铸石的主要性能是：硬度高（莫氏硬度为7～8）；耐磨性好（耐磨系数为0.09～0.14克/厘米，抗腐蚀性能强，除氢氟酸和热磷酸外，能抗任何酸碱的腐蚀（耐酸性大于96％，耐碱性大于98％）。 铸石具有很好的耐腐蚀、耐磨性能，其耐酸碱性可达99％以上，耐磨性比锰钢高5～10倍，比碳素钢高数十倍；其莫氏硬度7～8，仅次于金刚石和刚玉。但其韧性、抗冲击性较差，切削加工困难。
The main properties of the cast stone are: high hardness (Mohr's hardness is 7-8); good wear resistance (wear resistance coefficient is 0.09-0.14g/cm, strong corrosion resistance, and can resist any acid-base corrosion except hydrofluoric acid and thermal phosphoric acid (acid resistance is greater than 96%, alkali resistance is greater than 98%). The caststone has good corrosion resistance and wear resistance. Its acid-base resistance is over 99%. Its wear resistance is 5-10 times higher than manganese steel and 10 times higher than carbon steel. Its Mohs hardness is 7-8, second only to diamond and corundum. But its toughness and impact resistance are poor, and it is difficult to cut.
