Alloy Classification:
Ferrous Alloy:
- High Strength Low Alloy Steels(Fe+C+Niobium),
- Medium Alloy Nickel-Chromium Steels,
- Manganese Steels,
- High resisting Steels etc.
Nonferrous Alloy:
- Light Alloys like Aluminium, Magnesium, Titanium & Zinc
Alloys
- Heavy Alloys like Copper, Nickel & Cobalt Alloys
Aluminum Alloy
Pure Aluminium is weak, light & ductile, density 2.7 Mg/m3, E – 70GPa,
Strength 45-150 Mpa.
T (heat Treated)3003 – Aluminium –Manganese alloy – a wrought alloy in
which dispersion hardening takes place due to Al-Mn Intermetallic
Compounds; Strength can go up to 310 Mpa; Used for Kitchen Utensils,
Tubing, Corrugated Sheet; often small Magnesium is added for additional
strengthening for use in Coke Cans
T5454 Aluminium & Magnesium Alloys, another wrought alloy used for
welded applications like liquid Tanks & Pressure Vessels
T5182 used for Can cover
All of them have excellent corrosion resistance and can be used for Marine
Environments. Aluminium – Silicon alloy is one of the most popular Cast alloy, light weight but
shrink heavily, with 11.6% Silicon eutectic mixture is possible, used in Gear
Boxes, Radiators and such thin walled complex geometry
