L-605™ is a nonmagnetic cobalt-based chromium-tungstennickel alloy that has excellent corrosion and oxidation resistance, and high strength at both room and elevated temperatures. Through work hardening, high strength levels can be obtained. L-605™ has a minimal heat treatment response, but can be used in the cold worked and aged condition. Applications include medical implant devices, springs, valves, and engine components for the aerospace industry. As a result of its high tungsten content, L-605TM is radiopaque, which is beneficial for implant medical devices, such as stents. Because of the alloy’s high work hardening rate, only minimal reductions can be taken before solution annealing will be required. L-605TM is very resistant to oxidation and scaling at elevated temperatures, and is nonmagnetic in all conditions. L-605™ is produced by vacuum induction melting followed by electroslag remelting (VIM-ESR), and as such, has a low nonmetallic inclusion level.

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.

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.

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. Nickel alloy tubes offer excellent corrosion resistance, high melting points and resistance to oxidationIn addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. Nickel based alloys have a higher ability to accept alloying elements in solid solution than other stainless steel or iron-based alloys. They cantherefore maintain higher metallurgical stability. The combination of high alloying with multiple elements can provide very good corrosion resistance in a wide range of environments while still maintaining good welding and forming characteristics. Please note that we have a minimum order value of £10,000.

Titanium for Implantable Medical Devices Ti 6Al/4V ELI sheet has found application in medical implants owing to its excellent biocompatibility, high strength, and MRI compatibility. In the cold rolled and annealed temper the material will not exhibit a continuous alpha network at prior beta grain boundaries or a continuous alpha case layer on the surface. Owing to the alloy’s high strength and low ductility, it is difficult to cold draw into finished shapes. Hot forming has been found to be effective.
