    Rockwell Hardness: F40

    Material: C110

    Condition: H02 = Half Hard

    Tensile: 42,100

    Yield: 36,300

    Rockwell Hardness: B40

    Material: C110

    Condition: H04= Full Hard

    Tensile: 50,000

    Yield: 45,000

    Rockwell Hardness: B50

    The industrial sector uses copper where there is a need for ductility (plumbing or roofing) or electrical conductivity (electromagnets, electrical motors, or wave guides).  Copper washers are also used as crush washers to provide seals, primarily in the automotive industry.
