3.2.4 Interfacing Structural Components

The components that attach to a forging may present either design problems or opportunities for product improvement. Interfacing components made from different materials may be subject to galvanic corrosion, as noted above. Interfacing components that have significantly different coefficients of thermal expansion, such as aluminum and steel, and are subject to temperature excursions, may require consideration in the attachment methods to tolerate differentials in expansion.

The high ductility usually achieved in forging often permits the design to include features that can be staked, crimped or swaged to reduce or eliminate fasteners. It may also be possible to redesign, reducing parts count and eliminating both fasteners and subassembly operations. This opportunity should be explored when products made by other processes are redesigned as forgings.
