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
