Which of the following is a good lubricant ?
Alloy of carbon and iron
Graphite is best suited for lubrication in air. It is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant. This slippery quality also makes graphite a good material for pencil lead because it easily sloughs off onto paper.
