The heat dissipation and good appearance performance of aluminum alloy have surpassed the current plastic materials, and the weight brought by its own weight cannot be replaced by plastic. What is the difference between machined aluminum and die-cast aluminum? Southern Aluminum believes that this is the distinction.
1. The difference in materials:
Die-cast aluminum alloy generally uses ADC12 or ALsi9cu3, while processed aluminum generally uses 6063 or 6061.
2. The difference in appearance:
Die-cast aluminum is equivalent to the plastic injection molding process, which can be made into any shape. The housing on the street lamp is generally made of die-cast aluminum. The shape of the constant cross-section used in processed aluminum has little change, such as the heat sink of the bulb lamp, and the aluminum profile of doors and windows.
3. Thermal conductivity:
The general conductivity of die-cast aluminum is about 80-90W/M.K, while the thermal conductivity of processed aluminum is about 180-190W/M.K.
4. Cost:
The cost of die-casting and machining aluminum is relative, and both are calculated by weight and machining. Calculate the cost based on real-time material prices and labor. Relatively speaking, the cost of die-cast aluminum is higher, but the specific situation needs to be analyzed in detail.
5. Production efficiency:
The production efficiency of injection molding is definitely higher. Mass production usually produces more than 1,000 a day, and the size is stable, and the shrinkage rate is 0.5%. Machining aluminum has more ingredients, just as the name implies, it is processed aluminum. The efficiency is naturally lower.
6. Application:
Die-cast aluminum is generally widely used in automobiles, street lights and the current mobile phone industry, and processed aluminum is widely used in downlights, ceiling lights, doors and windows, and so on.
