The Aluminum Bend Allowance Chart is an indispensable tool in the metal fabrication industry, providing precise guidance for calculating bend allowances in aluminum materials. By
Impact of Sheet Thickness on Bend Radius and Other Parameters. The thickness of the sheet metal directly impacts the bend radius and other critical bending parameters, such as V
Consider a 90° bend in a sheet of aluminum with a thickness of 2 mm and an inside bend radius of 5 mm. Using the material-specific formula for semi-hard copper, brass,
After determining the radius for bending aluminum plates, mark the angle onto the vertical edge of the tabletop. Then use cutting tools such as a miter saw or circular saw to
Thickness and Bend Radius. The thickness of the aluminum sheet and the bend radius are critical factors in material selection. Thinner sheets can handle tighter bend radii,
The K-factor in sheet metal bending represents the ratio between the thickness of the metal and an invisible line called the “neutral axis.” When a flat piece of material is bent the inside face of
If you’re bending 0.125-in.-thick aluminum 6061-T6, you could try for an inside radius that’s between 1½ and three times the material thickness. For 0.25-in.-thick T6 material,
Factor 2 – Thickness And Bend Radius. Another factor to consider is that during the process of bending, the metal hardens and strengthens by reason of the working effect. Apart from alloy
Sheet Metal Bending Calculation. Bend Allowance (BA) BA = [(0. × Inside radius) + (0.0078 × Material thickness)] × Bend angle, which is always complementary. The
For example, a flat sheet of aluminum is less stiff than that same sheet of aluminum bent into a V cross section. We recommend a minimum bend radius of 1t for all
What is the minimum bend radius for an aluminum part? The bend radius large enough to avoid cracking is a function of the alloy, temper, thickness, bend 3-1 provides
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by Protocase. We go beyond the general rules of sheet metal bending, as our
6.0mm copper sheet bending allowance: 10.3; 8.0mm copper sheet bending allowance: 12.5; 10.0mm copper sheet bending allowance: 15; 12.0mm copper sheet bending allowance: 17; 3.0mm stainless steel with V25 allowance: 6; 3.0mm stainless steel with V20 allowance: 5.5; For copper plates thicker than 6.0, the allowance for the lower die is
Feed a large sheet into the clamp bar of a bending brake, then lift the handles to bend the sheet to your desired angle. Lay your smaller aluminum piece on a block of wood cut to the desired bend radius. Tape a steel pipe to the top of

These values are recommended but are not guaranteed; the minimum
Aluminum: Softer than steel, aluminum can achieve tighter bends, with a recommended minimum radius of 1× thickness for thin sheets and 2–3× thickness for thicker sheets. What Is the Minimum Bend Radius of Sheet Metal in Press Brake Operations? If the bend radius is smaller, the stress on the outside of the bend will be greater and the
The Bend Radius Calculator will compute the minimum bend radius based on the input parameters and material properties. For a 2.0 mm thick aluminum sheet with a 90-degree bend, the calculator might output a minimum bend radius of 1.5T, which translates to 3.0 mm. Step 5: Verify Results. Refer to the table of typical bend radius data for
Sheet Metal Bend Radius Guidelines Here are a few key concepts to know about designing for sheet metal. Brackets, covers, cabinets, chassis, electrical enclosures. roughly 3-1/2 in. (88.9mm) square by 0.083 in. (2.1082mm) thick—about the same as a piece of 12-gauge brass or aluminum. Now, bend it evenly over the edge of the countertop. If
Impact of Sheet Thickness on Bend Radius and Other Parameters. The thickness of the sheet metal directly impacts the bend radius and other critical bending parameters, such as V-opening, bending force, and flange length. applies to structural steels with an approximate yield strength of 400 MPa. For aluminum, multiply the force values by 0.
What is the minimum bend radius for an aluminum part? The bend radius large enough to avoid cracking is a function of the alloy, temper, thickness, bend 3-1 provides recommended minimum bend radii for various alloy-tempers and thicknesses of sheet and plate for 90 degree bends; Table 3-2 provides recommended inside radii for 180 degree cold
Material Thickness and Inside Bend Radius. Just like all sheet metal, aluminum work-hardens during the forming process; that is, it gets stronger and harder by working (bending) it. When you are forming aluminum, if the radius is sharp (small) in relation to the material thickness, you will overwork the material, making it harder, more brittle
Common K-factors: For bending aluminum (0.33–0.4), for bending stainless steel (0.35–0.4). CAD software uses K-factor values to estimate bend allowances. This risk is minimized when a precise, sheet metal bend radius calculator is used to
