Which Metals Are Ferrous?

Ferrous metals have a high carbon content which generally makes them vulnerable to rust when exposed to moisture.Most ferrous metals are magnetic which makes them very useful for motor and electrical applications.

  1. Steel

    • Steel is made by adding iron to carbon which hardens the iron. Alloy steel becomes even tougher as other elements like chromium and nickel are introduced

  2. Carbon Steel

    • Carbon steel has a higher carbon content in comparison to other types of steel making it exceptionally hard.

  3. Alloy Steel

    • Alloy steels incorporate elements such as chromium, nickel and titanium to impart greater strength and durability without increasing weight. Stainless steel is an important alloy steel made using chromium.

  4. Cast Iron

    • Cast iron is an alloy made from iron, carbon, and silicon. Cast iron is brittle and hard and resistant to wear.

  5. Wrought Iron

    • Wrought iron is an alloy with so little carbon content it’s almost pure iron. During the manufacturing process, some slag is added which gives wrought iron excellent resistance to corrosion and oxidation, however, it is low in hardness and fatigue strength.

Which Metals Are Non-Ferrous?

  1. Aluminum

    • Aluminum is lightweight, soft and low strength. Aluminum is easily cast, forged, machined and welded. It's not suitable for high-temperature environments. Because aluminum is lightweight, it is a good choice for the manufacturing of aircraft and food cans.

  2. Copper

    • Copper is red in color, highly ductile, malleable and has high conductivity for electricity and heat.

  3. Lead

    • Lead is a soft, heavy, malleable metal with a low melting point and low tensile strength. It can withstand corrosion from moisture and many acids.

  4. Zinc

    • Zinc is a medium to low strength metal with a very low melting point. It can be machined easily, but heating may be required to avoid cleavage of crystals.

  5. Tin

    • Tin is very soft and malleable, ductile with low tensile strength. It's often used to coat steel to prevent corrosion.
