Graphite Sheet with Metal Foil

 The leaf is made from thermo- advanced graphite with an insert from a metal foil (stainless steel, nickel) thickness 0,05mm . The maintenance of graphite more than 98 %, density of graphite weight of 1,0 g/sm3.

 Reinforcing is made by a foil of following kinds:

1. A leaf from steel 1.4301 (304) — nontoxical, not magnetic, unhardened, steady against corrosion steel.

 2. The leaf from steel 1.4401 (316) — differs from steel 1.4301 addition of 2-3 % of molybdenum. It considerably increases its ability to resist to corrosion and influence of acids. Steel 1.4401 has higher antimagnetic characteristics and  it is not magnetized at all.

 3. Other metals (Nickel sheets, copper, etc.)

 It is used in the petrochemical, mining industry, in pumps, flanges and armature.

  It is used in pair, mineral oil, heat-conducting oil, hydraulic oil, gasoline, water, sea water.

 Keeps constant elasticity and an equal surface under cyclic temperature conditions, does not grow old, to not become fragile. Does not show fluidity at low or heats. Long time does not lose compressibility and elasticity irrespective of temperature.
