As they have good oxidation and creep resistance, super alloys can be commonly forged, rolled to sheet or produced in various shapes. Iron-base, nickel-base and cobalt-base alloys are the major types of super alloys. Nickel-base and cobalt-base super alloys may be cast or wrought based on its composition or application. The iron-base super alloys are generally wrought alloys with stainless steel technology. These alloys can be strengthened by precipitation hardening, work hardening and solid-solution hardening. The following section will provide a detailed description of Nichrome™, which can withstand temperature up to 1028ºC (1850ºF). Chemical Composition The following table shows the chemical composition of Nichrome™. Elements Content (%) Iron, Fe 21-25 Chromium, Cr 14-18 Manganese, Mn 1 max Silicon, Si 0.75-1.6 Carbon, C 0.15 max Sulfur, S 0.01 max Nickel, Ni Balance Physical Properties The physical properties of super alloy Nichrome™ are given in the following table.

Nichrome Wire Scrap refers to the waste or surplus material generated from nichrome wire, which is an alloy made primarily of nickel (Ni) and chromium (Cr). Nichrome alloys are commonly used in high-temperature applications, such as heating elements in electric furnaces, toasters, hairdryers, and industrial equipment. The wire scrap is produced when nichrome wire is cut, processed, or damaged during manufacturing or use, and it is typically collected for recycling.
