Description
Technical Parameters
Products Introduction
Titanium round bars are core semi-finished raw materials for aerospace structural, engine, landing gear and fastener components. Compared with steel, aluminum and superalloys, titanium alloys has an excellent combination of low density, high strength, high-temperature stability and superior corrosion resistance. The properties make them irreplaceable for civil airliners, military jets, helicopters, rockets and spacecraft.
Aerospace titanium round bars are strictly produced to aerospace specifications. All the aerospace grade titanium bars have full traceability, strict melting control and 100% non-destructive testing (NDT) to meet zero-failure flight safety standards.

FAQ About Grade 5 Titanium Bars for Aerospace
What aerospace components use Grade 5 titanium bars?
- Airframe structure: Wing joint forgings, fuselage connecting brackets, landing gear core shafts
- Aero-engine: Compressor blades, wheel hubs, valve stems, fastener blanks
- Auxiliary systems: Hydraulic pipeline joints, actuator shafts, undercarriage pin shafts
- Spacecraft: Rocket structural connectors, satellite support frames, launch vehicle fasteners
Can Grade 5 titanium bars be welded and machined for aerospace manufacturing?
- Machinable with dedicated titanium cutting tools; low cutting speed recommended to avoid work hardening and surface burning
- Good fusion welding performance ; welded joints retain over 90% base metal strength, widely used in aircraft assembly
- Avoid contamination with iron, copper during processing to prevent embrittlement.
How to store aerospace Grade 5 titanium bars to avoid defects?
- Store in dry, low-humidity warehouse; separate from carbon steel to prevent iron contamination
- Wrap with anti-rust paper or plastic film; avoid direct contact with moisture, salt and acid
- Stack with wooden spacers to prevent surface scratch damage
- Mark heat number, batch and material grade clearly for full traceability
