The heat dissipation and good appearance of aluminum alloy have surpassed the current plastic materials, and the weight brought by its own weight cannot be replaced by plastic. 7-swords believes that aluminum alloy has the following six advantages
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 injection molding process of plastics and can be made into any shape. The shells on street lamps are 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 automotive aluminum is about 180-190W/M.K.
The cost of die-casting parts and car aluminum is relative, and they are all calculated according to 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, 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.
Die-casting aluminum is generally widely used in automobiles, street lamps, and the current mobile phone industry. Automotive aluminum is widely used in downlights, ceiling lights, doors and windows, etc.
