Ferrous Metals
Ferrous metals contain iron as their main component.
These metals are known for their strength and durability and are commonly used in construction, manufacturing, and other heavy industries.
Examples
1) Steel
An alloy of iron and carbon widely used due to its strength and versatility.
It comes in various forms, such as carbon steel, alloy steel, stainless steel, and tool steel.
2) Cast Iron
Contains more carbon than steel, making it hard and brittle.
Used in heavy-duty applications like engine blocks and machinery.
Properties
Magnetic: Most ferrous metals are magnetic, which is a useful property in many applications.
High Strength: They offer high tensile strength and durability.
Corrosion Prone: Generally prone to rusting and corrosion when exposed to moisture and oxygen, although stainless steel and other alloys are exceptions due to added elements like chromium.
Applications
Construction: Beams, girders, and reinforcing bars.
Automotive Industry: Engine parts, frames, and suspension components.
Tools and Machinery: Drill bits, cutting tools, and machinery parts.
Nonferrous Metals
Nonferrous metals do not contain iron.
These metals are generally more resistant to corrosion and are lighter than ferrous metals, making them ideal for applications where these properties are desirable.
Examples
1) Aluminum
Lightweight, corrosion-resistant, and highly conductive. Used in aircraft, packaging, and electronics.
2) Copper
Excellent electrical and thermal conductivity. Used in electrical wiring, plumbing, and electronics.
3) Zinc
Used for galvanizing to protect steel from corrosion.
4) Titanium
High strength-to-weight ratio and excellent corrosion resistance. Used in aerospace, medical implants, and high-performance engineering.
Properties
Non-Magnetic: Most nonferrous metals are non-magnetic.
Corrosion Resistant: Generally, more resistant to corrosion and rust.
Lighter: Often lighter than ferrous metals, which is advantageous in applications where weight is a concern.
Applications
Aerospace: Aircraft components and structures.
Electrical: Wiring, connectors, and circuit boards.
Packaging: Beverage cans and foil.
