NON FERROUS METALS PG 3.18 - 3.27

NONFERROUS METALS

ALUMINIUM

• Lightweight and 1/2 the weight of metal.
• Characteristics of aluminium gives it metal resistance to rust.
• However aluminium can be corroded easily by alkalis they attack the Oxide layer.

MAGNESIUM

• Magnesium is mainly used in alloy form.
• It is the lightest of the structural metals.
• Has one quarter less than other metals.

MAGNESIUM

• Can be extruded, forged, rolled, and machined.
• Best welded by GMAW for thin sections.

TITANIUM

• Titanium is usually in alloy form.
• Alloys are high strength light weight.
• And one half the density of steel.
• Titanium is a reactive metal.

ALPHA ALLOYS

• Strength and oxidation resistants from 600°F to 1,100°F

BETA ALLOYS

• Can contain vanadium, chromium, and Aluminium

BERYLLIUM ALLOYS

• Is a high strength light weight metal. It is only about 2/3 as heavy as aluminium.

COPPER & COPPER ALLOYS

• Copper is often used in nearly pure form for electrical and heat conductors
• Other bronzes are formed by alloying copper with aluminium, silicon, or Beryllium.

NICKEL AND ALLOYS

• A corrosion resistant metal.
• Used as an alloying element as well as for plating other metals.

HOT TIP

• The Statue of Liberty contains 179,000 pounds of copper.
• When copper oxidises it forms a blue green self protective coating.
