Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
Bending 2024 t3 aluminum sheet.
Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated.
Minimum sheet size available is 2 x 4.
2024t3 alclad aluminum sheet aluminum alloy sheet is sold in the thicknesses and sheet sizes shown in the table.
There will be four 90 bends.
With 2024 t3 040 sheets is there plastic on both sides for protection as you noted is the case for 2024 t3 025 sheets.
Annealed sheet can be bent to a radius approximately equal to its thickness.
From non heat treatable 3003 and 5052 to the heat treatable 2024 6061 and 7075 you have many options from which to choose.
As this happens you gain a small amount of total length in your part.
But the question remains the same which alloy is the best product for bending.
Just asking advice on which alloy will bend well crack the least and when bent stay that way with minimal springback.
I work at an aerospace company and i need to bend aluminum parts 6061 t6 and 2024 t3 alloys of different thickness in three groups.
I have formed 032 2024 t3 sheet in a similar brake with the correct nose radius inserts and spent a lot of time dialing in the brake to get an acceptably straight bend line.
The following alloys are all available in my chosen thickness of sheet stock.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The minimum bend radius is affected by the kind of material thickness of the material and temper condition of the material.
Clinton aluminum offers a variety of products each covering a wide range of applications and processes.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
For this example an l channel made from 2024 t3 aluminum alloy that is 0 032 inch thick will be bent.
There was a lot of deflection in the brake itself at this thickness definitely pushing its capacity at only 032.
2024 t3 5052 h32 6061 t6 my parts will be stamped to roughly 1 2 x 3 4 and then formed in a series of stations.
When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.
