    Body material characteristics
    body material Material characteristics
    Gray cast iron (FC200) Is a kind of material used for thousands of years, for the low and normal temperature. Also used for daily use from cooking utensils to statues, shrines and other crafts.
    Nodular graphite cast iron (FCD450-10) Since its invention, it has been over half a century, but because of the unique characteristics of cast iron and
    at the same time with the toughness of copper, so the annual production volume is increasing, there will be further development in the future. Because it is a kind of ductile material, it is also called high strength casting.
    Nodular graphite cast iron (FCD-S)
    Stainless steel cast steel
    (SCS13A,SCS14A)
    Corrosion resistance, heat resistance, low temperature resistance and mechanical properties, but compared with other materials, the price is higher.
    Carbon cast steel for high temperature and high pressure (SCPH2) Because of toughness, hardness, tensile strength, impact value, therefore, for a variety of complete sets of equipment, high temperature, high pressure use.
    bronze (CAC401,CAC406) Bronze is one of the earliest castings used in human history, which is made of tin, zinc and lead in copper. Brass is an alloy of copper and zinc. Machining, corrosion resistance, used as a low pressure grade, small caliber valve material.
