Their properties are better than those of metal-impregnatedgraphite sealing materials and their lifetime is increased by 4-6 times compared with the latter.
与金属浸渍石墨密封材料相比，其性能更为优良，使用寿命提高4—6倍。

The results indicate that, the fracture toughness of copper impregnatedgraphite is not much greater than that of graphite at room temperature, because the liquid copper does not wet the graphite.
The relationship between the thermal physical and mechanics properties with the silver impregnated carbon graphite clack seat and bushing materials and thermal shock divisor was discussed.
