Alloying processes

Definition

Alloying processes refer to the techniques and methods used to combine two or more metals, or a metal with non-metals, to create an alloy with desired properties. These processes can enhance characteristics such as strength, corrosion resistance, and malleability, making the resulting material more suitable for various applications. In the context of native copper, understanding alloying processes is essential for recognizing how early metallurgists transformed basic materials into more advanced forms through experimentation and innovation.
