low price black lead , plumbago, Graphite Powder
low price black lead , plumbago, Graphite Powder soft and flexible, but not elastic which cannot be stretched. It is a black, naturally occurring form of carbon, just like diamonds, which are much harder and transparent. Graphite tends to stain surfaces that it comes into contact with. Although it is a nonmetal with a very high melting temperature, it does have some characteristics of metal, like it can conduct electricity .

2. Application
Industrial Uses | |
Dry Lubricant | Graphite tends to form in flat layers, where the atoms link together into lattices and stack on top of each other. These layers tend to trap air and water between them, which gives graphite a lubricating effect. Although graphite powder is dry (with air and water trapped inside it), it is very effective in lubricating joints and machine parts without the need of liquids like grease and oil. Because it holds up in very high temperatures, it is good for lubricating environments that get very hot. |
In Paint and E poxy | Graphite powder's lubricity makes it a popular additive to paint, epoxy and other coatings. It can help protect surfaces from scratches and other damage. It also makes a surface less prone to friction, which makes it a popular coating for the bottoms of boats built for speed. |
Pencils | The gray-black material in the core of a pencil that is sharpened to a point for writing is known as lead. But that material isn't lead at all. Instead, it is graphite powder blended with clay. |
