The mechanical properties of carbon fiber graphite-reinforced plastic composites and grey cast iron are strongly influenced by the role of graphite in these materials. In this context, the term "(100%) graphite" is often loosely used to refer to a pure mixture of carbon reinforcement and resin , while the term "composite" is used for composite ...
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1 ] It is the most common cast iron and the most widely used cast material based on weight.
An achromatic gray is a gray color in which the red, green, and blue codes are exactly equal. The web colors gray, gainsboro, light gray, dark gray, and dim gray are all achromatic colors. A chromatic gray is a gray color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade ...
Diamond is clear and transparent, but graphite is black and opaque. Diamond is the hardest mineral known (10 on the Mohs scale), but graphite is one of the softest (1–2 on Mohs scale). Diamond is the ultimate abrasive, but graphite is soft and is a very good lubricant.
Davy's gray is a dark gray color, made from powdered slate, iron oxide and carbon black named for Henry Davy. [9] [10] The first recorded use of Davy's gray as a color name in English was in the 19th century (precise date uncertain). [11]
Graphite pencils are made of a mixture of clay and graphite and their darkness varies from black to light grey. A higher amount of clay added to the pencil makes it harder, leaving lighter marks. [59] [60] [61] There is a wide range of grades available, mainly for artists who are interested in creating a full range of tones from light grey to ...

The common defining characteristic of this group of materials is the shape of the graphite. In ductile irons, graphite is in the form of nodules rather than flakes as in grey iron . Whereas sharp graphite flakes create stress concentration points within the metal matrix, rounded nodules inhibit the creation of cracks, thus providing the ...
