Features
- ASTM B381 Titanium and Titanium Alloy Forgings conforming to the latest standard requirements for 39 grades of annealed forgings (page focuses on popular grades F-2, F-5, F-7, F-12).
- Superior strength-to-weight ratio combined with outstanding corrosion resistance in aggressive environments (chemical, marine, aerospace).
- Produced by multiple forging processes including open-die, closed-die, isothermal forging, and precision ring rolling for enhanced mechanical properties and dimensional accuracy.
- Excellent weldability, machinability, and fabricability across CP titanium and alloy grades.
- High ductility, toughness, fatigue resistance, and biocompatibility (especially Grades F-2 and F-7).
- Available in a wide range of custom forms: rings, disks, hubs, blocks, flats, forged shafts, bars (round/square/rectangular/hexagonal), billets, flanges, and complex shapes.
- Full NDE testing (UT/ET) and material certification (EN 10204 3.1 / 3.2) available for critical applications.
- Low density (4.51 g/cm³), non-magnetic, and stable mechanical performance after proper heat treatment.
Applications
- Aerospace structural components, engine parts, landing gear, and airframe forgings requiring high strength and lightweight performance.
- Medical implants, prosthetics, surgical instruments, and biocompatible devices (primarily CP titanium Grades F-2 and F-7).
- Chemical processing equipment and pressure vessels needing superior corrosion resistance (Grades F-2, F-7, F-12).
- Marine propellers, shafts, valves, and seawater-exposed components with excellent saltwater corrosion resistance.
- Power generation turbine blades, disks, and high-temperature rotating parts.
- Automotive and motorsports high-performance components such as connecting rods, valves, and suspension parts.
- Industrial rotating machinery, power transmission shafts, axles, and custom-machined structural forgings.
- Precision rings, disks, hubs, and blocks for critical assemblies after qualification and heat treatment.
