![]() ![]() What is the right bend radius for sheet metal?īelow is Xometry’s minimum bend radius reference table which is based on theoretical sheet metal gauge thicknesses. SWAGELOK MS-BTB-M MANUAL Bench Top Tube Stainless Steel Bender - 2968. For example, if the thickness of the sheet is 2mm, the minimum bend radius should be 1t which is 2mm. Swagelok MS-HTB-6T Tube Bender, 3/8 in Tube OD, 15/16 in Bend Radius, Blue 423. lr 5D Stainless Steel 5D elbow If the radius is equal to the pipes diameter. The bend’s outer edge would crack if it exceeds the minimum bend radius which is typically specified according to the metal sheet thickness (t) like 1t, 2t, 3t etc.Ī typical recommendation is 1t for all sheet metal parts, which means the smallest bend radius should be at least equal to the sheet thickness. The bend radii listed are standard minimum if manufacturing for aircraft and. ![]() Moreover, bending imparts much strength to the sheet metal compared to their flatter counterparts.įor example, an aluminium sheet bent into a V cross section will be much stiffer and stronger than the same flat sheet.īending a metal sheet usually comes with a set of calculations and design requirements. In sheet metal fabrication, curving sheets according to a specific bend radius is one of the most common operations used to create flanges, curls, seams etc. (77.1 kg) without accessories Minimum tube wall thickness ( of O.D.) 4 with mandrel, 7 without mandrel The HB632 is capable of bending 1/2' O.D.
