Aluminium ingots are solid blocks of pure aluminium metal that are produced through a process called smelting. This process involves heating aluminium ore, known as bauxite, to high temperatures in the presence of a reducing agent, such as carbon, to extract the pure metal. The molten aluminium is then poured into moulds to form ingots, which are allowed to cool and solidify before being removed from the moulds. Aluminium ingots are typically rectangular or trapezoidal in shape, and are commonly used as a raw material for further processing into various aluminium products. Aluminium ingots are highly valued for their light weight, corrosion resistance, and excellent thermal and electrical conductivity. They are used in a wide range of applications, including construction, transportation, packaging, and electrical engineering. For example, aluminium ingots can be processed into sheets, plates, foils, and extruded profiles for use in building facades, automotive parts, beverage cans, and electrical wiring. They can also be cast into complex shapes for use in aerospace components and other high-performance applications. One of the key advantages of aluminium ingots is their recyclability. Aluminium is one of the most widely recycled metals in the world, with a recycling rate of around 75% globally. This is because aluminium can be melted down and reused without losing its quality or properties. Recycling aluminium ingots not only conserves natural resources, but also reduces energy consumption and greenhouse gas emissions associated with primary aluminium production.
