MAL Series Aluminum Alloy Mini Cylinder

Differences between aluminum alloy cylinders and cast iron types:

The most obvious difference is in the weight and the relevant direction of action between the two. Cast iron: good heat resistance, not easily deformed. After a cast iron engine wears, maintenance is simple and low-cost. Aluminum alloy: light weight, fast heat dissipation; the light-weight aluminum alloy engine can effectively reduce engine weight and achieve relatively fuel-efficient operation, and is often used in smc thin cylinder.

The materials commonly used in engines are divided into two types. One is made of aluminum alloy, the other of cast iron.

Advantages of aluminum alloy: lighter cylinder net weight, better heat dissipation. The advantage of light weight makes operation more flexible. Theoretically, light weight leads to lower fuel consumption. The advantage of the cast iron cylinder block is relatively weak, which is that it is more rigid. If a cast iron engine cylinder block with high characteristic requirements is to be modified, it is certainly better than aluminum alloy.

Aluminum alloy has excellent heat dissipation performance that cast iron does not possess. As for cast iron: its deformation resistance is particularly strong; the cast iron of the finger cylinder assembly has a particularly large heat-bearing capacity, which aluminum alloy materials do not possess. Therefore, some high-end automobile brands, especially turbocharged engines, still use cast iron as their engine cylinder block material, for heat resistance and high deformation resistance.
