How Are INCOLOY Materials Made?
Alloy is made through the process of alloying, which involves combining two or more metallic elements, including at least one metal, in precise proportions. This can be achieved by either mixing molten metals or metal powders. The metals used in alloys can vary widely, such as copper, aluminum, iron, nickel, titanium, and many others. Additionally, non-metals like carbon and silicon can also be incorporated into the alloy composition. The desired elements are melted or mixed together under controlled conditions to ensure the desired alloy composition and properties are achieved.
