    known

    ascastirons

    .

    Class

    80

    50

    means

    tensile

    strength

    is

    80

    ksi

    and

    yield

    is

    50

    ksi. Castingprocessesinclude:sandcasting,investmentcasting,resinshell,etc.. (diecastingdifficult

    duetotemp).

    Advantagesinclude:

    Lowliquidustemperature Readilycasttoformusefulshapes Inexpensive Dampingproperties(goodforvibrations)

    Disadvantages(vs.

    machined):

    Tolerances(+/ 0.06typicalforascastdimensions) Surfacefinish(2501000intypicalforsandcast) Sizelimitations Shrinkage/draft Fatigue Brittle! (Elongationcanbequitelow,especiallyforGrayIron)
