What pencil has the hardest graphite?
9H
B9 is the softest and darkest. 9H is the lightest and hardest graphite pencil. So a B6 is softer and darker than a B2. An 6H is harder and lighter than a 2H and much harder and lighter than a HB or a B pencil.
What pencil has the hardest lead?
The numbers indicate the hardness or softness of the pencil within their particular range. The H pencil range: The 9H pencil is the hardest and H pencil is the softest. The B pencil range: The 9B pencil is the softest, and the B pencil is the hardest.
Which pencil lead is harder H or HB?
The letter “F” is also used to indicate that the pencil sharpens to a fine point. Today, however, most pencils using the HB system are designated by a number such as 2B, 4B or 2H to indicate the degree of hardness. For example, a 4B would be softer than a 2B and a 3H harder than an H.
What pencil lead is the softest and which is the hardest?
2B, 3B and 4B are increasingly soft. Further up the range, 9B is the very softest lead available, but so soft and crumbly that it’s rarely used. Anything over 4B is probably too soft for most people’s day-to-day use. Harder leads than HB get H ratings.
What is the darkest writing pencil lead?
The Staedtler Mars Lumograph 12B pencil is the graphite pencil that has the highest B rating of any pencil on the graphite scale. Which in theory makes it the darkest wooden drawing pencil that there is.
What’s the hardness of graphite?

Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10. No other naturally occurring substance has a hardness of 10.
What is graphite hardness?
Flexible non-elastic, sectile. Mohs scale hardness. 1–3.
What is the darkest graphite pencil?

What is a 4B pencil?
“B” pencils feature softer graphite. (The “B” stands for “black”.) The number found in front of the letter reveals just how soft or hard the pencil is. In other words, a “4H” pencil is harder than a “2H” pencil while a “4B” pencil is softer than a “2B” pencil.
What is the hardness of pencil lead?
pencil hardness. Non-standard but well-accepted measure of the hardness of pencil leads (made of different proportions of graphite and clay), commonly ranging from 6B (maximum graphite , hence softest) to 6H (least amount of graphite, hence the hardest) with HB (roughly equal amounts of graphite and clay, hence medium soft/hard) in the middle.
What are pencil lead grades?
The grades for the graphite (pencil lead) range from hard to soft. In general, hard pencils draw light lines; soft pencils draw darker and wider lines. The hardest standard grade for drafting/drawing pencils is 9H. The softest pencil is grade 6B.
What are the grades of pencils?
There is 22 different grades, ranging from 10H to 10B. H pencils are harder, more precise, lighter, and B pencils are softer, waxy, and produce richer, bolder lines. The HB and F grades (which are in the middle) are most commonly used for everyday sketching and writing.
What is the size of pencil lead?
The standard wooden artists’ pencil is 7 inches long with a lead 2 mm in diameter. Two millimeter leads are also used in lead holders, popular with draftsmen.
