Silver additive effect better than copper, silver-plated copper better

Can also be attached to the metal-plated alloy. In the binding agent is added in the metal additive is silver, copper or silver plated copper. Amount (volume ratio) of 30 to 50 gung,  synthetic diamond  effect is better than copper, silver-plated copper better. Metal powder size 325. In the binding agent is added to the solid lubricant graphite, fluorinated graphite, hexagonal boron nitride, tungsten disulfide, disulfide key diselenide ni. Amount (volume ratio) 10,20 intestine. These  abrasive grinding  are having a layer of organic crystal lattice structure ming, between atoms in the same layer by the strong covalent binding force or ionic strength, and interlaminar only weak van der Waals force.
