Antifriction carbon-graphites of Khimanit brand

The LEG Ltd. produces antifriction material of Khimanit brand, which is analogical to the soviet one and which is often used as mechanical compressor for friction joints of pumps, operating in acidic and alkali aggressive media. As all the rest of produced materials, this one has as advantage high strength characteristics, which result in longer durability, compared to the soviet analogs.

For confirmation refer the table below.

Our enterprise produces workpieces and end products made of them, which are approved with quality certificates.
