The process and application fields of aluminum ingots are as follows: ### Production Process - **Melting**：High-purity aluminum ingots or recycled aluminum products are put into a furnace and heated to a certain temperature to melt them. During this process, an appropriate amount of alloying elements such as copper, magnesium, and silicon are added to improve the properties of aluminum and form an aluminum alloy melt that meets specific requirements. - **Refining**：The melted aluminum alloy is refined to remove impurities and gases such as hydrogen and oxide inclusions, thereby improving the quality of the aluminum ingot. The refining methods mainly include gas refining, flux refining and filtration refining. - **Casting**：The refined aluminum alloy melt is poured into a pre-designed mold and solidifies and forms under natural or forced cooling conditions to obtain an aluminum ingot. Casting methods include gravity casting, pressure casting, and centrifugal casting. - **Processing**：The cast aluminum ingot is further processed by rolling, extrusion, forging, etc. to obtain the required shape and size specifications. ### Application Fields - **Construction Industry**    - **Door and Window Frames**：Aluminum ingots are light in weight, corrosion-resistant, high in strength and easy to process. The door and window frames made of them are aesthetically pleasing, have good sealing performance and long service life, and are easy to install and maintain.    - **Curtain Walls**：In modern architecture, aluminum ingots are used to make curtain wall frames, which can meet the design requirements of large spans and complex shapes, and have good thermal insulation, sound insulation and fireproof performance.    - **Roof and Wall Materials**：Aluminum roofing and wall materials have good waterproofness and weather resistance, can effectively resist wind and rain erosion, and are light in weight and have a small load on the building structure. - **Automobile Industry**    - **Body Structural Parts**：Aluminum ingots can be used to manufacture body structural parts of automobiles, such as engine hoods, doors, and trunk lids, which can effectively reduce the weight of the body, improve the fuel economy and power performance of the automobile, and also enhance the corrosion resistance of the body.    - **Engine Components**：In engine manufacturing, aluminum ingots are used to produce components such as pistons, cylinder blocks, and radiators, which have good thermal conductivity and mechanical properties and can ensure the normal operation of the engine.    - **Interior Parts**：The dashboard, seat frame, armrest and other parts in the interior of the automobile are also often made of aluminum products, which are both beautiful and durable. - **Electronics and Power Industry**    - **Wires and Cables**：Aluminum has good electrical conductivity and relatively low price, so it is widely used to manufacture wires and cables for power transmission and connection of electrical equipment.    - **Electronic Components**：Aluminum ingots are also widely used in the manufacture of electronic components, such as capacitors, heat sinks, and printed circuit boards, which can meet the requirements of heat dissipation, conductivity and lightweight of electronic components. - **Packaging Industry**    - **Food Packaging**：Aluminum foil is a thin sheet material obtained by rolling aluminum ingots. It has good barrier properties, corrosion resistance and flexibility, and is widely used in food packaging, such as beverage cans, food cling film, and chocolate packaging, which can effectively protect the quality and safety of food.    - **Drug Packaging**：Aluminum foil also has important applications in drug packaging, such as blister packaging and aluminum-plastic composite packaging, which can ensure the stability and effectiveness of drugs. - **Mechanical Manufacturing Industry**    - **Mechanical Parts**：Aluminum ingots can be used to manufacture various mechanical parts, such as gears, shafts, nuts, bolts, etc., which have good processing performance and mechanical properties and can meet the use requirements of different mechanical products.    - **Die Manufacturing**：In die manufacturing, aluminum ingots can be used to make some simple dies or parts of dies, which have the advantages of low cost and short manufacturing cycle.
