Introduction of hypereutectic Al-Si alloys

Controllable CTE

A family of hypereutectic Al-Si alloys with CTE in the range from 15.1ppm/℃ to 16.9ppm/℃.

Hypereutectic Al-Si alloys are available in stock:

AlSi20   Al-20%Si alloy;

AlSi25   Al-25%Si alloy;

AlSi35,F  Al-35%Si alloy;

AlSi35,O  Al-35%Si alloy.

The AlSi Alloys Are Not Casting Al-Si Alloys:

Aluminum-silicon Casting Alloys are differ from Baienwei Co.,Ltd AlSi alloys,the casting al alloys are polyphase materials of composed microstructure belonging to the Aluminum Association classification series 3xxx for aluminum silicon plus copper and/or magnesium alloys and 4xxx aluminum silicon alloys. 

Lightweight AlSi20~AlSi35 Alloys:

Ease of machinability, for instance, the cylinder liners can be achieved the desirable effect by lathe,milling or grinding machining.

Baienwei Hypereutectic Si-Al alloys'Specific Strength:

Specific strength is known as the strength-to-weight ratio (or strength/weight ratio);

It is used most commonly for comparing materials,for automobile applications,this means a lighter vehicle that consumes less fuel.
