  Aluminum legeringer for støbning (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

Aluminum Alloy and its Recommended end use
p1
LM 0 Alloy suitable for Sand Casting, components for Electrical, Chemical and Food Processing Industries.
LM 2 One of the two most widely used alloys for all types of die-castings.
LM 4 The most versatile of the alloys, has very good casting characteristics and isused for a very wide range of applications.
  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.
LM 21 Generally similar to LM 4M in character and application but better machinability and proof strength.
LM 22 Used for chill castings requiring good foundry characteristics and good ductility. Requires heat treatment.
LM 24 Suitable for large, intricate and thin walled castings in all types of moulds, also used where corrosion resistance or ductiity is required.
LM 25 Suitable where good corrosion resistance combined with thermal properties are required. Strength is attained by heat treatment.
LM 26 Mainly used for pistons as alternate to LM 13.
LM 27 A versatile sand and chill cast alloy introduced as an alternative to LM 4 and LM 21.
LM 28 Piston alloy with lower coefficient of thermal expansion than LM 13. This alloy use requires special foundry technique.
LM 29 Same characteristics as LM 28 but with still lower coefficient of thermal expansion than LM 28.
LM 30 For unlined die cast cylinder blocks with low expansion and excellent wear resistance.
