Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
Minimum bend radius sheet metal steel.
It requires an inside bend radius of at least 6x the material thickness.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
Maximum dimensions are 2980 x 1200 mm.
Discover all our calculation tools in the calculators section of the top menu.
Recommended minimum bend radii for steel and aluminum.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
To keep it simple i also use a 2 mm inside radius.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Table 1 preferred recommended 90 degree bend radii for various sheet metals.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
The minimum inside bend radius is even larger when bending with the grain.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
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.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
3003 h14 is extremely ductile.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
Use this document to choose values that are both manufacturable and meet your needs.
Let s say i have a 2 mm thick sheet and i want to bend it.
This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
These dimensions are all in relation to a 90 angle.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Maximum weight is 40 kg.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The problem with bending too tightly.
5052 h32 aluminum bends in about the same way as mild steel.
Bend radii minimum bend sizes.
In steel between 0 5 and 0 8 in.
Maximum sheet thickness for all other steel is 6 mm.
If a piece of material is bent too tightly problems can occur.
For example 6061 t6 aluminum is very difficult to bend.
Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form.
