Secrets of the selection of materials for high-end metal badges
In recent years, the rush of collecting fever has made the collection value of badges more and more prominent, especially badges and medals made of metal materials have become the first choice for collectors.
The so-called metal badge is made of copper, iron, zinc alloy, gold and silver and other metal materials through a certain badge process. What kind of metal material is used for metal badges that are more high-end? The following is an introduction to the production of several common materials.
1. Metal material: iron
As one of our most common materials, iron is characterized by good hardness and low price. Electroplating or baking paint on the surface of the iron badge will have the texture of the copper badge, and the price is relatively low.
However, ferrous metal badges are susceptible to corrosion and cannot be placed in a humid space or transported by sea.
2. Metal material: copper
Copper (brass, red copper, red copper) is the metal of choice for making high-end badges. Among them, copper is used for the production of enamel badges, and brass and bronze are mainly used for the production of metal badges such as imitation enamel badges and painted badges. The texture of copper is relatively soft and extensible. It can be called the raw material for many metal badges. The produced metal badges have a beautiful appearance and high quality.
3. Metal material: zinc alloy
Zinc alloy has good casting performance and can be die-casted into small dense parts with complex shapes and thin walls. It is suitable for making three-dimensional badges and double-sided commemorative coins. Secondly, the metal badge made of zinc alloy metal material has a smooth surface, which can be electroplated, painted, sprayed, etc., and the zinc alloy has a low melting point, which can be melted and die-casted at 385°.
4. Metal material: stainless steel
Stainless steel, also called stainless iron, is mainly used to make printed badges, also called glue badges, and its thickness is generally 0.5mm and 0.8mm. The main features of stainless steel badges are strong corrosion resistance, durable metal and cost-effective, and its surface is printed with rich colors and outstanding decorative effects.
In badge production, in addition to metal badges made of copper, iron, zinc alloy, stainless steel, and stainless iron, there are also metal badges made of precious metals such as gold and silver and aluminum. Gold and silver badges are mainly used to make some high-end collectible badges. For example, we are most familiar with the medals of some international large-scale sports games, such as Olympic gold medals and Olympic silver medals. The value of such badges is obvious. In addition, some banks have become more common in recent years. Wealth management badge-type products, such as commemorative coins, are not only wealth management products, but also good badge collections.
