Aluminum LED Bulb PCB

1. LED lamps need materials with good heat dissipation, and aluminum has a much larger thermal conductivity than steel;

2. Aluminum profiles are easy to process, many shops can do it, and it is convenient to obtain materials;

3. There is a layer of dense alumina on the aluminum surface, whICh has a good anti-oxidative corrosion effect;

4. Finally, aluminum is cheaper than stainless steel, and the price is right.
