When selecting raw materials for ceiling fan blades, material hardness, self-weight, durability, and processing performance are the core elements that manufacturers focus on. Among various aluminum alloy materials, 1100 H18 aluminum plate has now become the mainstream choice in the global ceiling fan manufacturing industry. This article will detail its core advantages and explain why it is the ideal material for making fan blades.
1100 series belongs to industrial pure aluminum, with an aluminum content of over 99%, boasting excellent rust resistance and corrosion resistance. Ceiling fans are widely used in humid environments such as homes, factories, and shops. Blades made of 1100 aluminum plate are resistant to oxidation and rust even after long-term use, ensuring long-term stability in appearance and operational performance.
H18 is in a fully hardened state, where the aluminum plate exhibits excellent tensile strength and surface hardness. When the blades rotate at high speed, they are less prone to deformation and warping, and do not generate abnormal vibrations. This effectively reduces overall machine jitter and operating noise, ensuring smooth operation of the ceiling fan, while also extending the service life of the entire machine.
Aluminum is inherently lightweight. Compared to steel materials, 1100 H18 aluminum sheets can significantly reduce the self-weight of fan blades. As the weight of the blades decreases, the load on the motor also decreases, which not only reduces power consumption and achieves energy-saving effects, but also reduces wear and tear on the internal components of the motor.
When mass producing ceiling fan blades, an integrated process involving stamping, bending, and stretching is required. The 1100 H18 aluminum plate, which combines hardness and plasticity, can be smoothly processed into blades of various shapes. It is resistant to cracking during stamping and is suitable for automated mass production, helping manufacturers improve production efficiency and control production costs.
The rolled 1100 H18 aluminum plate has a flat and smooth surface. When made into blades, it has lower wind resistance during operation, produces a large amount of air output, and runs quietly, greatly enhancing the user experience. At the same time, the regular plate surface is also convenient for later painting and surface decoration treatment.
With multiple advantages such as high purity, full hardness, lightweight, easy processing, and low wind resistance, 1100 H18 aluminum plate fully meets the various requirements for ceiling fan blades. For manufacturers who pursue stable quality, controllable cost, and reliable performance, it is undoubtedly the best raw material for manufacturing ceiling fan blades.
