Butterfly Valve
This micrograph displays the copper alloy used in the butterfly valve of the air intake manifold. The image reveals large, well-defined grains with a distinctive feature called “twinning”—seen as parallel lines running within the grains. Twinning is a result of deformation during metal processing and contributes to the material’s mechanical properties. This structure enhances the valve’s ability to withstand thermal cycling and repeated actuation within the engine system.
