This product is professional Grade 9 titanium alloy seamless tube, specially customized and produced for high-end bicycle frame manufacturing, custom handmade bike frames, mountain bike and road bike structural frame parts. We only use primary original industrial titanium alloy ingot as raw material, 100% pure new material, no recycled scrap, no mixed impurity alloy, no secondary recycled smelting material.

The chemical composition of each batch is strictly tested and fully compliant with international Grade 9 titanium alloy industry standards. The internal metallographic structure of the tube body is uniform and dense, without segregation, without internal pores, without inclusions and without hidden cracks.

Adopting one-piece hot rolling and cold drawing integrated seamless forming process, no intermediate welding seam on the whole pipe body. Every single tube is inspected one by one before entering the warehouse, including appearance full inspection, size sampling inspection, straightness correction check and material composition recheck.

The overall quality is stable, reliable and completely suitable for high-standard bicycle frame load-bearing structural parts, avoiding hidden dangers such as frame fracture and safety failure caused by poor material quality.

Our Grade 9 bicycle frame titanium tube adopts advanced industrial seamless integral forming production technology, which fundamentally eliminates the weak risk of traditional welded pipe welding seam cracking.

• Outer wall finely polished with uniform smooth finish
• No drawing marks, scratch damage, oxidation black spots, or burrs
• Inner wall smooth and clean with no residual oxide scale or rough particles
• Uniform wall thickness with accurate roundness and minimal concentricity error
• Straightness controlled within high-precision industry range
• Ready for direct use in frame welding, shaping, and surface treatments

Grade 9 titanium alloy has excellent comprehensive mechanical properties, far exceeding ordinary aluminum alloy and low-carbon steel pipes used in standard bicycles.

• Ultra-high tensile strength and structural hardness
• Excellent low-temperature toughness and anti-fatigue performance
• Efficiently absorbs vibration and disperses structural stress
• No permanent deformation, bending distortion, or welding point cracking
• High safety coefficient with extended frame service life
• Ideal for mountain bikes, road racing bikes, and cross-country gravel bikes

Low density and high specific strength are the core competitive advantages of Grade 9 titanium bicycle frame tubes.

• Significantly lighter than steel and aluminum alloy frames
• Reduces rider physical consumption during long-distance riding
• Improves acceleration sensitivity and handling performance
• Natural strong corrosion and oxidation resistance
• No rust, corrosion, discoloration, or peeling in harsh environments
• Minimal maintenance requirements with reduced after-sales costs
