Heat Treatment Process of Aluminum Alloy
Aluminum heat treatment is a controlled process that enhances the mechanical properties of aluminum alloys by modifying their microstructure. The most common heat treatment methods used for aluminum alloys include solution heat treatment, quenching, and aging. At Alucast Foundry, we provide high-quality heat treatment services.
1. Solution Heat Treatment
The first step in the aluminum heat treatment process is heating the aluminum alloy to a specific temperature (typically between 480°C and 540°C) to dissolve soluble elements into a solid solution. The material is held at this temperature for a defined period to ensure uniform distribution of alloying elements.
2. Quenching
Immediately after solution treatment, the alloy is rapidly cooled (quenched) using water, oil, or air. This step locks the alloying elements in place, creating a supersaturated solid solution that improves strength and hardness.
3. Aging (Natural or Artificial)
After quenching, the material undergoes aging to achieve the desired mechanical properties. There are two types of aging:
1. Natural Aging (T4): The aluminum alloy is left at room temperature for several days to gradually develop its properties.
2. Artificial Aging (T6 Heat Treatment): The material is heated to a lower temperature (120°C – 200°C) for a few hours, allowing precipitation hardening to take place. This method significantly enhances the alloy’s strength and is commonly referred to as T6 heat treatment.
Applications of T6 Heat Treatment:
The T6 heat treatment process is widely used in aerospace, automotive, and industrial applications where high strength, corrosion resistance, and durability are required. Components such as structural parts, engine components, and high-performance machinery often undergo this treatment.

MELTING FURNACE
We have two furnaces that can both melt and hold aluminum for casting. One furnace has a capacity of 250 kilograms, while the other can hold 350 kilograms. These furnaces help in maintaining a steady supply of molten aluminum for production. The melting process ensures that the aluminum reaches the right temperature for casting. Once melted, the metal stays in the furnace at a controlled temperature. This prevents it from cooling down too quickly before being poured into molds. The furnaces improve efficiency by reducing the need for frequent reheating. With these, we can produce high-quality aluminum castings consistently.
CASTING POURING AREA
The casting pouring area in Alucast Foundry is a critical zone where molten aluminum is carefully transferred into pre-heated molds to form high-quality gravity die cast components. This area is designed to maintain strict temperature control to ensure uniform filling of the die cavity, minimizing defects like porosity and cold shuts. Operators follow precise pouring techniques to achieve consistent metal flow, reducing turbulence and ensuring optimal material properties. Safety is a top priority, with protective gear and controlled environments to prevent accidents from molten metal handling. The pouring ladles are regularly maintained to avoid contamination and ensure smooth pouring operations.
CUTTING AREA
The cutting area is equipped with a large bandsaw cutting machine, capable of cutting castings up to 2.5 feet in width. This high-capacity machine ensures precise and efficient cutting, minimizing material waste and improving productivity. It is designed to handle heavy-duty aluminum castings with smooth and accurate separation of excess material. The robust blade system allows for consistent performance, reducing manual labor and improving workflow. Safety features such as operator shielding and controlled cutting speed ensure a secure working environment. This cutting setup plays a vital role in preparing castings for further machining and finishing processes.
FETTLING AREA
The fettling area is equipped with a belt grinding machine and multiple angle grinders for efficient casting fettling. The belt grinding machine ensures smooth surface finishing by removing excess material and sharp edges from the castings. Angle grinders provide flexibility for detailed fettling, allowing operators to reach complex areas with precision. These machines help improve productivity by reducing manual effort and enhancing the quality of finished components. Safety measures, including protective gear and dust extraction systems, ensure a secure working environment. This setup plays a crucial role in refining cast components before further processing.
