Cooling Rate and Mechanical Properties of Aluminum Castings: Key to Optimizing Quality, Cost, and Delivery

The quality of aluminum castings is largely influenced by the “cooling rate” during the manufacturing process. This article details how the cooling rate affects the microstructure and mechanical properties such as tensile strength, elongation, and hardness. It explains the importance of cooling rate management, a key to high-quality aluminum casting procurement, with specific data and examples. Daiwa Aluminum Vietnam’s quality control system is also introduced.
