Def: Alloy |
a substance having metalic properties which is composed of 2 or more elements and at least 1 metal. Alloys are mixtures of a metal with other metals or Non-metals. |
|
|
|
Ferrous Materials |
Those materials containing iron as their most important alloying element, usually the solvent. |
|
|
|
Types of alloy's |
1. Wrought iron 2. Cast Iron 3. Carbon and Low alloy steel 4. Alloy steel 5. Stainless steel |
|
|
|
Wrought Iron |
Properties: Ductile , can be hammered into complex shapes.
Other uses: Lifting Tackle, decorative work
Quick Chem: Very low carbon <0.008% carbon [C] |
Maluable |
|
|
Cast Iron |
Properties: Low melting point, easily cast Other uses: Machine castings, valves Quick Chem: High Carbon >2.0% Carbon [C] |
|
|
|
Carbon and Low Alloy Steel |
Properties: Good Strenght and ductility Other uses: Bridge girders, pressure vessels Quick chem: 0.20% Carbon [C] to 0.45% Carbon [C] (strenght +, ductility-, toughness-) |
|
|
|
Alloy Steel |
Properties: Many special prperties depending on alloy Other uses: Tools, gears, high strenght or high temperature uses, special applcations. Quick chem: 0.20% to 0.35% NI,Cr,Mn |
|
|
|
Stainless Steels |
Properties: Corrosion resistance Other uses: Chemical plants, pressure vessels, tubing Quick chem: very low carbon >12% Cr can either be Ferrous or Non-Ferrous |
|
|
|
Non-Ferrous Materials |
Those allowys in which iron is not significant alloying element. |
|
|
|
Common Non-Ferrous Metals |
1.Aluminum 2.Copper 3.Lead 4.Magnesium 5.Nickle 6.Sliver 7.Zinc |
|
|
