When choosing nickel alloys, it’s essential to consider their density and melting point. Density impacts the actual weight of the alloy, while the melting point determines the maximum service temperature. These are the most critical physical properties of alloys.
Given the complex compositions of superalloys, their densities and melting points can vary significantly. In this article, we will summarize the densities and melting points of Monel, Inconel, Incoloy, and Hastelloy alloys, providing a valuable reference for selecting the right alloy for your needs.
