Zinc is classified as a
non-ferrous metal because it
does not contain iron (Fe) and does not rust like ferrous metals.
Key Properties of Zinc:
·
Corrosion-resistant: Commonly used for
galvanizing steel to prevent rusting.
·
Low melting point (419.5°C): Suitable for
die-casting applications.
·
Lightweight & Malleable: Used in
alloys like brass (copper + zinc).
