Laser Cut and Bent Aluminum Sheet Metal Brackets
These are custom sheet metal brackets, angles, clips and supports made by fiber laser cutting and CNC press-brake bending in aluminum (5052, 6061) or stainless steel. Parts can be anodized, polished or sandblasted, and critical holes held to tighter tolerance by secondary machining. They are for product and equipment designers who need affordable brackets without stamping dies.

Manufacturing
How we make this part
Process, material options and inspection for laser cut and bent aluminum sheet metal brackets.
Flat patterns are generated from your 3D model with bend allowances for the specific sheet and tooling, then cut by fiber laser. Bending on CNC press brakes with back-gauges repeats angles and flange lengths accurately across a batch. Holes that must align across bends can be laser cut after bending or finished by drilling, which avoids stack-up from bend tolerance. Edges are deburred before finishing.
5052 aluminum is the preferred bending grade because it forms tight radii without cracking; 6061-T6 is stronger but needs larger bend radii. Stainless 304 is used for corrosion resistance and strength, typically finished by brushing, polishing or passivation. Anodizing suits aluminum brackets; sandblasting before anodize gives an even matte look. Minimum flange length and bend radius are reviewed against sheet thickness.
First articles are checked for bend angles with protractors and gauges, flange lengths and hole positions against the drawing. Critical dimensions are 100% inspected before shipment. Typical uses include PCB mounting brackets, sensor and camera brackets, DIN-rail supports, cable trays and furniture brackets, ordered either as loose parts or kitted with hardware for assembly.
FAQ
Frequently asked questions
Which aluminum grade is best for bent brackets?
5052-H32 is the usual choice: it bends to tight radii without cracking and resists corrosion well. 6061-T6 is stronger but can crack on tight bends, so it needs a larger inside radius. If strength is critical and bends are tight, consider stainless steel or a thicker 5052 sheet.
How accurate are laser cut and bent parts?
Laser-cut profiles are typically within about ±0.1 mm, and bent flanges usually ±0.2 mm depending on material and thickness. Where holes must align more precisely across bends, we add secondary drilling or machining after forming to hit tighter positions.
