How hard is a 9h pencil?

The hardest pencil can go up to 3 Mohs and is noticeably harder then most other pencils. To put this in perspective, a human finger nail is around 2.5 Mohs. So, even a 9H grading on a coating would be about 3 Mohs in comparison.

Are B or H pencils harder?

"H" pencils feature harder graphite. (The "H" stands for "hard".) "B" pencils feature softer graphite. (The "B" stands for "black".)

Are H pencils the hardest pencils?

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.

How hard is 9H ceramic coating?

Essentially, a 9H-rated nano ceramic coating has the ability to resist the scratching strength of a 9H pencil, the sharpest and hardest pencil on the planet.

What is 9H hardness?

The suffix means the hardness of a pencil. To find a rating, you use the pencil test, which compares the relative hardness of a screen. When a manufacturer claims that their screen is 9h, it means the screen can resist scratches from the hardest pencil.

Understanding PENCIL GRADES - What you NEED to know

Is there such a thing as 10H hardness?

H is for “Hardness” and follows a scale from H to 10H with 10H being the hardest. 10H is also the lightest as it is hardest and would leave the least amount of graphite on the surface.

What is an F pencil?

F. The letter 'F' indicates a pencil that sharpens to a fine point. HB. A combination of letters, for example, 'HB' means the pencil is hard and black. 'HB' pencils are considered the middle point of pencil lead grades.

What does 9B mean in pencils?

The softer the pencil, the smoother the graphite. The number beside each letter represents the level of hardness or softness. So a 9B pencil is softer/darker than a 2B, while an 8H will be harder/lighter than a 3H. Here's a list of pencil grades in order from lightest to darkest or hardest to softest.

Do number 1 pencils exist?

Lead pencils are graded on a scale from No. 1 to No. 4 based on how much graphite is inside the core. The #1 pencils are the softest, while the #4 pencils are the hardest.

Is 9b the darkest pencil?

For graphite drawing pencils on the market, the lightest is 6H, while the darkest available is 8B. The higher the number in each grade, the lighter or darker it is.

Is there a 10B pencil?

The 10B pencil is one of the softest and darkest graphite pencils there is. Artists use it for shading and creating a sense of three-dimensional form by graduations of tone.

What is the strongest pencil lead?

The Hardest Mechanical Pencil Lead

4H is the hardest mechanical pencil lead grade. It is used for drafting and technical drawing. It is not a popular grade; therefore, manufacturers only make it for 0.5 mm mechanical pencils. Pentel, Pilot, and Uni are the three leading manufacturers that make 4H lead refills.

Which lead is harder H or HB?

Graphite pencils are classified as either soft black (B), hard (H), hard black (HB), and firm (F). The degree of soft black, hard, hard black, and firm are then further classified by numbers, the higher the number the higher the intensity.

What is the hardest drawing pencil?

The 9H is typically the hardest and lightest graphite pencil available. An HB pencil falls in the middle of the scale. For drawing, it's still reasonably hard. The more B's, the softer a pencil is.

Is H or HB darker?

The HB Scale

Most pencil manufacturers utilize the HB grading system. The letter “H” is used to indicate the hardness of a pencil's mark. The letter “B” is used to indicate the blackness of a pencil's mark (a darker mark means a softer lead).

What are 3H pencils used for?

3H. 3H is an extremely light shade of gray that leaves a very light imprint on paper. It can be a great choice for sketches where you need to add light shades or slightly fill in the empty spaces with a pencil.

What is H and B in pencils?

The degree of hardness of a pencil is printed on the pencil.

B stands for "black". These pencils are soft. H stands for "hard". HB stands for "hard black", which means "medium hard". F stands for "firm".

What is the darkest writing pencil?

B9 is the softest and darkest. 9H is the lightest and hardest graphite pencil. So a B6 is softer and darker than a B2.

What is a no2 pencil?

A No. 2 pencil is towards the middle when it comes to the hardness of lead (graphite) and the darkness of the shade. If a pencil has a number higher than 2 it means it has a harder graphite core, a harder point, and a lighter shade. These pencils are often used by engineers or architects.

Which pencil is the easiest to erase?

This is, in practice true because the middle range of pencils, erring the softer side, had lead that is light enough that it doesn't dig into the paper and isn't so soft that is smudges without ever being fully removed. The pencils that, generally speaking, erase the best are in the 2B, 3B and 4B grades.

What is the thickest pencil lead?

5.6 mm Mechanical Pencil Lead. 5.6 mm is the largest diameter of pencil lead used for drawing, sketching, and shading.

How hard is a 5H pencil?

The test is repeated with increasingly harder pencils. Eventually a pencil with hardness 5H is used, but leaves a very slight mark on the surface. The 5H pencil is the first one to permanently damage the surface. Therefore, the highest hardness grade on the pencil scale would be 4H.

What is 6H hardness?

The hardest is a 10H, followed by 9H, 8H, 7H, 6H, 5H, 4H, 3H, 2H, and H. F is the middle of the hardness scale; then comes HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, and 9B, which is the softest. The most commonly used writing pencil is the #2 (HB grade), which is fairly soft, contains more graphite, and leaves a dark mark.

Which pencil are hardest 8H 7H 6H 3H?

The 'H' stands for hardness, the 'B' stands for blackness, and HB is for hard and black pencils. The hardest is a 9H, followed by 8H, 7H, 6H, 5H, 4H, 3H, 2H, and H.
