The materials used for craft gifts processing are zinc alloy, copper, iron, and aluminum. Different materials require different processing techniques. This article lists the processing techniques of different materials in a table.
| Material | Characteristics | Processing Technic |
| zinc alloy | 1. White with a grayish color 2. Density: 6.7 g/cm3 3. Low melting point 4. Good fluidity and easy to cast, good 3D and hollowing effects 5. Corrosion-resistant and not easy to rust 6. Usually the thickness is not less than 2mm 7. Cheaper than copper 8. The mold fee for die-casting will be higher than that of stamped copper and iron |
Die-casting |
| brass | 1. The natural color is brass 2. Density: 8.9 g/cm3 3. High density and few sand holes 4. More expensive than zinc alloy and iron 5. Can be used as a bite plate 6. If the thickness exceeds 3mm, it will be more difficult to press, and it will be expensive to press twice |
Stampping+Cutting |
| iron | 1. Natural grayish white 2. Density: 7.8 g/cm3 3. Cheaper than copper, easy to rust 4. If the thickness exceeds 4mm, it will be more difficult to press 5. The density is relatively small compared to copper, with more sand holes |

| aluminum | 1. Natural silvery white 2. Density: 2.7 g/cm3 3. Low density, relatively light 4. Suitable for anodizing |
