What is the material composition of Apple double layer pen tip?

The material composition of the Apple double layer pen tip mainly consists of two parts: outer metal material and inner plastic material.

External metal material: The external metal material of the Apple double layer pen tip is usually made of stainless steel or aluminum alloy. These metal materials have high hardness and wear resistance, which can provide better writing experience and stability. They can also increase the weight of the pen tip, making it more in line with traditional writing habits.

Internal plastic material: The internal plastic material of the Apple double layer pen tip usually uses engineering plastics, such as polycarbonate or nylon. These plastic materials have good insulation and corrosion resistance, can protect the internal metal materials from the external environment, and can also play a certain buffering role to reduce vibration and noise when writing.

In addition, the metal and plastic materials of the Apple double layer pen tip are usually connected mechanically or chemically to ensure the stability and reliability of its overall structure.

In general, the material composition design of the Apple double layer pen tip can provide good writing performance and durability, and is also in line with Apple's consistent focus on details and user experience.
