The heat dissipation and good appearance of aluminum alloy have exceeded the current plastic materials, and the weight of the counterweight itself cannot be replaced by plastic. So, do you know the difference between machined aluminum and die cast aluminum?

The following matters are introduced to you.

1. Material difference: ADC12 or ALsi9cu3 is usually used for aluminum die-casting alloy, while 6063 or 6061 is usually used for automotive aluminum.

2. Appearance difference: Aluminum die casting is equivalent to plastic injection molding process, and can produce any shape. The outer shell of the street lamp is usually aluminum die-casting. Aluminum has a smaller cross-sectional shape, such as radiators for light bulbs, aluminum profiles for doors and windows.

3. Thermal conductivity: The general thermal conductivity of aluminum die castings is about 80-90W/M.K, while the thermal conductivity of aluminum is about 180-190W/M.K.

4. Cost: The cost of die casting and aluminum is relatively high, calculated by weight and machining. Calculate costs based on real-time material prices and labor. Relatively speaking, the cost of aluminum die casting is higher, but the specific situation should be analyzed.

5. Production efficiency: The production efficiency of injection molding is definitely higher. It can be mass produced. Generally, it can produce more than 1,000 per day, with stable dimensions and a shrinkage rate of 0.5%. There are more ingredients in aluminum processing. As the name implies, it is an aluminum material for automobiles and has a low natural efficiency.
