The Difference Between Machined Aluminum And Die-casting Aluminum
Apr 21, 2018

1, the difference in material:

Die casting aluminum alloys generally use ADC12 or ALsi9cu3, while car aluminum generally uses 6063 or 6061..

2, the difference in appearance:

Die casting aluminum is equivalent to plastic injection molding technology, which can create any shape. The housing on the street lamp usually uses die-casting aluminum. The shape of the aluminum cross section is smaller, such as the heat sink of the bulb, the aluminum profile of the door and window.

3, thermal conductivity:

The general conductivity of die cast aluminum is about 80 - 90W/M.K, while the aluminum thermal conductivity of vehicle is about 180 - 190W/M.K.

4, cost:

The cost of die castings and vehicle aluminum is relative. They are all calculated by weight and machining. According to real-time material price and manual calculation cost. Comparatively speaking, the cost of die-casting aluminum is higher, but the specific situation needs to be analyzed concretely.

5, production efficiency:

The production efficiency of injection molding is definitely higher. Mass production usually produces more than 1000 products a day, and the size is stable, and the shrinkage rate is 0.5%. There are more ingredients in car aluminum processing. As the name suggests, the car is aluminum and the efficiency is lower.

6, application:

Die cast aluminum is widely used in automobiles, street lamps and the mobile phone industry nowadays. Car aluminum has many applications in down lights, ceiling lights, doors and windows and so on.
