Quality Checking






What is Aluminum Cylinder Block?

The aluminum cylinder block is an internal combustion engine’s part. It is being disposed of between the crankcase and the cylinder head. Aluminum cylinder blocks are the whole engine’s support structure. The parts of the motor are mounted itself or on the engine block that ensures its alignment.


Iron or Aluminum: Which Material is Best for Cylinder Block?

A construction material, aluminum, is less strong compared to cast iron. A long time ago, it was thought that aluminum cylinder block is much thicker than iron. However, it was discovered that a well-constructed aluminum cylinder block is almost as sturdy as an iron block.

Typically, using cast aluminum alloys give a reduction of 40 to 55% than the previously applied iron cylinder. Aluminum alloys have a higher cost than gray cast iron. Despite its cost, it reduces fuel consumption resulting in a permanent increase in the aluminum cylinder block proportion.


What is the Primary Use of Aluminum Cylinder Block?

In the late 1970, aluminum cylinder blocks is used in gasoline engines. In 2005, the demand for aluminum cylinder blocks reaches 50%. Up to now, it is essential in all gasoline and diesel engines.


What Are the Requirements of Aluminum Cylinder Block?

There are various requirements for aluminum cylinder block, such as:

Thermal Conductivity

The material of the cylinder block needs to test the temperature exceeding 150-200 °C. The cast aluminum alloys’ thermal conductivity is three times higher compared to gray cast iron. It ensures the efficiency of engine cooling system transmission.

Strength at Elevated Temperatures

The desired strength of aluminum cylinder block preserves at above 200 °C temperature. The greatest stresses may happen in the bolted cylinder head. Therefore, the material should resist the load from thermal expansion and crankshaft rotation of the cylinder.

Hardness and Strength at Room Temperatures

The hardness and strength of aluminum alloy material provide high build quality and good stock removal.

Fatigue Strength

The engine cylinder block is put through cyclic tensile stress in various temperature ranges. This kind of interval starts with negative temperature during winter. It ends at about 150-200 oC of elevated temperature. That’s why the fatigue strength of the cylinder materials is an important characteristic.

It is popular that the characteristics of any metal casting materials, such as aluminum and iron depend on the heat treatment and composition material. It also depends on the casting space and casting method.


What Are the Factors to Consider When Choosing Aluminum Casting Alloy for Cylinder Block?

The aluminum alloy casting is the complex casting production of cylinder blocks. It should be in accordance with the technical requirements, such as:

  • Good machinability
  • Low cost
  • Good casting properties
  • High strength in elevated temperatures

There are various factors to consider when choosing aluminum casting alloy for cylinder block, it includes:


The strength of the alloy is determined by its level, such as the allowable wall thickness. Therefore, aluminum casting alloy should carry out at the first designing stage of the cylinder block.

The strength of the aluminum casting alloy is the most preferred choice. However, they can have a high cost, shortcomings, insufficient strength, and low castability at elevated temperatures.


Most of the automotive aluminum cylinder blocks are made from alloys for technical and price reasons. It is based on recycled aluminum uses like aluminum alloys from aluminum scrap. For example, alloys EN AC-45000 (AlSi6Cu4) and EN AC-46200 (AlSi8Cu3).

Casting Properties

Aluminum alloy castability is increased with silicon’s increasing content. On the other hand, high-temperature strength is achieved through additives copper. It has a negative effect on aluminum alloy castability.

Additionally, the alloy, when molding is applied under high pressure, is being used with some Mn and iron. As a result, it prevents molten aluminum from sticking to a steel mold. Also, the increasing content of iron decreases the aluminum casting strength properties.

Sometimes, casting properties and price are not only the factors when selecting cast alloy. Some of its properties, such as wear resistance are also important.
