Pen barrel identification
The hardness mark of pencil lead core generally uses “H” to indicate a hard pencil, “B” to indicate a soft pencil, “HB” to indicate a pencil with moderate hardness, and “F” to indicate a pencil with a hardness between HB and H.
Arrangement (from soft to hard) 9B, 8B, 7B, 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H, 10H, etc. Hardness level.
The larger the number in front of H, the harder the lead and the lighter the color. The larger the number in front of B, the softer the lead and the darker the color. The classification of pencil shafts is based on the amount of graphite in the pen core. Among them, H type pencils have relatively high pen core hardness, which is suitable for objects with relatively hard or clear interfaces, such as woodworking markings, field drawings, etc.; HB type pencils have moderate hardness, which is suitable for general writing or writing. For contours; type B pencils, with relatively soft refills, suitable for painting, and can also be used to fill in some machine-recognizable cards. For example, we often use 2B pencils to fill in answer sheets. In addition, there is a common color pencil shaft, also known as colored pencils, which are mainly used for drawing.
