Aluminum channel is widely used in manufacturing, commercial and residential applications where strength and resistance to corrosion are important. Additionally, it can be machined and welded, adding to its versatility and popularity in many industries.
Two aluminum alloys, 6063 and 6061, lend themselves specifically to aluminum channel extrusion. Aluminum channel fabricated with sharp, right-angled corners inside and outside is typically made with the 6063 alloy, and these channels—also known as Aluminum Association channels—are often the choice for architectural applications. Aluminum Association Standard channels, on the other hand, are often supplied in 6061 alloy, do not have distinct right angles, and are preferred for structural use.
Aluminum Alloy 6061 versus Aluminum Alloy 6063
6061 aluminum is the most commonly used aluminum alloy. The properties of 6061 that distinguish it from 6063 are its superior strength, heat treatability and ability to undergo machining and welding with greater ease than its 6063 counterpart. 6061 may be anodized, which results in an additional layer of protection for finished components.
6063, also called architectural aluminum, has a smooth surface finish already, thereby minimizing production finishing. 6063 is slightly more corrosion resistant than 6061 and is often preferred where strength is not the over-riding specification and where cosmetic appearance is critical.
There are a number of profiles which can be made from the different alloys of aluminum C channels, hat channels, U channels, slide track channels nut channels and slide track channels—to name few. The aluminum Z channel is also commonly used in various applications.
Uses of Aluminum Z Channel
Also known as Z-bar, Zee and Purlin, aluminum Z channel is widely represented in many manufacturing efforts:
* Architectural trim
* Displays
* Cabinets
* Storage bins
* Enclosures
* Garage doors
* Support
* Metal furniture
* Reinforcements
* Fencing
* Metal buildings
* Stiffeners for PVC window and door frames
* Slides and tracks
* Framing
* Store fixtures
Besides the 6061 and 6063 alloys, which are usually “stock,” aluminum Z channel may also be manufactured from another alloy whose properties may be a better fit for a particular project. Because there are many factors to consider when deciding on the alloy to use, it is best to consult an industry expert to ensure that the alloy from which the Z channel is made will support the project’s engineering requirements and desired aesthetics.
