An integrated energy absorbing system of a vehicle with a front integrated energy absorbing casting and a back integrated energy absorbing casting. Each front and back casting is a single unified casting that makes up the integrated energy absorbing system. Ribbed sections such as 'I' sections and “C” sections make up the castings and are formed from a variety of different techniques and/or formings such as cutout, waveform profile, tapering, flaring and/or rib spacing. Additional sections such as closed section castings may also be integrated in the integrated energy absorbing system.

Integrated energy absorbing castings

In various embodiments, aluminum alloys having yield strengths greater than 120 MPa, and typically in the range from 140 MPa to 175 MPa, are described. Further, such alloys can have electrical conductivity of greater than 45% IACS, typically in the range from 45-55% IACS. In one embodiment, the aluminum alloy comprises Si from 1 to 4.5 wt %, Mg from 0.3 to 0.5 wt %, TiBfrom 0.02 to 0.07 wt %, Fe less than 0.1 wt %, Zn less than 0.01 wt %, Cu less than 0.01 wt %, Mn less than 0.01 wt %, the remaining wt % being Al and incidental impurities. Such alloys can be used to cast a variety of automotive parts, including rotors, stators, busbars, inverters, and other parts.

Casting aluminum alloys for high-performance applications

A component is formed by welding a plurality of sheets of metal to form a blank with a number of weld nuggets, placing the blank between a die section and a lid section, heating the die section to heat the blank, and introducing a pressurized gas between the lid section and the die section to press the blank into a mold in the die section to form a component. The number of weld nuggets has a desired thickness ratio between about 1.1 to about 1.25 such that the plurality of sheets of metal and the component formed have a number of characteristics that are substantially the same.
