Materials science
Why AlMg3? Light, durable, easy to work with
For aluminium laser-cut parts, Laserteile Online relies on the proven magnesium alloy AlMg3 – the standard for construction and outdoor use.
Lightweight
≈ 1/3Aluminium weighs only around a third as much as steel. That saves weight on façades, vehicles and anywhere every kilogram counts – with the part's full function retained.
Corrosion-resistant
AlMg3The magnesium alloy AlMg3 is considered seawater-resistant and forms a protective oxide layer on its own – ideal for outdoor applications, with no paint at all.
Easy to weld
MIG/TIGAlMg3 welds and joins well. That means you can process your laser-cut parts into assemblies, frames and enclosures without any trouble.
Easy to bend
≤ 12 mmAlMg3 is easy to cold-form. Laserteile Online bends your aluminium cut parts right along with the order – up to 12 mm thick and 3 m of bend length on the press brake.
For comparison: steel offers more strength per euro and can be laser cut up to 20 mm – if weight is secondary, it's worth a look at steel laser cutting. Aluminium scores wherever low weight, corrosion resistance and a clean look come together. For garden and façade projects with a deliberate weathering patina, it's also worth a look at Corten steel laser cutting.
Production
The fibre laser cuts aluminium reliably – even when it's reflective
Aluminium reflects laser light strongly. A problem for older CO2 machines – everyday business for the modern fibre laser.
Laserteile Online cuts AlMg3 on a Bystronic ByStar Fiber. Compared with conventional CO2 lasers, fibre laser technology works significantly faster and more energy-efficiently in laser cutting – with high precision and a clean cut edge, especially with reflective materials like aluminium.
- Reliable cutting in reflective aluminium – fibre laser instead of CO2
- Faster and more energy-efficient than conventional CO2 lasers
- Precise contours, even with delicate cut-outs and hole patterns
- Low-maintenance, robust machine technology for consistent quality
Thicknesses + prices
Aluminium sheet laser cutting: all thicknesses directly in the calculator
As a standard material, AlMg3 is almost always in stock in every thickness – you simply choose the thickness and quantity, the rest is an instant price.

As a guide: the material cost basis for AlMg3 is €6.20/kg (as of August 2026) – that's the raw material basis, not the part price. The instant price calculator works out the actual price of your cut part from contour, cut length and quantity. Which factors determine the price is explained in the guide What does laser cutting cost?
More than the cut
Bending up to 12 mm, grinding + more options
Aluminium cut parts rarely need to stay flat. Order every follow-up step directly with your job – from a single supplier.
- Sheet metal bending – aluminium up to 12 mm, bend length up to 3 m, 150 t press force with live angle monitoring
- Grinding – evenly ground visible surfaces, selectable as an option for AlMg3 in the calculator
- Deburring + tumbling – clean, burr-free edges for assembly and handling
- Threading + powder coating – ready-to-install parts instead of rework in your own workshop
Applications
What aluminium laser-cut parts are used for
From a single spare part to a small batch – these industries order AlMg3 cut parts from Laserteile Online.
Lightweight construction + transport
Where weight costs money, aluminium is the first choice – from the transport industry to mobile construction.
Façades + architecture
Cladding, panels and decorative elements: easy to install, weather-resistant with no extra paint required.
Electrical + enclosure construction
Front panels, mounting plates and enclosure parts – laser cut, bent on request and fitted with threads.
Vehicle construction
Brackets, covers and add-on parts where low weight and corrosion resistance come together.
Signs + signage
Logos, lettering and displays: aluminium stays attractive outdoors and can be finely contoured.

FAQ
Frequently asked questions about aluminium laser cutting
Which aluminium does Laserteile Online laser cut?
The instant price calculator offers the alloy AlMg3 – a seawater-resistant aluminium-magnesium sheet that welds and bends well. AlMg3 is the standard alloy for laser-cut parts in outdoor and structural applications. For other aluminium materials, simply send an individual enquiry.
Up to what thickness can aluminium be laser cut?
AlMg3 can be ordered directly in the calculator in 12 thicknesses from 0.5 to 12 mm. The maximum sheet format is 3,000 × 1,500 mm. Standard materials such as aluminium are almost always in stock in every thickness – that keeps delivery times short.
What does having aluminium laser cut cost?
The instant price calculator works out the exact price in about 60 seconds from your CAD file – depending on thickness, cut length and quantity. As a guide: the material cost basis for AlMg3 is €6.20/kg (as of August 2026). The minimum order value is €50 net plus shipping.
Can aluminium even be cut with a laser?
Yes, very well – with the right machine. Aluminium reflects laser light strongly, which was a problem for older CO2 lasers. Modern fibre lasers such as Laserteile Online's Bystronic ByStar Fiber, however, cut aluminium reliably, quickly and with a clean cut edge.
Can I also have my aluminium cut parts bent?
Yes. Laserteile Online bends aluminium up to 12 mm thick – on a press brake with up to 150 t of press force, 3 m of bend length, a 6-axis back gauge and live angle monitoring. You simply select bending as an add-on option to the laser cutting.
Can laser-cut aluminium be ground?
Yes, grinding is selectable as an add-on option for AlMg3 in the calculator. That gives visible parts such as front panels or cladding an evenly ground surface. Other options are deburring, threading, tumbling and powder coating.
How quickly are laser-cut aluminium parts delivered?
The standard delivery time starts at 2 working days. Because AlMg3 is almost always in stock in every thickness, production sometimes starts within 24 hours when material is available. For a surcharge, same-day express production is possible.
