Wheelchair frame material

The wheelchair frame is the "skeleton" of the wheelchair. The wheelchairs we can see on the market at present, the frame materials are mainly divided into: aluminum alloy material, carbon steel material, magnesium alloy material, and carbon fiber material. We can analyze the difference between the four materials from the following aspects.

Because there are differences in raw materials such as aluminum alloy, carbon steel, magnesium alloy, and carbon fiber, the prices of electric wheelchairs of corresponding materials will also vary.

Price: carbon fiber>magnesium alloy>aluminum alloy>carbon steel

Secondly, because most of the electric wheelchairs are used by the elderly, in some special scenarios, the wheelchair needs to be moved, so the weight of the product has to be considered. The weight of a carbon steel electric wheelchair is about 40KG, and the weight of an aluminum alloy electric wheelchair is about 35KG. For a wheelchair made of magnesium alloy, take the Guardian 205 of an e-commerce platform as an example. The body weight is only 14KG, so the carbon fiber wheelchair The weight is even lighter, only about 10KG.

Weight: carbon steel>aluminum alloy>magnesium alloy>carbon fiber

Then there is the problem of the service life of the wheelchairs made of four materials. We can analyze it from the properties of the three materials.

carbon steel:

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contain a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

Aluminum alloy:

Aluminum alloy has low density, high strength, good plasticity and good corrosion resistance.

magnesium alloy:

Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density, high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good corrosion resistance of organic matter and alkali. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. It is the lightest metal among practical metals, with high strength and high rigidity.

carbon fiber:

Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%, which has good load-bearing capacity and durability, but has weak impact resistance.

in conclusion:

Although the price of carbon steel wheelchairs is low, they are heavy in quality and poor in corrosion resistance.

Aluminum alloy wheelchairs are moderately priced and have good corrosion resistance, but are heavy and inconvenient to carry.

Magnesium alloy wheelchairs are moderate in price, high in strength, light in weight, and not easy to corrode.

Carbon fiber wheelchairs are expensive, but have good load-bearing capacity, but weak impact resistance.
