  • Publication number: 20230373563
    Abstract: 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 ā€œIā€ sections and ā€œCā€ 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.

  • Publication number: 20220349034
    Abstract: 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 %, TiB2 from 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.
