Aluminum vs Copper Crush Washers: 6 Differences Revealed!
In terms of strength, the copper is a clever winner here. The tensile strength of copper is 380 MPa or 55,114 psi. On the other hand, the tensile strength of aluminum is up to 200 MPa, or 29,000 psi. That means copper can hold up to 55,000 pounds per square inch of pressure, whereas aluminum can hold up to 29,000 pounds per square …

How do they measure cup pressure
Posts: 1,558. C.U.P is measured with a copper crusher. Basically it is a hole precisely drilled into the chamber of the test gun. The hole is there to accept a copper pellet that is measured before and after the cartridge is fired. The amount of difference in length of the copper pellet is used to calculate the pressure.
CHAMBER PRESSURE
That pressure created in the chamber of a firearm by the expanding propellant combustion gases. Normally measured by means of a piezoelectric pressure transducer or a copper crusher.
