In recent years, the gust of collection fever has made the collection value of enamel pins more and more prominent, especially the hard enamel pins and soft enamel pins made of metal have become the first choice for collectors to collect and commemorate.
The so-called enamel pin is made of copper, iron, zinc alloy and other metal materials, which are made by a certain badge process. What kind of metal material is used to make the metal badge more high-end? The following is an introduction to several common materials.
No.1 Enamel pin that made of Iron
Iron is one of our most common materials. It has the characteristics of good hardness and relatively cheap price. Therefore, the price of enamel pin made of iron is much cheaper, and the effect of electroplating and coloring on the surface of iron pins Similar to bronze pins. Another feature of iron is that it can be directly attracted by magnets, and there is no need to bury a strong magnet on the back of the badge.
However, one disadvantage of custom-made iron metal pin is that if you go by sea for a long time, it is easy to rust. If you use it in contact with water, it is recommended not to choose iron pins.
No.2 Enamel pin that made of copper
Copper (the commonly used copper for pins includes bronze and red copper) is the preferred metal for high-end pin, and among them, red copper is used for the production of real hard enamel pin, and bronze is mainly used for custom-made metal pin such as imitation enamel pin and printing pins.
Copper, a metal material, is relatively soft and heavy. It uses more materials to make metal pins with a sense of weight, but the unit price is relatively high. The metal pins produced are beautiful in appearance and high in quality. 1.2mm, 1.5mm or 1.8mm, the thickness of the medallion is generally 3mm.
No.3 Enamel pin that made of zinc alloy
Zinc alloy is the most widely used material for die-casting metal pins. Zinc alloy has several characteristics that are very suitable for metal badge customization, suitable for making three-dimensional badges and double-sided commemorative coins.
The features of zinc alloy:
1- Good casting performance, it can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.
2 – The surface can be electroplated, painted, sprayed and other processes.
3- It does not attract iron and does not stick to the mold during die casting.
4 – Good mechanical and wear resistance at room temperature.
5 – Low melting point, melts at 385 degrees, easy to die casting, etc.
