1.灰铸铁具有较好的减震性，用灰铸铁制作机电设备上的底座或机架等零件，比如测功器铸铁平台。能够有效的吸收机器振动的能量，从而起到阻尼的作用，这也是灰铸铁最为重要的性能。
2.灰铸铁具有良好的导热性能，用灰铸铁制作内燃机上的汽缸体，汽缸盖时，可迅速到处大量的热量，这中良好的导热性低于在高温下工作的机电设备是很重要的。
3.灰铸铁具有良好的润滑性能，用灰铸铁制作机电设备上经受滑动摩擦的零件时，具有良好的减磨性能。在有水分存在的情况下，石墨是很好的润滑剂，而一旦石墨从基体上脱落时所留下的空间又便于存住润滑油，这也是灰铸铁作为良好耐磨材料的重要条件之一。
4.灰铸铁在同一应力下反复加载时，具有加载次数增加，应变曲线弯曲程度明显减小，卸载后残留塑性变形也减少的特性。铸铁平台就是利用这种特性，可通过过精加工前一定次数的预加载，获得高的铸件稳定性。
5.灰铸铁具有良好的铸造和切削加工性，其熔炼比较方便，与铸钢相比，融化温度较低，熔炼设备和熔炼工艺都都比较简单，在铸造性能方面，灰铸铁液的流动性良好，铸件不易开裂。
5 basis for cast iron plate casting with
gray iron
1. Gray cast iron has good shock
absorption, and uses gray cast iron to make parts such as base or frame on
electromechanical equipment, such as dynamometer cast iron platform. It can
effectively absorb the energy of the vibration of the machine and thus play the
role of damping, which is also the most important performance of gray cast
iron.
2. Gray cast iron has good thermal
conductivity. The cylinder block on the internal combustion engine is made of
gray cast iron. When the cylinder head is used, a large amount of heat can be
quickly everywhere. It is very important that the good thermal conductivity is
lower than that of the electromechanical equipment working at high temperature.
.
3. Gray cast iron has good lubricity. When
using gray cast iron to make parts subjected to sliding friction on
electromechanical equipment, it has good anti-wear performance. In the presence
of moisture, graphite is a good lubricant, and once the graphite is detached
from the substrate, the space left is convenient for storing the lubricating
oil, which is one of the important conditions for gray cast iron as a good
wear-resistant material. .
4. When the gray cast iron is repeatedly
loaded under the same stress, the loading times are increased, the strain curve
is obviously reduced, and the residual plastic deformation is also reduced
after unloading. The cast iron platform utilizes this feature to achieve high
casting stability by preloading a certain number of times before finishing.
5. Gray cast iron has good casting and
cutting processability, and its smelting is convenient. Compared with cast
steel, the melting temperature is lower, the smelting equipment and the
smelting process are relatively simple, and the flowability of gray cast iron
liquid in terms of casting performance Good, the casting is not easy to crack.
