Expanded Aluminum Industry Information

Expanded Aluminum

Expanded aluminum is a rigid and non-raveling metal framework of interlinked bars created by a machining process in which a sheet or coil is simultaneously slit and drawn. The framework of expanded metals is actually a solid piece of construction that exhibits an open grid-like pattern.

While a number of other metals are common in expansion, the properties and characteristics of aluminum make it ideal for industrial, commercial, and residential use.

Applications of Expanded Aluminum

Aluminum is a silvery-white non-ferrous metal that is both durable and aesthetically pleasing. With lighter weight and better corrosion resistance than expanded steel, aluminum is used in construction, automotive, water and air filtration, cooking, packaging, aquarium, aerospace, power generation, marine, medical, and electronics industries.

Unlike many metals that become brittle in cold temperatures, aluminum actually strengthens at low temperatures, making expanded aluminum enclosures essential for refrigeration applications as well. Pure aluminum, however, is very ductile and malleable, which limits its use. To improve strength to weight ratio, expanded aluminum is often alloyed. Alloyed aluminum is used for support, security, and protection in the form of grilles, guards, floors, and walkways.

Manufacturing Process of Expanded Aluminum

Metal expansion is a fairly simple, but effective process that has changed little throughout the years. Sheets or plates of aluminum are fed into an automated expansion machine. In the machine, several dies are used to slit the metal hundreds or even thousands of times depending on the size and desired outcome. This creates an offset alternating pattern of small cuts. While the dies are in motion, the metal is simultaneously drawn through a press or roller. The combination of heat and pressure stretches the metal and causes the diamond, round or irregularly shaped holes to swell. The solid aluminum is transformed into a mesh-like screen.

Despite the gaps, the sheet is still a solid piece of construction and therefore has no seams, welds or joints that might work loose over time in other metallurgical processes. The use of a single sheet is important as the interconnected network of strands and bonds distribute weight evenly so no one portion is overloaded. The size and density of the apertures or percentage of open space plays a significant role in the weight capacity of expanded aluminum and should be taken into account with regards to intended use. Gauge, length, width, and height of the metal frame should also be considered.

Benefits of Using Expanded Aluminum

Because metal expansion results in a pattern of uniform openings, air, sound, liquid, and light can pass through these barriers for improved ventilation, visibility, and acoustics. Compared to punched or perforated metal, expanded aluminum is cost effective, as it slits the metal, leaving no waste. As the third most abundant element in the Earth's crust, the cost of aluminum is already much lower than many competing metals, such as titanium.
