1. The difference in material:
Die-casting aluminum alloys generally use ADC12 or ALsi9cu3. Secondary aluminum alloys generally use 6063 or 6061.
2. The difference in appearance:
Die-casting aluminum is equivalent to the plastic injection molding process, which can produce any shape. The outer shell of the street lamp is generally made of die-casting aluminum. The shape of the equal cross-section used by the second-car aluminum has little change, such as the heat sink of the bulb lamp, and the aluminum profile of the door and window.
3. Thermal conductivity:
The general conductivity of die-casting aluminum is about 80-90W/M.K, while the thermal conductivity of car aluminum is about 180-190W/M.K.
4. Cost:
The cost of die-casting parts and car aluminum is relative, and they are all calculated by weight and machining. Calculate costs based on real-time material prices and labor. Relatively speaking, the cost of die-casting aluminum is higher, but the specific situation should be analyzed in detail.
5. Production efficiency:
The production efficiency of injection molding must be higher. Mass production generally produces more than 1,000 pieces a day, and the size is stable, and the shrinkage rate is 0.5%. Car aluminum machining has more ingredients, as the name implies, it is car aluminum. The efficiency is naturally lower.
6. Application:
Die-casting aluminum is generally widely used in automobiles, street lamps and the current mobile phone industry. Car aluminum is widely used in downlights, ceiling lights, doors and windows, etc.
