Also known as crush washers, these are made of soft metal that deforms under pressure to fill gaps around the nut or screw. Often found in oil drain valves, they withstand stress and wear better than plastic and rubber washers, but aren't as leak-resistant. Metal sealing washers are not reusable.
Aluminum—These washers are an economical alternative to copper. They have similar corrosion resistance but require more effort to crush.

Bonded Sealing Washers
 |
These washers create a stronger seal than metal or rubber alone to lock air and fluid in, while keeping dust and contaminants out. The flexible rubber layer compresses to fill gaps, while the metal backing stops the washer from squeezing through the hole. These washers are a great solution if you have a hole larger than your fastener that you need to seal. Reuse them a handful of times, as long as the material isn't damaged.
Aluminum and Neoprene—These washers are as corrosion resistant as stainless steel but not as strong.
