Blade material
Common blade materials have a variety of vacuum pumps on the market, graphite (carbon), resin blade, glass fiber, carbon fiber, aluminum and other materials. But using different brands in different types of vacuum pumps, the materials are different.
Graphite (carbon), the main advantages are: relatively low prices, environmental protection, low noise and less friction to the pump body. Disadvantages are easy to break, no wear.
Main advantages of aluminium alloys are: abrasion resistance, but the price is relatively high, noisy, great friction on the pump body.
