Die casting materials and properties
When selecting raw materials for die casting products, a reasonable choice should be made according to factors such as the environment, processing and material properties. At present, the commonly used die casting material include aluminum, zinc and magnesium alloy, among which aluminum alloy is the mostly acceptable material.
Aluminum alloy
1. The density of aluminum alloy is small, only one-third of that of iron and copper material. High specific strength and stiffness are the outstanding properties of aluminum alloy.
2. Aluminum alloy has good electrical and thermal conductivity,
3. Aluminum alloy has good oxidation resistance.
4. Aluminum alloy has good die casting properties. The die-casting process of aluminum alloy is relatively simple, and the cutting performance is good.
5. The high-temperature mechanical properties of aluminum alloys are good, and they can also maintain good mechanical properties in low-temperature environments.
Zinc alloy
1. Just like aluminum alloys, zinc alloys have excellent casting properties and mechanical properties, and are wildly used in hardware, locks and other products.
2. Zinc alloy has excellent electrical properties. Its good electromagnetic shielding performance makes it popular in the field of electronic appliances.
3. Zinc alloys can be processed into products with complex structure by die casting process.
4. The surface of the zinc alloy product is smooth, and no surface treatment is needed.
Magnesium alloy
1. Magnesium alloy has strong mechanical properties, its specific strength and stiffness are better than aluminum alloy and steel, and it is an excellent lightweight metal material.
2. Magnesium alloys have good ductility, which can make the structure of the product more flexible.
3. Good machining performance and good cutting effect.
4. Magnesium alloy products require specific surface treatment to delay the oxidation of the material in the air.
