1. The difference in materials: Die-casting aluminum alloy generally uses ADC12 or ALsi9cu3. Two-car aluminum generally adopts 6063 or 6061.
2. The difference in appearance: Die-cast aluminum is equivalent to the plastic injection molding process, can create any shape, the shell above the street lamp is generally die-cast aluminum. The shape of the equal cross section adopted by the two-vehicle 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-cast aluminum is about 80-90W/MK, while the thermal conductivity of car aluminum is about 180-190W/MK.
4. Cost: The cost of die castings and car aluminum is relative, both calculated by weight and machining. Calculate costs based on real-time material prices and manual calculations. Relatively speaking, the cost of die-casting aluminum is higher, but the specific situation should be analyzed.
5. Production efficiency: The production efficiency of injection molding is certainly higher, and the batch production is generally more than 1,000 in a day, and the dimensional stability is stable. The shrinkage rate is 0.5%. The composition of the car aluminum machining more, as the name suggests is the car aluminum. The efficiency is naturally lower.
6. Application: Die-cast aluminum is widely used in automobiles, street lamps and the current mobile phone industry. Aluminum cars are widely used in downlights, ceiling lights, and doors and windows.
