Current metal pens are mainly involved in the material: copper, steel, iron, aluminum …
1. Copper: also has many kinds, purple copper, brass, bronze, white copper.
We now make the pen processing with copper tubes, copper rods mostly refers to brass
Brass plasticity, wear resistance, on the other hand, the price cost compared to the purple copper will be much cheaper.
2. Stainless steel
3. Iron
4. Aluminum
Why we use different materials?
1. Mainly from the cost considerations, the current cost from high to low are copper, stainless steel, iron, aluminum.
2. The difficulty of processing requirements, for the general accessories we will use copper.
The simple distinction between various materials
1.From the color
Brass is an alloy composed of copper and zinc, yellow appearance
Stainless steel is generally stainless steel natural color, similar to silver gray
Iron and aluminum, generally silvery white
2. Cutting the hardness of the touch
Stainless steel hardness is the strongest, followed by copper and aluminum
Due to the cost advantage of aluminum, metal pens that are made of aluminum has gradually become the dominant
