Ta1

Ta2

Ta3

The titanium content is high, and its mechanical properties and chemical properties Its performance is similar to that of stainless steel, its strength is not as high as that of titanium alloy, its plasticity is good, and it is easy to process and shape. Pressure and welding performance are good. in the atmosphere and sea water It has good corrosion resistance in such environments, and its oxidation resistance is stronger than stainless steel, but its heat resistance is lower.

Mainly used for stamping parts and corrosion-resistant structures with working temperatures below 350°C that are not subject to much force but require high plasticity. Components, such as aircraft frames, ship pipes, valves Doors, pumps, heat exchangers, distillation columns, cooling device, ion pump, compressor valve. Industry first Generally requiring high formability, use Ta 1, wear resistance and high strength The degree of use is Ta 3, and the most widely used is Ta 2.

     α

Ta4

It cannot be strengthened by heat treatment, it can only be strengthened by solid solution chemical, the room temperature strength is lower , but the high temperature

(500-600c) strength and creep pole

The limit is the highest. And tissue stability, antioxidant Good weldability, corrosion resistance and cutting resistance Good processability, poor stamping properties.

Mainly used for welding wire in China

Ta5

Ta6

Used for parts in corrosive media below 400°C, Such as aircraft frames, ship blades, etc.

Ta7

Used for forgings and parts below 500°C, for short-term use It can be used up to 900° and can also be used for ultra-low temperature components (- 253°), such as ultra-low temperature containers

Ta8

For parts used for a long time below 500°C, such as hair Engine compressor disc and blades.
