Precision Cutting of Aluminium: A Guide to Getting the Perfect Finish
Aluminium is a remarkably versatile metal, offering an excellent balance of strength, corrosion resistance and lightweight properties. These characteristics make it ideal for use across industries such as construction, automotive, aerospace and fabrication. However, due to the varying hardness and composition of different aluminium alloys, the cutting process is rarely one-size-fits-all. At 1st Choice Metals, we understand how the unique properties of each grade can affect the outcome of the cut, and we tailor our approach to suit.
We primarily supply three aluminium grades: 6063T6, 6082T6 and 1050H14. 6082T6 is a medium strength alloy that machines well but requires precision when sawing, making it a popular choice for structural applications. 6063T6, often referred to as an architectural alloy, is known for its smooth surface finish and is ideal for intricate profiles. 1050H14 is a bendable grade of sheet aluminium, a service which we can provide should you need your aluminium sheets folded. In addition to the alloy type, the profile of the aluminium itself plays a key role. Angles, channels and box sections all require specialist tooling to ensure clean, consistent results. The thickness of the material will also influence both the choice of cutting method and the machinery used.
Choosing the Right Method for Cutting Aluminium
There are several ways to cut aluminium, each suited to different applications and finish requirements. At 1st Choice Metals, we offer a comprehensive range of cutting options designed to deliver accuracy, efficiency and outstanding results.
Sawing is the most common and cost-effective method, perfect for straight cuts on plate, bar and extrusion. With the right blades and lubrication, it produces clean edges with minimal burring, making it ideal for most fabrication tasks.
Machining is used where tighter tolerances or intricate shapes are needed. By using precision milling and turning, we can achieve custom cut aluminium profiles to exact specifications, particularly useful for complex engineering applications.
Shearing or guillotining offers a fast and efficient way to cut sheet aluminium to size, especially where high volume and uniformity are required. While this method can produce a sharper edge, it may require finishing to smooth out the burrs.
Laser cutting, though less commonly used for aluminium due to reflectivity, is a high-precision option that works well for thinner sheets and detailed work. When required, we can source laser-cut aluminium via our trusted partners.
Finishing Touches That Make the Difference
Cutting aluminium is only the first step. To ensure a professional appearance and safe handling, we offer several post-cutting finishing options.
Sanding and polishing help to prepare surfaces for further finishing or to meet the requirements of visible, decorative use. This can also help to remove small surface imperfections caused during the cutting process.
Surface treatments such as powder coating and anodising are available through our finishing partners, allowing you to enhance both the appearance and durability of your cut to size aluminium. These options are particularly useful for external applications or where colour and corrosion resistance are important.
