Editing Connecting rod (section)

=== Materials ===
The materials used for connecting rods widely vary, including carbon steel, iron base sintered metal, micro-alloyed steel, spheroidized graphite cast iron.<ref name="Yamagata 2005 p. 7">{{harvnb|Yamagata|2005|p=7}}</ref> In mass-produced automotive engines, the connecting rods are most usually made of [[steel]]. In high performance applications, "billet" connecting rods can be used, which are machined out of a solid [[Billet (manufacturing)|billet]] of metal, rather than being [[casting|cast]] or forged.

Other materials include  T6-[[2024 aluminium alloy]] or T651-[[7075 aluminium alloy]], which are used for lightness and the ability to absorb high impact at the expense of durability. [[Titanium]] is a more expensive option which reduces the weight. [[Cast iron]] can be used for cheaper, lower performance applications such as motor scooters.
