Import Bolts — Buy in Bulk from Supplier in China

Tipro International Co., Ltd manufactures Ti-6Al-4V alloy bolts with a tensile strength up to 140,000 psi and density of 0.16 lb per cubic inch, based in Xi'an, Shaanxi Province, China. This alpha-beta titanium alloy contains 6 percent aluminium and 4 percent vanadium by nominal weight, a composition developed originally for aerospace structural applications in the 1950s. The 140 ksi tensile strength figure corresponds to aged or solution-treated and aged condition, not the annealed state, which buyers must clarify when specifying heat treatment.

Ti-6Al-4V achieves its strength-to-weight superiority through a mixed microstructure of alpha (hexagonal close-packed) and beta (body-centred cubic) phases. Aluminium stabilises the alpha phase for elevated temperature strength, while vanadium promotes beta phase to improve forgeability and heat treat response. Typical yield strength in the aged condition ranges from 120,000 to 130,000 psi, with elastic modulus around 16.5 MSI (114 GPa), roughly half that of steel. This lower modulus means greater elastic deflection under load, a design consideration for stiffness-critical joints. The alloy's fatigue threshold and crack growth resistance outperform most steels in corrosive environments, provided surface integrity is maintained during manufacture.

Primary end-users include aerospace airframe assemblers, marine propulsion system builders, racing vehicle constructors, and medical implant manufacturers. These sectors value Ti-6Al-4V for specific strength, biocompatibility, and immunity to galvanic corrosion when coupled with carbon fibre composites. Xi'an hosts significant Chinese aerospace manufacturing, giving Tipro potential proximity to tier-one customers. Buyers should confirm with Tipro whether bolts are supplied with full material certification, NADCAP-accredited processing, or standard commercial inspection, as aerospace and medical applications demand markedly different quality documentation.

Tipro International Co., Ltd is located at P.O. Box 258, Number 25 Gaoxin Road, Hi-Tech Development Zone, Xi'an 710075, Shaanxi Province, China. Xi'an is a major centre for Chinese aerospace, defence, and titanium processing industries, with state-supported industrial infrastructure and multiple research institutes. The company's positioning in the Hi-Tech Development Zone suggests access to technology-focused policy support and skilled engineering labour.

The supplier profile shows a response rate of 0.00 percent and zero average response hours, indicating no platform-mediated buyer communication history. Trust tier is harbour, a baseline level without verification depth. No factory certification, ISO registration, or transaction record is disclosed. The source description claims ISO and SGS certification without specifying scope or certificate numbers. Buyers should independently verify any claimed accreditations through SGS's certification database and request Tipro's actual organisational certification documents rather than relying on listing assertions.
