Properties: Ti-5Al-2.5Al has good weldability and shows stability and oxidation resistance at elevated temperatures (600 - 1000^oF)

Applications:jet turbine compressor blades, ducting, and steam turbine blades. The alloy is a more difficult alloy to forge with a narrow forgeability range and greater yield loss.

Forms: This alpha alloy is available in bar, billet, castings, extrustions, plate, sheet, and wire

Applications: Chemical processing and storage - containers, heat exchangers, ducting, pumps,

Forms typically available: billet, bar, plate, sheet, strip, rod, wire, extrusions, tubing.

Applications: Excellent cold formability, 20-50% higher tensile properties than CP titanium grades. Primarily used in aircraft hydraulic systems.

Forms The alloy is available as wire, bar, sheet, seamless and welded tubing. ASME code approved.

Titanium Grade 11 is the equivilent of Grade 1 but with a palladium addition which imparts a significant improvement in resistance to general and localized crevice corrosion in a wide range of reducing acid environments, including chlorides, and where low pH and high temperatures above 83^oC to 260^oC are prevalent.

Applications: Chemical processing and storage - containers, heat exchangers, ducting, pumps, valves, fittings and auxiliary equipment.

Forms: typically available: billet, bar, plate, sheet, strip, rod, wire, extrusions, tubing.

Addition of 0.3% Mo and 0.8% Ni to titanium increases corrosion resistance at a lower cost than Pd (see Ti Grades 7 and 11). Higher strength than unalloyed Ti grades 1 - 4, yet still formable.
Microstructure: Equiaxed alpha, with acicular alpha, primarily in welds or heat-affected zones, small amounts of beta.
Applications: Chemical processing, in mildly reducing or variable oxidizing-reducing media - containers, heat exchangers, pumps, valves, pipes and fittings.
Forms typically available: billet, bar, rod, plate, sheet, strip and tubing.

Titanium Alloy Grade 2 is unalloyed titanium offering an excellent balance of strength and ductility. The material has good toughness and is readily weldable. This material is very corrosion resistant in highly oxidizing and mildly reducing environments.

Foms:The alloy is available as castings, wire, welded tube, pipe, plate, sheet, strip, forgings, bar, and billet.

Titanium Alloy Grade 17 is alloyed titanium offering optimum ductility and cold formability, with properties similar to Grade 1 and Grade 11.
Grade 17 is like Grade 11 but with lower palladium. The material is readily weldable. This material is very corrosion resistant in highly oxidizing and mildly reducing environments.
Forms:The alloy is available as castings, wire, welded tube, pipe, plate, sheet, strip, forgings, bar, and billet.

Applications: Applications requiring excellent fracture toughness and fatigue strength; aircraft, structural components, biomedical.. Biomedical implants.

Biocompatibility: Excellent, especially when direct contact with tissue or bone is required. Ti-6Al-4V's poor shear strength makes it undesirable for bone screws or plates. It also has poor surface wear properties and tends to seize when in sliding contact with itself and other metals. Surface treatments such as nitriding and oxidizing can improve the surface wear properties.

Titanium Grade 26 with (0.1Ru) has equivalent (similar) mechanical properties to those of Grade 2 titanium.
Ti-Grade 26 offers equivalent corrosion resistance to Grades 7 and 16 titanium, in mildly reducing acidic environments to pH's 1 and temps 200^oC.

Titanium Grade 27 with (0.1Ru) has equivalent (similar) mechanical properties to those of Grade 2 titanium.
Ti-Grade 27 offers equivalent corrosion resistance to Grades 7 and 16 titanium, in mildly reducing acidic environments to pH's 1 and temps 200^oC.

Ti-3Al-2.5V with Ru alloy is a near alpha alloy that is strengthened by cold working.

Ti-6Al-4V alloy is the most widely used titanium alloy of the alpha-plus-beta class, and is also the most common of all titanium alloys.
This modification incorporates extra low interstitials (ELI) and also has a ruthenium addition to enhance the corrosion properties.where moderate strength, good strength to weight, and favorable corrosion properties are required.

Applications: Airframe applications, milling, forgings A readily forgeable alloy that offers excellent combinations of strength, ductility, fracture toughness and high cycle fatigue strength. Typically used for critical aircraft structures, such as landing gear.
Forms typically available: Billet, bar and plate Typical heat treatment for this alloy: Solution heat treat: 28-56^oC below beta transus for a minimum for 30 mins, then water quench. Aging heat treatment: 482-593^oC for 8 hrs, air cool."
