Carbon pen is a kind of gel pen, which is very consistent with fountain pen, so it is also called signature pen. The inner core ink of carbon pen is made of carbon, which is cheaper than simple fading, does not print, and the overall copying is smoother. The ink in the carbon refill is mainly created by graphite, which is one of the quiet materials in nature.

The ink in the carbon refill is mainly composed of graphite, which is one of the most stable substances in nature. Therefore, writing with a carbon pen will not be blurred because it is kept for too long. Pen holder and pen cover are made of plastic injection molding, stainless steel stamping and polishing. The nib is divided into two types: cannonball type and needle tube type, which are made of copper alloy, stainless steel or engineering plastic respectively. Most balls are made of stainless steel, cemented carbide or alumina.

The difference between carbon pen and gel pen;

First, conceptual differences.

1, carbon pen: The ink in the carbon refill is mainly composed of graphite, which is one of the most stable substances in nature. Therefore, writing with a carbon pen will not be blurred because it is kept for too long.

2. Gel pen: A ballpoint pen with a viscosity between water and oil is called a gel pen. Gel pen originated in Japan and is a novel writing tool that is popular all over the world. Gel pen has the advantages of fountain pen and ballpoint pen, and it feels comfortable to write.

Second, the difference in oil content.

1, carbon pen: The oil range is relatively large, and the ink is oily, so it belongs to an ink pen with high oil content.

2, gel pen: ink is a neutral colloid, written as liquid rather than oily pigment of ballpoint pen, so some people call it fountain pen.

Third, the differences in use occasions.

1, carbon pen: generally oily, insoluble in water, so it is generally used in formal occasions. In addition, it would be great if you used an oil pen to write on the burned CD. If you want to erase the words written by an oily pen, you must rely on alcohol.

2, gel pen: "ink" is more "easy-going", widely used in schools, institutions, companies and other daily office occasions.
