Controlled expansion AlSi alloys
Jun 24, 2016

AlSi alloy is a kind of low thermal expansion aluminum alloy.


  • If the thermal expansion of traditional aluminum alloy is high,it can replace traditional aluminum alloy;

  • It can replace some low thermal expansion materials, e.g.: KOVAR with relatively heavy weight;

  • It can replace the materials with low thermal expansion and high thermal conductivity but heavy weight, e.g.: copper-molybdenum, copper-tungsten and copper, while the weight of these materials is a problem;

  • It canreplace the standard aluminum alloy because of the higher stiffness.

  • If there is requirement of structure stability, it can be combined with the property of metals and ceramic materials and operated within some extent of temperature range.
