Details of car aluminum and die cast aluminum
Aluminum alloy heat dissipation and good appearance has exceeded the current plastic material, and the weight of its own weight is not a substitute for plastic.
1 material aspect: die casting aluminum alloy generally use ADC12 or ALsi9cu3. Two car aluminum general use 6063 or 6061
2 the appearance of the distinction: the equivalent of plastic injection molding process, you can create any shape; street lamp above the shell is generally used in die casting aluminum. Section two of the car aluminum shape, small changes, such as fin bulb lamp, aluminum doors and windows.
3. Thermal conductivity: the general conduct of the die cast aluminum is about 90W/M.K, while the thermal conductivity of the car is about 180 - 190W/M.K.
4 cost: the cost of die casting and aluminum is relative, which is calculated by weight and machining. 5 production efficiency: injection molding production efficiency must be higher, mass production, the production of more than one day in general more than 1000, and the size is stable, the rate of contraction in 0.5%. Car aluminum machine processing more than a few, as the name suggests is the car aluminum.
Application.: Die Casting Aluminum in automobile, streetlights, and now the mobile phone industry application widely, the car aluminum downright, ceiling lamps and windows, etc. which are widely used in.
