Scratch-resistant wheelchair aluminum alloy hubWheelchair Aluminum Alloy Hubs: Safeguarding Every Rotation with CareEvery smooth roll of a wheelchair relies on the quiet support of its hub, a core component connecting the wheels to the frame. Aluminum alloy hubs, with their lightweight and high-strength properties, have become an ideal choice for many wheelchairs. However, scratches on the aluminum surface not only mar its appearance but may also lead to oxidation and corrosion, affecting its service life. Thus, "scratch prevention" becomes crucial in preserving the hub's performance.Preventing scratches is not just a superficial effort but a systematic protection from material selection to craftsmanship. High-quality wheelchair aluminum alloy hubs use high-purity aluminum, enhanced through special heat treatment to increase surface hardness, like wearing an invisible armor. Anodizing is a common "protective technique" here—electrochemical reactions form a dense oxide film on the metal…
