Using Aluminum Alloy Casting is one of the best ways to achieve a strong and durable product. This material is also very affordable, making it an excellent choice for many projects. Whether you want to make a simple phone case or a more complex piece of machinery, using an aluminum alloy cast part is the perfect way to get the job done.
The as-cast microstructure consists of a minor set of bright precipitates and a set of coarse Al(Zn) dendrites. The eutectic region contains Si-rich particles that have precipitated in the dendrites of the Al(Zn) matrix. The dark semi-circular feature is a defect that results from shrinkage during solidification.
The simulated results were in agreement with the experimental results. The alloys exhibited good microhardness performance. They showed microhardness values two to three times higher than commercial alloys.
