Very low oxygen content causes a significant increase in ductility and corrosion resistance particularly in strong oxidizing environments. It has optimum malleability and cold forming and high mechanical strength.

This type combines good corrosion resistance, good cold formability, and excellent weldability. It shows perfect balance between strength and ductility, and has low weight ratio.

It is stronger and less flexible than Grade 1 and 2. It has excellent resistance to corrosion in different environments. It has optimum ductility and cold formability, excellent weldability, and high mechanical strength.

In contrast to commercial types, this Grade has the highest tensile strength at the expense of a reduction in ductility. It has optimum ductility and formability of the cold and high mechanical strength. Perfectly weldable. It has good resistance to corrosion in different environments. Grade 4 is mainly used in the aerospace industry, where high strength is required.

Very good mechanical properties at increased temperature to 350°C – 400°C. This material has the ideal combination of mechanical properties: hardness, ductility, tensile strength. It is the most used titanium alloy. Grade 5 is well weldable, although heat treatment may weaken the microstructure as a result of high temperatures. Its high strength, light weight and corrosion resistance gives a wide range of applications.

It’s similar to alloy Grade 2, except that it contains from 0.12 to 0.25% palladium. This small addition gives resistance to crevice corrosion at a temperature below 250°C and a pH value > 1.

Titanium Grade 9 is also defined as Ti-3AL-2, 4V or simply Ti-3-2, 5. This alloy can be used at temperatures higher than commercial grades 1-4. It is used in industry and the aerospace industry.

Alloy Grade 23 is also known as Ti-6Al-4V ELI or simply Ti 6-4, ELI. Titanium Grade 23 is very similar to Grade 5, except that Grade 23 has less oxygen, nitrogen and iron. This makes that the alloy has higher plasticity and better resistance to cracking than Grade 5
