The Material Of Opportunity
Aluminum stands as one of the most essential metals in industrial usage, second only to steel. Its widespread applications span across various industries and everyday life, owing to its lightweight nature, high strength, and recyclability.
Described as ‘the material of opportunity,’ aluminum is experiencing rapid growth due to its unparalleled combination of properties. From exceptional strength and low weight to superb electrical and thermal conductivity, along with excellent formability and corrosion resistance, aluminum proves versatile in diverse design contexts and product applications.
Extracted from alumina via the Hall-Heroult process in smelters, aluminum originates from bauxite through the Bayer process in alumina refineries. Moreover, aluminum’s recyclability underscores its sustainability, requiring only a fraction of the energy for primary production.
The advantages of aluminum extrusion are manifold: It offers ease of fabrication over welding, presenting an economical solution with consistent cross-sections. As an excellent heat protector, aluminum is easily bonded with adhesives, making it a preferred choice in construction projects.
Furthermore, aluminum extrusion machines boast cost-effectiveness, contributing to their widespread adoption

Aluminium alloys and tempers
Emirates Extrusion produces most of customer requirements in its facilities using alloys 6061 and 6063 with T4, T5 and T6 tempers.
6061 is a precipitation hardeningg aluminum alloy, containing magnesium and silicon as its major alloying elements. It has good mechanical properties and exhibits good weldability. It is one of the most common alloys of aluminum for general purpose use.
6063 is an aluminum alloy, with magnesium and silicon as the alloying elements. It has generally good mechanical properties and is heat treatable and weldable. 6063 is mostly used in extruded shapes for architecture, particularly window frames, door frames, and roofs. It is typically produced with very smooth surfaces fit for anodizing.
- T4: Solution heat treated and naturally aged to substantially stable condition
- T5: Cooled from an elevated temperature and then artificially age hardened
- T6: Solution heat treated and artificially age hardened
