are copper washers and crush washers the same?
Crush washers are cupped. They are made of copper and aluminum. I have even seen steel for different applications.
The crush washers are probably extruded as pipe or sheet and cut or stamped into washers whereas the others were probably stamped or cut from a copper cast. The crush washers can be bent back and forth a few times without breaking but a cast washer would break right off.
