Currently, magnesium alloy wheelchairs are gradually transitioning from emerging technology to large-scale application. While this material offers numerous advantages due to its unique properties, it also faces challenges in manufacturing costs and production processes. The following is a detailed analysis:

Major Advantages of Magnesium Alloy Wheelchairs

 

 

The competitive advantages of magnesium alloy wheelchairs are concentrated in the following areas:

Significant Weight Reduction: Magnesium alloy has a density approximately two-thirds that of aluminum alloy and one-quarter that of steel, achieving an extremely lightweight wheelchair structure.

Excellent Durability: Due to its high specific strength, magnesium alloy reduces weight while maintaining the structural integrity and load-bearing capacity of the frame, exhibiting excellent deformation resistance.

Excellent Shock Absorption: Magnesium alloy possesses high damping properties, effectively buffering vibrations and shocks during driving, particularly on uneven roads, contributing to improved ride comfort.

Electromagnetic Shielding: Magnesium alloy provides effective shielding against electromagnetic interference.

Heat Dissipation and Formability: Magnesium alloy has high heat dissipation efficiency and good processability.

Production Process and Current Difficulties

The manufacturing and promotion of magnesium alloy wheelchairs still face the following challenges:

Complex profile processing: Magnesium alloys are prone to bending and deformation during extrusion and straightening. Their low plasticity at room temperature makes them prone to defects such as wrinkling, warping, and springback deviation when manufacturing complex structures with thin walls and multiple ribs. These process challenges result in low product yields, indirectly driving up overall costs.

High production costs: High raw material prices, complex processing steps, and high scrap rates during production all contribute to the current manufacturing cost of magnesium alloy wheelchairs exceeding that of conventional materials.

Overall, high production costs and immature process technology are the main obstacles to the large-scale market adoption of magnesium alloy wheelchairs. However, with continued improvements in manufacturing technology, the gradual improvement of supporting industrial infrastructure, and growing market demand for lightweight wheelchairs, the overall cost of magnesium alloy wheelchairs is expected to gradually decrease, further expanding their application potential.
