1. When all configurations are the same, aluminum (usually alloy) fan blades are relatively better than plastic ones because the material is harder than plastic and the air outlet is stable and strong. The advantage of plastic is its low cost. This is the most critical. If it is not a high-power fan, the advantages of plastic are higher than if it is a high-power fan, the performance advantages of aluminum; the alloy will be clearly reflected. \x0d\ 2. At present, the blades of desktop fans are mainly made of iron blades, aluminum blades and plastic blades. Their advantages and disadvantages are as follows: \x0d\ Iron blades: do not deform after long-term use and have strength. large volume of air. However, if the blade quality is poor and the fan blade is not good, iThere is a risk of breakage and theft, injuring people, but this consumes more electricity. Aluminum foil: almost none; deformation after long-term use, large air volume, lighter weight, energy saving than iron sheets and plastic sheets more durable: lightweight and energy-saving, but it will deform after long-term use and seem windless; .It will distort again shortly after correction.
PC hardware.
The PC material of the electric fan blades is better. PC fan blades are tougher, stronger and more durable. Compared with stainless steel fan blades, PC fan blades are lighter and work at the same time. It is not easy to deform; stainless steel fan blades are relatively heavy, not easy to operate, and easily deformed.
