In the current society, as an emerging slow transportation tool, electric wheelchairs have been gradually recognized by many elderly and disabled persons. With the advancement of society and the development of technology, the types and configurations of electric wheelchairs have become More and more, there are many kinds of materials in terms of materials, such as carbon steel, aluminum alloy, magnesium alloy, and relatively high-grade carbon fiber, aviation titanium aluminum alloy, etc., so we face so many different materials How to choose a cost-effective electric wheelchair? What kind of electric wheelchair is better?
The first thing we need to know is that each group and user’s own situation and use environment are different, which also leads to the differentiation of the purchased products. In this differentiated demand, we will give you the following aspects: Some suggestions and instructions.
Common materials are mainly divided into carbon steel, aluminum alloy, aviation titanium aluminum alloy and magnesium alloy. We will not talk about carbon fiber for the time being (high price and less application);
1. Carbon steel material:
Carbon steel frames are mainly used for heavy-duty wheelchairs and some brands produced in small factories. Heavy-duty wheelchairs use steel frames to enhance the rigidity and driving stability of the body. For example, the frames of many large trucks are steel frames. The same reason that small cars can use aluminum is the same. Wheelchairs produced in small factories use steel frames because the processing and welding process requirements are relatively low, and the cost is relatively low.
2. Aluminum alloy & titanium aluminum alloy
Aluminum alloy and titanium-aluminum alloy, the frames of these two materials occupy most of the market for electric wheelchairs. They are two different types of aluminum materials, 7001 and 7003, that is, aluminum materials are added with other different mixed materials. Their common characteristics are low density and high strength, good plastic resistance and corrosion resistance. To put it intuitively, they are light, strong and easy to process. Titanium aluminum alloy has higher strength and corrosion resistance. It is widely used in the aerospace field, so it is also called aviation titanium aluminum alloy. Because the melting point of titanium is very high, it can reach 1942 degrees, this melting point is more than 900 degrees higher than gold, so its processing technology and welding are naturally very difficult, and ordinary small processing plants cannot make it, so aviation titanium aluminum Alloy wheelchairs sell for higher prices. In the purchase option, the former is suitable for users who are not frequently used, the road surface and the driving environment are relatively good, and users who use frequently, often need to be transported, and who often drive on potholes and bumpy roads can choose titanium aluminum alloy wheelchairs. .
