There are many types and models of pens. According to the composition of the pen nib, it can be divided into three types: gold pen, gold pen, and ink pen pen.
Gold pen
The nib is made of gold alloy, the nib is soft, the elasticity is good, and the hand feels comfortable. However, the price of the gold pen is more expensive, the pen tip is soft, and it is not easy to master, and beginners should not use it.
Sheet metal pen
The nib does not contain gold, some nibs are gold-plated, and the nib is hard, but it is inexpensive and is a suitable tool for beginners to write.
The gold nib and the nib are more durable than the tip of the pen, and the secret is the small round on the tip of the pen. This small round grain is made of tantalum alloy and it is very hard and wear resistant. According to the experiment of Shanghai Jinxing Gold Pen Factory, if the gold pen tip and the pen tip are placed on the oil stone at the same time, after one hour, the gold pen tip wears only 0.07 mm, and the pen tip wears up to 5 mm!
Although the price difference is very different, the nibs of the nib are all alloys of special alloys, 钌, 钌! The reason why the smoothness differs is so much because of the different ways of polishing and fineness. So in a sense, the gold pen and the gold pen are the same. But the materials and feel are different, which leads to the price gap!
The ink contains a small amount of sulfuric acid, but this corrosive sulfuric acid poses a serious threat to the pen. If the tip of the pen is made of ordinary steel, it cannot withstand the corrosion of sulfuric acid and the life cannot be long. What metal can resist corrosion? Gold, enamel and stainless steel. Gold is a corrosion-resistant metal. People think of using it to make a pen tip. However, pure gold is too soft to be used directly for making a nib. The gold pen we usually say is the alloy. The tip of the better gold pen is marked with 14K, which means that it contains 58% of gold, and there are silver and copper: 12K, which means 50% gold. In this way, not only the hardness is improved, but the elasticity is also particularly good. The silver-white small round grain on the gold nib is called the golden grain. It is an alloy with bismuth and other rare metals that are particularly resistant to wear. Because when you write, you rely on it to cross the paper, and its life often has to “walk thousands of miles.” The sheet metal nib is made of stainless steel. Fortunately, the small rounds on the nib of the sheet metal are exactly the same as those on the gold pen. Therefore, the use of the gilt pen is similar to that of the gold pen, and the price is much cheaper. Therefore, the cheap and beautiful gold pen is very popular. Ordinary squirt pens and pens, which have no inlaid enamel on their nibs, and have a much shorter life.
Ink pen
The ink bag pen does not need to absorb ink, and a special ink bag can be inserted to be used.
