Alusil as a hypereutectic aluminium-silicon alloy (EN AC-AlSi17Cu4Mg / EN AC-48100 or A390) contains approximately 78% aluminium and 17% silicon.[1][2] This alloy was created in 1927 by Schweizer & Fehrenbach[3] of Baden-Baden Germany and further developed by Kolbenschmidt.[2]

The Alusil aluminium alloy is commonly used to make linerless aluminium alloy engine blocks.[4] Alusil, when etched, will expose a very hard silicon precipitate. The silicon surface is porous enough to hold 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.
