AC4B is the aluminum with the combination of main alloy 7-10% Si and 2-4% Cu. At present, metal matrices and ceramic reinforcement as composite materials for different properties. You must be aware of popularity of Aluminium due to its lightweight, ductile, and low melting point.
Here we will be looking in to the important characteristics for Aluminium AC4B. Firstly, we will look the method for AC4B composition.
| Element | Al | Si | Fe | Cu | Mg |
| % | 86.5 | 7.65 | 1.01 | 2.51 | 1.05 |
Characteristics of Aluminum AC4B:
- Aluminum AC4B can be fabricated using a stir casting method.
- The density value of AC4B material is highly influenced by the percentage of porosity and shrinkage formed within each material.
- The material able to increase tensile strength.
- The hardness for AC4B aluminium material can be optimally increased.
- Pure AC4B alloy metals can be helpful in increasing the impact strength.
- The pure form of Aluminum AC4B metal material can be formed by the absence of B4C and enhancer agent such as Mg, Sr, and Al-5 Ti-1 B.
- In the dispersion strengthening mechanism, hardness and tensile strength of aluminum can be increased through Si3N4 particles.
