Inconel 625 (UNS N06625, Alloy 625, W.Nr. 2.4856) is a highly popular nickel-chromium alloy known for its exceptional properties, including high strength, excellent fabricability, and remarkable corrosion resistance. The strength of Inconel 625 is attributed to the reinforcing effect of molybdenum and niobium on its nickel-chromium matrix. As a result, it does not require precipitation hardening treatments. This unique combination of elements also provides superior resistance to various highly corrosive environments and high-temperature effects such as oxidation and carburization. Inconel 625 can effectively perform within a wide temperature range, from cryogenic temperatures up to 1800°F (982°C).

UNS N07718 (Alloy 718, W.Nr. 2.4668, Inconel® 718)is an exceptional alloy renowned for its remarkable combination of high strength and corrosion resistance. This age-hardenable alloy achieves its impressive properties through the strategic addition of niobium, titanium, and aluminum. With a temperature suitability ranging from -423°F to 1300°F, it demonstrates outstanding welding characteristics, including remarkable resistance to post weld cracking. Moreover, the ease and cost-effectiveness of fabricating Inconel 718, coupled with its exceptional tensile, fatigue, creep, and rupture strength, have made it a material of choice across a diverse range of applications."

UNS N04400 (also known as Alloy 400, W.Nr. 2.4360, or Monel® 400) is a single-phase, solid-solution alloy that achieves hardening primarily through cold working rather than heat treatment. It exhibits high strength and toughness across a broad temperature range and demonstrates exceptional resistance to various corrosive environments. Monel 400 retains excellent mechanical properties even at subzero temperatures, with strength and hardness increasing while maintaining ductility and impact resistance. Unlike many ferrous materials, it does not undergo a ductile-to-brittle transition even when exposed to the extremely low temperatures of liquid hydrogen.

UNS N05500 (Alloy K-500, W.Nr. 2.4375, Monel® K-500) is a precipitation-hardenable nickel-copper alloy with a low magnetic permeability. It exhibits strong non-magnetic characteristics across a broad temperature range, including subzero conditions. This alloy shares similar corrosion resistance with Monel 400 but offers the added benefits of enhanced strength and hardness. The increased properties are achieved by incorporating aluminum and titanium into the nickel-copper base and subjecting it to controlled heating conditions, resulting in the precipitation of submicroscopic particles of Ni3 (Ti, Al) throughout the matrix.

UNS N06075 (Alloy 75, W.Nr. 2.4951, Nimonic® 75) is an 80/20 nickel-chromium alloy featuring controlled additions of titanium and carbon. Renowned for its elevated temperature strength, corrosion resistance, and outstanding mechanical properties, this alloy finds extensive applications across diverse fields. Currently, it is predominantly employed in sheet applications that demand both oxidation and scaling resistance, along with medium strength at elevated operating temperatures. Furthermore, Nimonic 75 is easily fabricated and weldable.

UNS N07080 (Alloy 80A, W.Nr. 2.4631, Nimonic® 80A) is a nickel-chromium alloy that can be wrought and age-hardened. Strengthened through the addition of titanium, aluminum, and carbon, this alloy is designed for use in environments with temperatures reaching up to 815°C (1500°F). The manufacturing process involves high-frequency melting and casting in air for forms that will undergo extrusion.

UNS N07090 (Alloy 90, W.Nr. 2.4632, Nimonic® 90) is a wrought nickel-chromium-cobalt-based alloy, enhanced with titanium and aluminum for added strength. Designed as an age-hardenable, creep-resistant alloy, it excels in service at temperatures reaching up to 920°C (1688°F). The alloy boasts high tensile strength and exceptional resistance to creep, demonstrating good oxidation and corrosion resistance within the range of 815~870°C. Additionally, it exhibits high fatigue strength, along with favorable formability and weldability, even under the stress of repeated cold and heating cycles.

UNS N07263 (Alloy 263, W.Nr. 2.4650, Nimonic® 263) stands out as a nickel-based superalloy celebrated for its outstanding strength, resistance to high temperatures, and impressive corrosion resistance. Specifically crafted for situations that require both elevated strength and oxidation resistance, Nimonic 263 presents a harmonious combination of mechanical properties and thermal stability. Additionally, this alloy showcases commendable weldability, allowing for the construction and connection of components through diverse welding techniques.
