What material are fan blades made of?
The most common material for commercial fan blades is metal (aluminum or steel) or plastic (polypropylene). Yet some companies are also producing fans using nylon textile and fiberglass-reinforced polyester. Metal blade fans are a popular choice for many consumers due to their durability and longevity. They are typically made from materials such as steel, aluminium, or copper, which can withstand wear and tear over time.The most common material for commercial fan blades is metal (aluminum or steel) or plastic (polypropylene). Yet some companies are also producing fans using nylon textile and fiberglass-reinforced polyester.Two of the most common materials used in ceiling fan blades are ABS (Acrylonitrile Butadiene Styrene) and wood. Both materials offer unique benefits, and the choice between the two largely depends on your specific needs and preferences.
What metal is used in turbine blades?
Turbine blades are made of superalloys that contain more than 50% of nickel and allow solidification of the whole blade as a single crystal (find out more about why here). The image shows an electron microscope image of a single crystal. Wind energy farms looking to stand up a wind turbine need to note in their budget a single wind turbine blade goes for $2. While using fewer, larger turbines can be beneficial, the cost rises as the wind turbine blade sizes increase.For example, a turbine blade made of single crystal superalloy can cost as much $30,000 [12].A typical wind turbine blade can cost around $154,000 (NREL) but this includes the costs of materials, the wind turbine manufacturers’ labor costs, and maintenance. The initial purchase cost is around half of this total, at $73,600.
What materials are fan blades made of?
The material used in industrial propellers or fan blades is generally fabricated steel, cast or fabricated aluminum, fabricated stainless steel, or other exotic metals. Plastic propellers have become common, but typically only in commercial or residential fans. Using a special vacuum casting furnace with tightly controlled temperature zones, they poured molten superalloy into a ceramic mold and used a controlled cooling process to directionally align the grains along the span of the turbine blade, making it much stronger.The most important requirement for the gas turbine blade is to have high creep resistance at a higher temperature. To cope with this, exotic materials like superalloys of nickel-based alloy, cobalt-based alloy or iron-based alloys are well suited.Modern turbine blades often use nickel-based superalloys that incorporate chromium, cobalt, and rhenium. Aside from alloy improvements, a major breakthrough was the development of directional solidification (DS) and single crystal (SC) production methods.Since the 1950s, in high temperature regions of the turbine, special blades and vanes are made from a combination of metals based on high-melting-point nickel. This material is called a “superalloy” because it retains strength and resists oxidation at extreme temperatures.

Why is titanium used for fan blades?
Indeed, material properties like strength, stiffness, weight, and thermal stability directly influence the performance, efficiency, and durability of the blades. Conventionally, titanium and aluminium alloys are used for fan blades due to their specific stiffnesses and specific strengths [4]. GRP blades have a good to excellent corrosion resistance against 78% of known chemicals. Aluminium has a good to excellent corrosion resistance against 63% of known chemicals. Typical axial fan blade materials supplied by Fantech include GRP, Aluminium, Nylon and Anti-Static Plastic.One of the most common materials is carbon steel but we offer fans constructed from mill run galvanized steel, aluminum, and various grades of stainless steels.
