Product Details

Titanium 6-2-4-2 (6Al-2Sn-4Zr-2Mo) is an alpha-beta titanium alloy capable of being heat treated to higher strengths in greater section sizes that 6Al-4V. Widely used in forged components, 6-2-4-2 beta forged material has enhanced strength, ductility and a combination of good low-cycle fatigue and fatigue-crack growth resistance. This alloy is used in the intermediate compressor stages of turbine engines for disks and blades, seals and for airframe parts.

Titanium Alloy Grade 12 Ti-0.3Mo-0.8Ni Sheet and Plate

Titanium Grade 12 is similar to Grade 2 and Grade 3 except Grade 12 has the addition of Mo and Ni. These additions to Grade 12 offer a lower cost option than the Palladium bearing grades. Grade 12 has

Titanium alloy Grade 9 Ti-3Al-2.5V Sheet and Plate

Titanium Ti3Al2.5V (grade 9) or more simply known as Ti-3-2.5 is commonly grouped with the commercially pure grades due to it's ability to be cold rolled. The strength of Ti3al2.5V (Ti-3-2.5) falls be
