Metal MEDALS are most commonly used for several main reasons:

1. ** Symbolism ** : Metals, especially precious metals such as gold, silver and copper, represent value, wealth and achievement in many cultures. They are used as awards and can convey the importance of what the winner has achieved.

2. ** Durability ** : Metal materials are usually more durable than other materials and can be stored for a long time without damage or deterioration. This makes the metal medal suitable as a lasting souvenir that the winner can treasure for many years to come.

3. ** Aesthetics ** : Metal can be processed by polishing, engraving, etching and other processes to present a very beautiful appearance. These processing methods allow the MEDALS to have a unique design and high texture, thus enhancing their visual appeal.

4. ** Tradition and Custom ** : Historically, the use of metal to make MEDALS and decorations has a long history. For example, gold, silver and copper have been used in the Olympic Games since 1904 to distinguish the different medal classes. Over time, this practice became an international standard and tradition.

5. ** Customizability ** : Metal MEDALS can be customized according to needs, including the addition of a company logo, special patterns or text messages to make it more suitable for the theme or purpose of a particular event.

6. ** Economic cost ** : Although the precious metal itself is of high value, the overall cost is still controllable considering the small size of the medal and the efficiency of mass production. For awards that are not at the highest level, more affordable metal options can also be selected, such as gold plated, stainless steel, etc.

7. ** Environmental considerations ** : Modern metal MEDALS are sometimes made of recycled materials, which is not only in line with the concept of sustainable development, but also adds a special layer of meaning to the medal.

In summary, due to the above advantages, metal MEDALS have become one of the most popular choices in various competitions, celebrations and other formal occasions.
