Ti 6Al/4V (Titanium Grade 5) is the most widely used of all the alpha-beta titanium alloys accounting for more than 50% of total titanium usuage. It is typically used in the annealed condition, at service temperatures through 400°C (750°F). Ti 6Al/4V is welded with matching or with ELI filler wire. Ti 6Al/4V is significantly stronger than commercially pure titanium while having the same stiffness and thermal properties excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in CP Ti. Amongst its many advantages, it is heat treatable. This grade is an excellent combination of strength, corrosion resistance, weld and fabricability. In consequence, its uses are numerous such as for military aircraft or turbines. It is also used in surgical implants. Generally, it is used in applications up to 400°C to improve ductility and toughness in cold-worked condition. Please note that we have a minimum order value of £10,000.

Alloy 718 was initially developed for the aerospace industry but its excellent strength and corrosion resistance were recognised by the oil industry and it is now widely used in this field also. Alloy 718 is a nickel-chromium alloy with additions of niobium & molybdenum which can be heat-treated to give high strength, good corrosion resistance, ease of formability and which can be welded with good resistance to strain age cracking. The alloy can be used at temperatures up to 700ºC. Alloy 718 for the oil industry is heat treated such that the hardness does not exceed 40HRC which is the maximum allowed by NACE MR-01-75/ ISO 15156: 3 to prevent stress corrosion cracking. Alloy 718 for aerospace and power generation is heat treated to give maximum strength and high creep resistance with typical hardness values exceeding 42HRC. The major applications are components for gas turbines, aircraft engines Please note that we have a minimum order value of £10,000.
