, which is why it is often used in the aerospace industry.
Tensile Strength: 115,000-140,000 psi
Yield Strength: 110,000-135,000 psi
Elongation: 12%
Available in multiple sizes and diameters in wire, coil, strip, foil, ribbon.
