Applications & Case Studies
Aerospace
The aerospace industry places extremely high demands on the strength-to-weight ratio and reliability of materials. Traditional aluminum alloys, while lightweight, lack corrosion resistance. Grade 5 titanium alloys, while strong, increase manufacturing costs during forming and welding. Grade 9 titanium plate offers an ideal balance between strength and workability, making it widely used in thin-walled components such as hydraulic and fuel lines, fuselage skins, and fixed brackets. It not only reduces aircraft weight but also reduces production complexity and maintenance costs.
Chemical & Petrochemical
Chemical equipment operates in acidic, alkaline, and chloride environments for extended periods, and stainless steel and nickel-based alloys often struggle to withstand long-term corrosion. Grade 9 titanium plate offers near-pure titanium corrosion resistance, while its higher strength allows it to withstand pressure and shock. It is suitable for critical components such as heat exchanger plates, reactor linings, and tank panels, ensuring stable operation and extending service life.
Marine & Desalination
The biggest challenges in desalination and marine engineering are pitting and crevice corrosion, especially in high-salinity and high-humidity environments. Grade 9 titanium plate offers long-term resistance to chloride ion attack while maintaining moderate strength, avoiding excessive structural thickening. Typical applications include evaporators, condensers, ship piping, and offshore platform components, providing high-reliability solutions for offshore and desalination systems.
Medical & Biomedical
Medical devices require not only biocompatibility but also machining accuracy and welding reliability. Compared to Grade 5, Grade 9 titanium plate is easier to form and is suitable for surgical instrument housings, fixation brackets, and non-critical load-bearing implants. It offers a balance of safety and ease of processing, meeting the performance and cost balance requirements of medical manufacturers.
Sports & Consumer Goods
In the sports and consumer goods sectors, users seek lightweight and durable products. Grade 9 titanium plate can withstand harsh outdoor environments while maintaining an aesthetically pleasing surface, and is commonly used in high-end bicycle frames, golf clubs, camping equipment, etc. It makes the product lightweight and durable while enhancing the brand's high-end image.
