'''Alusil''' as a hypereutectic aluminium-silicon alloy (AlSi17Cu4Mg) contains approximately 70% aluminium and 30% silicon.<ref name=KSPG-AG>{{cite web|title=ALUSIL - Cylinder Blocks for the new Audi V6 and V8 SI engines|url=http://www.kspg-ag.com/pdfdoc/kspg_produktbroschueren/a_audi_zkg_e.pdf|format=PDF|work=KS Aluminium-Technologie AG|publisher=KSPG-AG.com|date= |accessdate=13 January 2010}}</ref><ref name=finishing.com>{{cite web|title=What is Alusil coating?|url=http://www.finishing.com/3600-3799/3605.shtml|work=finishing dot com|publisher=finishing.com|accessdate=13 January 2010}}</ref> This alloy was created in 1927 by Schweizer & Fehrenbach<ref name=Rheinmetall>{{cite web|title=Rheinmetall's tradition of automotive excellence|url=http://www.rheinmetall-detec.de/index.php?lang=3&fid=3397|work=Rheinmetall Defence|publisher=Rheinmetall-Detec.de|month=January|year=2006|accessdate=13 January 2010}}</ref> of Baden-Baden Germany and further developed by Kolbenschmidt.<ref name=finishing.com/>

The Alusil aluminium alloy is commonly used to make linerless aluminium alloy [[engine block]]s.<ref>{{cite web|title=High-performance engine blocks for tomorrow’s challenges|url=http://www.kspg-ag.de/index.php?lang=2&fid=444#11|work=Kolbenschmidt Pierburg AG|publisher=KSPG-AG.com|date=12 September 2005|accessdate=13 January 2010}}</ref> Alusil, when etched, will expose a very hard silicon precipitate. The silicon surface is porous enough to hold [[motor oil|oil]], and is an excellent bearing surface. [[BMW]] switched from [[Nikasil]]-coated cylinder walls to Alusil in 1996 to eliminate the corrosion problems caused through the use of petrol/gasoline containing sulfur.

Engines using Alusil include:
