Aluminum Materials

Aluminum Materials
We are familiar with international standards, and can provide material choice recommendations.
   Wrought Aluminum Alloys (those that may be shaped by extrusion, rolling, drawing, or forging).
  Wrought alloys are the most widely used in aircraft construction as well as building industries.
   Wrought alloys are divided into two classes-nonheat treatable and heat treatable. Alloys 6061-T6 is used widely.

  Aluminum Alloy For Casting (suitable for casting in sand, permanent mold, and die castings)
A356 is the most popular. A380 aluminum alloy is also widely used for casting general-purpose die castings.
 It has good mechanical properties and is used in hundreds of applications including air brake castings, gear cases and air-cooled cylinder heads.
We are also familar with other frequently used materials such as A390, A383, A413, AlSi10Mg, ADC-12, ADC-14, LM4, LM6, LM9.

  Strength and Hardness can be grately incresed by Heat Treatment.
LM 5 Suitable for Sand and Chill Castings requiring maximul corrosion resistance i.e.castings of marine application.
LM 6 Suitable for large, intricate and thin walled castings in all types of moulds, also used where corrosion resistance or ductility is required.
LM 9 Used for allplications especially low pressure die casting requiring the characteristics of LM 6 with higher tensile strength after heat treatment.
LM 12 Mainly used for sand and chill castings requiring high strength and shock resistance. Requires special foundry techniques and heat treatment.
LM 13 Mainly used for piston and applications where thermal stresses are more. This alloy can witstand higher termperatures and loads.It has good wear resistance properties and machinability. Requires heat treatment.
LM 16 Suitable where high mechanical properties are desired in fairly intricate sand and chill castings. Requires heat treatment.
LM 20 Mainly used for pressure die casting. Similar to LM 6 but with better machinability and hardness.
