Aluminum-based materials are metals or composites in which aluminum is the predominant constituent. They include aluminum alloys, in which aluminum is alloyed with elements such as magnesium, silicon, copper, zinc, manganese or lithium to achieve improved strength, hardness and temperature performance, and aluminum matrix composites in which ceramic or other reinforcing particles are embedded in an aluminum matrix. The common appeal of aluminum-based materials is their combination of light weight, strength and corrosion resistance.

Aluminum has a low density around 2.7 g/cm3 and, with a protective oxide layer, exhibits good corrosion resistance and formability. Strength and ductility are highly dependent on alloy composition and heat treatment. Popular alloy families include 2xxx (Al-Cu), 5xxx (Al-Mg), 6xxx (Al-Mg-Si) and 7xxx (Al-Zn-Mg). These alloys can be cast, rolled, extruded or forged to produce parts for various industries. Processing choices influence properties such as stiffness, fatigue resistance and thermal conductivity.

Primary aluminum production requires energy-intensive smelting and refining, but aluminum is highly recyclable, with recycled material retaining most of its properties and using substantially less energy than primary production. Applications range from aerospace and automotive structures to packaging (cans), construction components and electrical housings. Ongoing research aims to improve high-temperature performance, reduce weight further, and develop aluminum-based composites for wear, corrosion, and thermal management applications.
