Melting Point of Common Nickel Alloys
The melting points of nickel alloys can vary widely depending on the specific composition of the alloy. Pure nickel has a melting point of 1,455 °C (2,651 °F). However, the addition of alloying elements, such as chromium, molybdenum, iron, and others, influences the melting point of nickel alloys.
The table below provides a comprehensive list of melting point values for common nickel alloys at one atmospheric (atm) pressure. (1 atm = 101,325 Pa)
