Titanium Technical Data

Commercially pure Titanium combines superior corrosion resistance with a high strength to weight ratio, making it a cost-effective solution to many design problems.

Corrosion Resistance

Titanium possesses excellent resistance to a wide range of corrosive environments, which can cause severe attack on other materials of construction. It is particularly resistant to oxidising media and the pitting, crevice corrosion and stress corrosion cracking mechanisms associated with solutions containing chloride ions.

Titanium has exceptional resistance to seawater, even to very high temperatures. For heat exchange and piping applications, this is further enhanced by excellent resistance to erosion and cavitation.

Welding

Titanium is not a difficult metal to weld, but strict precautions must be taken to guard against contamination. Fusion welding techniques must be aimed, therefore, at the exclusion of atmospheric contamination, by welding, argon, helium, or vacuum, following careful cleaning and edge preparation of the areas to be joined.

All heated surfaces, front and back, must be protected from exposure to atmospheric contaminants. MIG, TIG, plasma-arc, friction and electron beam processes are all suitable for titanium welding.

Titanium cannot be welded to other metals.
