Copper washers Manufacturers | Metco Overseas

Similar to the conventionally used plain or flat washer, the surface of the Copper Fender Washer is flat, with the only exception being the outer diameter, which is larger as compared to a regular flat washer.

For starters, it is a ductile metal that is well known for its soft and malleable properties. This allows copper to be formed into any shape, so you can easily get a copper washer in any design needed. It is also used as a conductor of heat and electricity.

Types of Copper Washers

Copper Crush Washer

Copper crush washers really shouldn't be re-used. To seal effectively the copper must be soft, as it is in an annealed state. There is a decent chance a used, crushed, aged copper washer might seal again, but the only way to be sure is to try.

Copper Flat Washer

For starters, it is a ductile metal that is well known for its soft and malleable properties. This allows copper to be formed into any shape, so you can easily get a copper washer in any design needed. It is also used as a conductor of heat and electricity.
