Tungsten pen refill ball is a refill material made of tungsten steel alloy and is mainly used to make the nibs of high-end pens. It has the characteristics of high hardness, high density, high wear resistance, high corrosion resistance, etc., so it is widely used in high-end pen manufacturing industry. The tungsten pen core ball has the characteristics of high density, high hardness, high wear resistance, and high corrosion resistance, which can ensure smoothness when writing and improve writing comfort. The manufacturing process of tungsten pen refill balls is also very complicated and requires multiple processes and multiple grinding and polishing to complete. Therefore, the price of tungsten pen refill balls is relatively high.
