Aluminum or steel material properties...

Aluminum or steel material properties...

Does anyone have material properties for either JAC270D steel or X621 aluminum? These are sheet stock metals for automotive body panels. Any help is appreciated.

RE: Aluminum or steel material properties...

JAC270D is a low carbon cold-rolled steel suitable for deep drawing. Ultimate tensile strength > 270 MPa, yield strength (depends on thickness, this is for 1 mm < t < 3.2 mm) 115-205 MPa. The composition is not explicitly defined, but it must be sufficiently resistant to aging (no stretcher strains for at least 3 months manufacturing). I am not familiar with the designation X621 for an aluminum alloy. Is this a casting or sheet metal?

RE: Aluminum or steel material properties...

Both the X621 aluminum and the JAC270D steel are in sheet form. I am dealing with 1 mm thick sheet metal for both the aluminum and the steel. We are trying to run some thermal load tests on them.
