Have you purchased LED luminaires before? Have you heard from your supplier about die-casting aluminum ADC12 and extrusion/cold-forging 1070 aluminum? What’s the difference? Which is better?
The following will be your interested.
1.Features of ADC12-Die casting aluminum
ADC12 is aluminum alloy with purity of 77%~86%, mostly used for die-casting components,cost-efficient and facilitates manufacturing processes.
ADC12 offers good corrosion resistance and outstanding mechanical properties,and it has higher levels of silicon, and lower levels of copper.
- Features of 1070 extrusion aluminum
1070 aluminum has purity up to 99.7%, which could be called as pure aluminum.It has higher resistance to chemical corrosion and crack resistance.
When we talking about luminaires, we mostly concern the thermal performance of the heat sink,which is also the main body of the lamp
The following show the thermal performance of ADC12 and 1070 aluminum
Thermal Performance of 1070 Aluminum
Thermal Performance of ADC12 Aluminum
As you can see, 1070 aluminum offer much better thermal performance than ADC12 aluminum alloy, especially the thermal conductivity.
So, when we develop high power sports light, especially the 1200W,1500W model, we always use 1070 aluminum to process the heat sink body.
