Sheet, strip Nimonic 263® - 2.4650 - alloy C-263

Company Avecglobal sells at affordable prices from manufacturers of sheet metal (sheet or tape), which is made of alloy Nimonic 263 (other names — Alloy C-263, 2.4650). The supplier is guaranteed timely shipment of products to any address specified by the consumer.

Composition and application

Nimonic 263 (Alloy C-263, 2.4650) is an aging-hardened nickel-cobalt-chromium-molybdenum alloy that was designed to maintain a high level of its performance after annealing and with very good strength properties after aging.

Nimonic 263 alloy products have excellent plastic viscosity over a wide range of temperatures, and are usually not subject to deformation cracking, which is characteristic of other hardening alloys of this type. The alloy is nonmagnetic. The limiting temperature range of application — according to the resistance of high-temperature corrosion — no more than 960 ° C, in combination with mechanical loads — up to 815 0 С.

The alloy Nimonic 263 (Alloy C-263, 2.4650) is characterized by an increased ability to form plastic in a wide temperature range. Electric welding of products from this alloy is possible using a suitable composite filler technology TIG and MIG.

This alloy combines properties that make it suitable for various components of aircraft turbines. From the alloy under consideration, various sealing elements as well as critical parts of gas power equipment are produced.

The chemical composition of the alloy Nimonic 263 (Alloy C-263, 2.4650), which meets the technical requirements of the standards UNS N07623 and AMS 5872, is presented in the table (nickel — the rest):
