We have a situation where we need to take some weight out of a component. We want to switch the material to 2024 AL, but the component threads into another component made of 303 SS. The 303 SS component sees a crimp operation, so we are hesitant to change both to 2024 AL since we have dealt with aluminum cracking during the crimp process in the past. We will have the aluminum component anodized, but do we still have to worry about galvanic corrosion? The assembly will be used in fuel, so exposure to water moisture will be minimal.
