Fuel Injector Braze
This micrograph displays a brazed joint in a stainless steel fuel injector. The red central seam is the copper braze, while the yellow-toned regions on either side represent two different stainless steels. One steel is particle-free, while the other contains numerous microscopic inclusions. The orange loops around grain boundaries show where the copper has partially melted and diffused into the steel, creating a strong, sealed bond essential for fuel system performance.
