With the development of science and technology and the depletion of land resources, human exploitation and utilization of the sea has been put on the agenda. Titanium tubes have excellent corrosion resistance to seawater and are widely used in the fields of seawater desalination, ships, ocean thermal energy development and seabed resources exploitation.

Due to their own characteristics, titanium and titanium alloy have unique advantages in the application of ships and Marine equipment, so they are widely used in nuclear submarine, deep submersible, atomic icebreaker, hydrofoil, hovercraft, minesweeper, propeller, seawater pipeline, condenser, heat exchanger and other Marine engineering supplies.

At present, titanium used in ships is very small, accounting for less than 1% of the total weight of ships, and the field of spare titanium and titanium alloy for ships and Marine tooling has great potential for development. In addition, in the aspect of seawater desalination and coastal power station, due to the huge market demand of seawater desalination and coastal power station, if the cost of titanium alloy can be further reduced and the product quality and stability can be improved, the market application prospect of titanium will be very broad.

Titanium with its light weight, high strength characteristics in the application of sports goods, from the earliest tennis racket, badminton racket gradually expanded to golf head, clubs and racing cars, etc. Sport and leisure accounted for 13% of total consumption in 2008, with more than 1,000 tons of titanium used in golf heads and clubs alone. The light weight of titanium is also applied to the eyeglass frame, and titanium is not easy to allergy with the skin, and the surface of titanium can be anodized with gorgeous color, so it has been applied to the eyeglass frame since the early 1980s.
