Titanium Grade 1 is the highest purity grade commercially available. The mechanical properties of titanium are greatly influenced by oxygen, nitrogen, hydrogen and iron. They increase the material's hardness, tensile strength and yield stress while simultaneously reducing elongation. Additionally, hydrogen triggers embrittlement that's its amount is kept as low as possible. Pure Titanium Grade 1 contains the lowest oxygen, hydrogen and iron levels, producing the most formable grade of the four ASTM commercially pure grades. Titanium Grade 1 should be used where maximum formability is required such as in dome loudspeaker, bursting discs and plate type heat exchangers. Its excellent cold deformability allows Lamineries MATTHEY SA to produce very thin strip, to approximately 5 microns.

It exhibits excellent corrosion resistance in highly oxidizing to mildly reducing environments, including chlorides. It has good impact properties at low temperatures. In addition, Titanium Grade 1 can be easily welded, machined, cold worked and hot worked. It is nonmagnetic.

Typical uses
Dome loudspeaker, bursting discs, medical devices, plate type heat exchangers, detector windows, windows for electron beam, etc.
