1.On difference of materials
Casting aluminum alloy are made of ADC12 or AlSi9Cu3,while mechanical working aluminum 6063 or 6061 aluminum.
2.On differences of shaping
Through die-casting,aluminum alloy be can shaped for different forms ,which equivalents to plastic injection molding process.For instance,street lamp's shells are usually made of die-casting aluminum.While due to cross section shapes of machine working aluminum,they are mainly used for heat sink of bulbs,doors and windows .
3.On differences of conductivity
The general conductivity of die-casting aluminum is about 80-90W / M.K, while the car-aluminum thermal conductivity is about 180-190W / M.K.
4.On difference of costs
The cost of die-casting aluminum and mechanical aluminum is just relatively.Both are calculated by weight and mechanical working.Generally speaking,the cost of die-casting aluminum is higher.
5.On difference of producing efficiency
Producing efficiency of die-casting aluminum is certainly much higher than that of meachniacl working aluminum.
6.On difference of application
Die-cast aluminum is widely used in the automobile industry,street lights and the mobile phone industry.Mechanicalworking aluminum in the down light,ceiling,lamps as well as doors and windows etc.
