Nimonic 80A/UNS N07080

Short Description:

NIMONIC alloy 80A (UNS N07080) is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available. NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves.

      Waspaloy/UNS N07001

      Waspaloy (UNS N07001) is a nickel-base age-hardenable super alloy with excellent high temperature strength and good corrosion resistance, notably to oxidation, at service temperatures up to 1200°F (650°C) for critical rotating applications, and up to 1600°F (870°C) for other, less demanding ,applications. The alloy’s high-temperature strength is derived from its solid solution strengthening elements, molybdenum, cobalt and chromium, and its age hardening elements, aluminum and titanium. Its strength and stability ranges are higher than those typically available for alloy 718.

      Kovar/UNS K94610

      Kovar (UNS K94610), a nickel-iron-cobalt alloy containing approximately 29% nickel and 17% cobalt. Its thermal expansion characteristics match those of borosilicate glasses and alumina type ceramics. It is manufactured to a close chemistry range, yielding repeatable properties which make it eminently suitable for glass-to-metal seals in mass production applications, or where reliability is of paramount importance. The magnetic properties of Kovar are governed basically by its composition and by the heat treatment applied.

      Nickel Alloy 20 (UNS N08020) /DIN2.4660

      Alloy 20 stainless steel is a super-austenitic stainless alloy developed for maximum corrosion resistance to sulfuric acid and other aggressive environments not suitable for typical austenitic grades.

      Our Alloy 20 steel is a solution for stress corrosion cracking that can occur when stainless steel is introduced to chloride solutions. We supply Alloy 20 steel for a variety of applications and will help in determining the precise amount for your current project. Nickel Alloy 20 is readily fabricated to produce mixing tanks, heat exchangers, process piping, pickling equipment, pumps, valves, fasteners and fittings. Applications for alloy 20 requiring resistance to aqueous corrosion are essentially the same as those for INCOLOY alloy 825.
