Material and Stock Forms for Hydroforming

Hydroforming parts are made from either sheet stock or coil stock, depending on the blanking process used (see General Process for Hydroforming).

For Router Cut and Laser Cut, standard sheet stock dimensions (specified by cost model variables) are used, provided such stock is big enough for the blank, taking into account trim strips and any blank addendum. See Material Stock Selection for Laser Cut and Router Cut Routings.

For Offline Blanking (shear-press based blanking), coil stock width is based on the extent of the strip-nested flat pattern (with addendum, if any) in the direction perpendicular to the coil flow, supplemented by edge margins, as well as (for 2-out parts) part spacing width. See Coil Width for more information.

Note to VPE Administrators: Actual coil stocks are not supported. Do not add actual stock to a Sheet Metal--Hydroforming VPE.

Materials include the following types:

• Aluminum

• Copper

• Galvanized Steel

• Stainless Steel

• Steel

• Titanium

Material composition details include the following:

• Unit Cost

• Density (kg/m3)

• Tensile Yield Strength (MPa)

Part flattening (to determine blank shape) sometimes takes into account additional material properties, including the following:

• Young's Modulus

• Poisson's Ratio, K (strain-hardening coefficient)

• N (strain-hardening exponent)

• R (Lankford parameter, average)

See Flattening for Hydroforming for more information.

Material details include equivalent DIN and EN name standards for use with regional VPEs.

Note: If you change the selected material for a part, the part’s CAD file must be accessible to aPriori so that it can recalculate the flattened part outline.
