How to choose the right titanium raw material?

Titanium Grade 1 is the most malleable of the commercially pure Titanium grades. As a result, the alloy is widely specified for the manufacture of plate heat exchangers.

Titanium Grade 2 is also a commercially pure alpha (α) alloy. Although not as strong as Ti 6Al-4V, Titanium Grade 2 has outstanding corrosion resistance against various aggressive media. For example, Titanium grade 2 is virtually immune to wet chlorine at 10°C – 80°C (0-0.02 mpy or 0.001 mm/y) and thus, used to make chlorine dioxide mixers, pipework and fasteners in modern bleach plants. It is specified based on its excellent corrosion resistance in environments that include: calcium chloride, cupric chloride, ferric chloride, various concentrations of acetic acid, high-temperature seawater, most organic media, and more.

Titanium Grade 5 is the most widely used of all Titanium grades. It is typically available in the annealed condition and is readily heat-treatable to increase strength, for a wide range of applications. As a general-purpose alloy, Ti 6Al-4V has a broad spectrum of desirable properties at temperatures around -210°C – 400°C. The alloy is the most widely used high-strength titanium. Grade 5 combines mechanical strength and low density 4.506g/cm³ with excellent corrosion resistance in many different environments. Grade 5 titanium is heat treatable (solution heat treatment plus aging) in sections up to 25mm and can be employed up to around 400°C.
