Casting of light metals

NACE code 24.53, 'Casting of light metals', represents a crucial industry within the broader manufacturing sector. This industry is responsible for the production of a wide range of cast metal components, primarily using lightweight alloys such as aluminum, magnesium, and their derivatives. These cast products find applications across diverse industries, including automotive, aerospace, electronics, and consumer goods, making the casting of light metals a vital contributor to the global economy.

The casting of light metals typically involves several key production techniques. The most common method is sand casting, where molten metal is poured into a sand mold and allowed to solidify. Other techniques, such as die casting and investment casting, are also employed to achieve more complex geometries and tighter tolerances. Automated processes, including computerized numerical control (CNC) machining and robotic handling, have become increasingly prevalent in this industry to enhance efficiency and precision.

The casting of light metals relies on a range of inputs, including raw materials, machinery, and energy sources. The primary raw materials are light metal alloys, such as 24.42 Aluminium production, 24.45 Other non-ferrous metal production, and 24.51 Casting of iron. Specialized casting equipment, such as furnaces, molds, and automated handling systems, are also essential inputs for this industry. Additionally, the casting process requires significant energy inputs, typically in the form of electricity or natural gas, to melt and pour the molten metal.

The casting of light metals produces a diverse range of cast metal components, which are then utilized by various other industries. These outputs include automotive parts, such as engine blocks and transmission housings; aerospace components, like landing gear and structural elements; and consumer goods, including electronics casings and household appliances. The cast light metal products from this industry are often further processed or assembled by 25.11 Manufacture of metal structures and parts of structures, 29.32 Manufacture of other parts and accessories for motor vehicles, and 26.11 Manufacture of electronic components, among other related NACE codes.
