Properties of a Metal That Has Been Cold Worked

# data[].attributes.body
Metal becomes harder, stronger and has a better finish. The ductility of the metal decreases due to strain hardening thus making the metal more brittle.

Properties of a Metal That Has Been Hot Worked

# data[].attributes.body
Metal remains soft and ductile. It is weaker than cold working and has a poor surface finish due to surface oxidation.

# data[].attributes.body
Cold working is stronger. It has more strength, hardness and elastic limit that hot working. As well as a smoother finish.

Shaping metal while it is cold

# data[].attributes.body
- Hard
- Wear resistant
- Thermal and electrical insulators
- Rust resistant
- Chemically stable

# data[].attributes.body
Ceramics are a non-metallic material. They are generally made by taking mixtures of clay, powders, and water and shaping them into different shapes, such as pots or bricks.

# data[].attributes.body
Hot working is a process in which a metal is shaped under pressure at a high temperature

# data[].attributes.body
- Cheap
- Naturally non-stick
- Retains heat
- Long lasting

Cast iron is the oldest ferrous(containing or consisting of iron) metals used in construction and outdoor ornament. It is hard, brittle, non-malleable. The most common form is grey cast iron, but there is white cast iron. It has superior tensile strength and malleability.

# data[].attributes.body
- Stain and corrosion resistant
- Resists chemical and heat damage
- Even thin layers are extremely strong
- Higher ductility

# data[].attributes.body
Stainless steel is a form of steel containing chromium, resistant to tarnishing and rust.

# data[].attributes.body
- Light
- Easily shaped
- Strong
- Inexpensive

# data[].attributes.body
-Tensile Strength

The ability of a material to stretch without breaking or snapping.

-Ductile

The ability of a material to change shape (deform) usually by stretching along its length.

-Malleable

(of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking.

-Brittle

Hard but liable to break or shatter easily.
