Laser-Cut Aluminum — Built for Projects That Need to Stay Light

The Aluminum Cutting Challenge

Aluminum fights back when you cut it. The same properties that make it valuable — high thermal conductivity and reflectivity — also make it one of the trickier metals to process cleanly on a laser. Without the right wavelength, power density, and assist gas strategy, you get ragged edges, excessive dross, and heat distortion that throws your part out of tolerance.

At Laserbend, we run fiber laser systems tuned specifically for non-ferrous metals. High-purity nitrogen assist, optimized beam focus, and controlled feed rates let us cut 5052, 6061, and 7075 with edges that are clean enough to skip secondary cleanup on many jobs. We cut it. You assemble it. No surprises in between.

Grades We Stock and Cut

5052-H32
This is the workhorse for formed parts and welded assemblies. High magnesium content gives it excellent saltwater resistance and solid fatigue strength, but it stays soft enough to bend and shape after cutting. We see it constantly in marine hardware, fuel tanks, electronic chassis, and architectural panels. If your part needs to take a bend or a bead without cracking, 5052 is usually the right call.

6061-T6
When you need more structural rigidity, 6061-T6 delivers. The heat-treated temper gives it nearly double the yield strength of 5052, and it machines beautifully if your part needs threaded holes or milled pockets after cutting. We cut a lot of 6061 for robotics frames, drone components, bicycle parts, and any assembly where parts need to stay square under load. It welds well with the right filler wire, though you’ll want to account for the heat-affected zone in your design.

7075-T6
This is the strongest commercially available aluminum alloy, period. It’s the material you spec when failure isn’t an option — aircraft fittings, high-stress brackets, and competitive racing components. The tradeoff is reduced corrosion resistance and more demanding weld requirements, but for pure strength-to-weight ratio, nothing else in the aluminum family comes close. We keep 7075 in stock for jobs where performance outweighs cost.

What Our Tables Look Like in Practice

Rather than burying you in data, here is what you actually need to know when you send us a file:

• Sheet Capacity: We process full 4×8-foot and 5×10-foot sheets, so your nested parts can be as large as the bed or as small as a quarter-inch square.
• Thickness Range: From thin 0.032-inch gauge up to 0.375-inch plate, depending on alloy. 7075 is typically held to 0.125-inch and 0.250-inch stock.
• Feature Size: We hold minimum internal features down to 0.02 inches on thin gauges, scaling up proportionally as material gets thicker.
• Tolerances: Expect ±0.004 inches on material under 0.080 inches, moving to ±0.030 inches on heavy 0.375-inch plate. Every thickness has its own sweet spot.
• Bending: All three grades can be formed on our press brakes after cutting, with 5052 being the most forgiving and 7075 requiring the most care.

If your drawing calls for something outside these ranges — metric stock, oversized plate, or a specialty alloy like 2024 or 5083 — we source it and cut it. Just send the spec.

Where Laser-Cut Aluminum Parts End Up

• Marine & Coastal: 5052 brackets, panels, and tanks that survive constant salt spray without heavy protective coatings.
• Robotics & Automation: 6061 frame rails, motor mounts, and gantry plates where every ounce of weight matters but rigidity can’t be sacrificed.
• Aerospace & UAVs: 7075 structural fittings and 6061 avionics housings cut to tight aerospace tolerances.
• Consumer & Architectural: Decorative panels, LED mounting plates, and retail fixtures where the natural aluminum finish is part of the design.
• Automotive & EV: Battery enclosures, heat sinks, and mounting trays that need to dissipate heat and resist corrosion.
