Iron alloys containing high amounts of carbon (usually over 2%). They flow easily when melted, making them excellent for complex cast shapes like engine blocks. Non-Ferrous Metals (No Iron)

Controlling the mechanical properties of metals by altering their structure through alloying, heat treating, and mechanical working.

Metals play a different game. In a metal, the atoms exist in a "cloud" of shared, mobile electrons. This is often visualized as "metallic bonding." Imagine a lattice of atoms swimming in a sea of electrons.

The text primarily refers to the authoritative guide published by ASM International , currently in its Second Edition edited by Arthur C. Reardon . This resource is designed to explain the physical and chemical behavior of metallic elements without requiring a degree in materials science or engineering. Core Principles & Concepts
