We summarize their characteristics in the following table, which can help you choose the suitable material for your project.
| Aspect | ZAMAK die casting | Aluminum Die Casting |
| Material | Zinc, aluminum, magnesium, and copper | Mainly aluminum |
| Melting Point | 380°C to 1446°C | 463°C to 671°C |
| Fluidity | Very high | High |
| Strength to Weight Ratio | High | Very high |
| Corrosion resistance | Moderate | Very high |
| Weight | Relatievly heavier | Lighter |
| Thermal conductivity | Lower | Higher |
| Electrical conductivity | Moderate | Higher |
| Hardness | 95 to 115 Brinell | 75 to 120 Brinell |
| Tensile Strength | 263 MPa to 317 MPa | 290MPa to 325MPa |
| Yield Strength | 200MPa to 317 MPa | 130 to 170 MPa |
From the above table, you can see that ZAMAK die-casting parts offer some benefits. It has a low melting point (except ZAMAK 2), fluidity, and excellent surface finish. So they are suitable for making hardware and toys. Besides, they also offer low thermal and electrical conductivity. Therefore, ZAMAK die-casting parts are prevalent in making many electronic gadgets.
On the other hand, aluminum die-casting parts give a high strength-to-weight ratio. Also, they offer high tensile strength, meaning you can use it to make many auto engine parts. Aluminum die-casting parts also provide high corrosion resistance. Because of this, they are also suitable in hard weather conditions. Moreover, aluminum offers high thermal and electric conductivity. So, they are also used in electrical appliances as well.
