Products Description
Titanium Grade 5 is the most widely used titanium alloy, consisting of 6% aluminum, 4% vanadium, and balanced properties. It is the primary structural titanium plate material for civil and military aircraft due to balanced strength, lightweight, corrosion resistance and processability.
Ruihang is specialized in Grade 5 titanium products for more than 13 experience in domestic titanium industry. We have a warehouse in China Titanium Valley, with an annual titanium Grade5 plates/sheet storage capacity of over 100 metric tons. Sufficient stock supports quick order processing and prompt delivery arrangement.

FAQ about Titanium Grade 5 Plate for Aircraft
What surface quality requirements apply to aviation Grade 5 titanium plates?
- No cracks, inclusions, porosity, scratches, dents or oxidation layers on finished surfaces
- Uniform mill finish or pickled bright surface; heavy oxide scale must be fully removed
- Surface roughness Ra ≤3.2μm for machined structural surfaces
- 100% visual inspection + fluorescent penetrant testing (FPT) to detect micro surface defects
What non-destructive testing (NDT) is important for aircraft titanium plates?
- Ultrasonic Testing (UT): Detect internal voids, segregation and laminations inside thick plates
- Fluorescent Penetrant Inspection (FPI): Identify tiny surface cracks
- X-ray testing: Check tiny internal impurities All test reports are traceable for aircraft component certification.
How to store Grade 5 titanium plates to avoid defects before aircraft manufacturing?
- Store in dry, constant-temperature warehouse with humidity below 60% to prevent surface water staining
- Separate from carbon steel; use wooden or plastic spacers to avoid iron contamination.
- Cover plates with protective plastic film; avoid direct contact with dust, acid, alkaline chemicals
- Stack flat to prevent bending deformation; mark material heat lot number for traceability
Is Grade 5 titanium plate suitable for supersonic aircraft?
Yes for most structural parts. Ti-6Al-4V maintains stable performance under sustained flight temperature up to 400°C, matching the thermal load of Mach 2–2.5 aircraft. For hypersonic flight with surface temperature over 500°C, high-temperature titanium alloys will replace Grade 5 plates.
