Aluminium Channel: Overview and Production
What Is Aluminium Channel?
Aluminium channel is a distinctive type of aluminium extrusion widely used for structural applications. It is characterized by its “C” shape in cross-section, featuring two flanges that extend from one side of a web.
How Are Aluminium Channels Made?
Aluminium channels are manufactured through the extrusion process, where round aluminium stock is pressed through a channel-shaped die using a high-pressure ram. There are two primary extrusion methods:
- Direct Extrusion: The die is fixed in place while the ram pushes the billet through the hollow die.
- Indirect Extrusion: The billet remains static, and the die, housed within a hollow ram, is pushed along the length of the billet.
These methods can be further categorized into:
- Hot Extrusion: The aluminium stock is heated to a fully plasticized state and extruded in a vacuum to prevent oxidation.
- Cold Extrusion: The billets are shaped at or near room temperature.
- Warm Extrusion: The stock is heated to a temperature between 800º and 1800º F, depending on the alloy composition.
After extrusion, the aluminium channels are straightened on a stretcher, making them ready for shipment and use.
Aluminium Round Bar: Characteristics and Uses
What Is An Aluminium Round Bar?
Aluminium round bar is a long, cylindrical metal bar that finds numerous industrial and commercial applications. It is commonly used for making shafts and is available in various metals including hot-rolled steel, cold-rolled steel, aluminium, and stainless steel.
Aluminium round bars can be purchased online and customized to preferred specifications.
Applications of Aluminium Round Bars
Aluminium round bars are highly machinable, allowing for the quick alteration of complex parts with excellent results. Drilling and cutting can be done with basic DIY tools, and smaller diameters can be easily and precisely cut with a hacksaw.
This product is popular due to its lightweight, high strength-to-weight ratio, excellent corrosion resistance, and ease of machining. Common uses include:
- Precision turned parts
- Wheels and pulleys
- Fasteners
- Machine components
Aluminium Flat Bar: Features and Uses
What Is An Aluminium Flat Bar?
Aluminium flat bar, also known as a rectangle bar or strip, is named for its rectangular cross-section, measured by its width and depth.
Uses of Aluminium Flat Bars
Available in 6063 or 6082 grade aluminium, flat bars are lightweight with good strength-to-weight properties. They are ideal for:
- Manufacturing jigs
- Machine parts
- Shop fittings
- Frames
- Road transport
- General fabrications
These bars also offer excellent corrosion resistance.
Aluminium Angles: Equal and Unequal
Aluminium Equal and Unequal Angles
Aluminium equal angles and unequal angles are used to control, safeguard, strengthen, and support various surfaces. Smaller angles are perfect for minor projects like wall corners, counters, and worktop edges. These extrusions provide superior corrosion resistance and a high-quality surface finish.
Common Uses for Aluminium Angles
- Window frames
- Door designs
- Shop fittings
- Rails, posts, and balustrades
