There will be some differences in the price of shaded-pole motor blades made of different materials, which mainly depends on the following factors:

1. Material cost: The cost of different materials varies greatly. Generally speaking, the cost of plastic blades is relatively low, aluminum alloy is slightly higher, and the cost of stainless steel and composite materials may be higher. This is because the raw material prices, processing costs, and supply chain of different materials are different.

2. Demand and market competition: The demand for a certain material and the market competition situation will also affect the price. If the demand for a certain material is large and the market competition is fierce, suppliers may lower prices to attract customers.

3. Special properties and processing requirements: For a certain material, it has special properties or requires special processing technology, which may lead to its higher price. For example: stainless steel has good corrosion resistance, but the processing and manufacturing process may be more complicated, so the price is relatively high.

It should be noted that the price depends not only on the material itself, but also on other factors, such as size, shape, design requirements, and fixed investment. Therefore, when choosing a shaded-pole motor blade, in addition to considering the price factor, the performance and applicability of the material should also be considered comprehensively to meet the needs of specific applications.
