Product Introduction
Product Overview
Titanium bolts are high-performance fasteners manufactured from pure titanium and titanium alloys. With a density of only 4.51 g/cm³, titanium fasteners offer an excellent strength-to-weight ratio and outstanding corrosion resistance.
Titanium fasteners are widely used in industries where weight reduction, reliability, and long service life are critical, including aerospace, marine engineering, automotive racing, and high-end industrial equipment.
Material Grades
Commonly produced titanium materials include:
Gr2 – General corrosion-resistant applications
Gr5 (Ti-6Al-4V) – High strength structural applications
Gr7 – Contains Pd, provides the best corrosion resistance (higher cost)
Gr12 – High-temperature and corrosion-resistant environments
Customized material grades are also available upon request.
Standards
Manufactured according to latest DIN and ISO standards
Non-standard customized fasteners available
