TYPES OF MATERIAL

1. Metallics2. Polymers 3. Ceramics 4. Composites5. Other materials

CLASSIFICATION OF MATERIALS (METALS)

•Metals can be further classified as Ferrous & Non-Ferrous, some examples include;Ferrous Non-Ferrous

Steels Aluminium

Stainless Steels Copper

High Speed Steels Brass

Cast Irons Titanium

AluminiumCopperBrassStainless SteelHigh Speed steel

POLYMERS

• Poly means many and mer stand for unit • It is like chainlike molecule made up of smaller moleculer unit

(monomers )• Ex- Plastics, wood, elastomers • Themosetting plastics, thermosets

CERAMICS

• Ceramics are compounds of metallic and non-metallic elements, examples include;

• Oxides (alumina – insulation and abrasives, zirconia – dies for metal extrusion and abrasives)

• Carbides (tungsten-carbide tools)• Nitrides (cubic boron nitride, 2nd in hardness to diamond)

COMPOSITES

• A composite is a combination of two or more chemically distinct materials whose physical characteristics are superior to its constituents acting independently.

• Because of their high strength/stiffness to weight ratio they are widely used in the; • Aerospace industry• Offshore structures• Boats• Sporting goods

COMPOSITES

• Examples of composites include;• Reinforced Plastics• Ceramic-matrix• Metal-Matrix• Laminates

Kevlar, taffeta polyester sailsGlass reinforced plastic hull

Carbon reinforced plasticThrust chamber for rocketCombustion chamber of jet engine

Cylinder liningsCylinder liningsOuter skin panels & fuselage A380

OTHER MATRIALSProperty of Cast iron can be economically cast into complicated shapes capacity of damping out vibration resistance to wear , abrasion and corrosion machined easily high compressive resistance brittle and has no plasticity

VARIOUS TYPE OF CAST IRON

1) Grey CI 2) White CI 3) Malleable CI 4) Chilled CI
