Magnesium alloy car wheel hub
The characteristic of Magnesium alloy wheels
Magnesium alloy car wheel hubs have the characteristic of absorbing vibrations, and their high dimensional accuracy and good balance achieved through CNC machining make cars stable and comfortable. Magnesium alloy car wheel hub can reduce the vibrations of car engines, suspension systems, and transmissions, thereby improving their lifespan. Magnesium is one-third lighter than aluminum, and its damping and shock-absorbing properties are 25 times greater than that of aluminum. By replacing aluminum wheels with magnesium alloy wheels, not only is fuel efficiency improved, but it also becomes an important way to achieve car lightweighting.
The heat dissipation coefficient of magnesium alloy car wheel hub is two to three times that of regular wheels. It effectively dissipates the heat generated by the braking system into the air, even during continuous braking on long-distance drives, ensuring that the brake system maintains a lower temperature and guarantees driving safety. Magnesium alloy car wheel hubs can achieve personalized and simplified appearances, which align with modern people's fashion concepts.
Refined Microstructure of AZ80 New Weakly Textured Magnesium Alloy
Overcoming the challenge of refining the eutectic phase in the AZ80 high-alloy system has been a significant breakthrough for magnesium alloy wheels. Through technological advancements, the refinement of the AZ80 eutectic phase has been achieved, resulting in the development of a new weakly textured magnesium alloy.
This advancement has addressed the difficulties in processing, low yield rates, low fatigue strength, and poor corrosion resistance typically associated with traditional magnesium alloy wheel materials, specifically AZ80. The new magnesium alloy wheel materials now demonstrate improved processing capabilities, higher yield rates, enhanced fatigue strength, and better corrosion resistance.
As a result, the current yield rates and fatigue strength of these new magnesium alloy wheel materials are comparable to those of aluminum alloys. This breakthrough has eliminated major obstacles previously faced by magnesium alloy wheels in their competition with aluminum alloy wheels.
As a consequence, there is a significant anticipation of tremendous demand for the company's new magnesium alloy wheel materials in the market.
Manufacturing process：
Magnesium alloy car wheel hubs with a eutectic phase refined microstructure of AZ80 new weakly textured magnesium alloy,Here's the process:
Alloy Composition: Determine the composition of the AZ80 alloy. AZ80 is a commonly used magnesium alloy that contains 8-9% aluminum (A) and 0.4-0.7% zinc (Z). Other elements, such as rare earth metals, may be added to enhance certain properties.
Melting and Casting: Melting and casting the alloy can be done using various methods, such as die casting or permanent mold casting. In this step, the raw materials, including magnesium, aluminum, zinc, and any additional elements, are melted together in a controlled environment.
Grain Refinement: To achieve a refined microstructure, grain refinement techniques can be applied. Grain refiners, such as titanium or zirconium, are added to the molten alloy to promote the formation of fine grains during solidification. This helps to improve the mechanical properties of the final product.
Casting Process Optimization: Optimize the casting process parameters, such as temperature, cooling rate, and mold design, to ensure proper filling and solidification of the wheel hub. This step may involve conducting trials and adjusting the process parameters to achieve the desired microstructure.
Heat Treatment: After casting, the wheel hubs may undergo a heat treatment process to further enhance their properties. This can involve solution treatment and aging processes, which help to strengthen the alloy and improve its mechanical properties.
Machining and Finishing: Once the wheel hubs have been cast and heat-treated, they need to be machined to their final shape and dimensions. This can be done using CNC (Computer Numerical Control) machining processes. After machining, the hubs may undergo surface finishing treatments, such as polishing or coating, to improve their appearance and corrosion resistance.
Quality Control: Throughout the manufacturing process, it is crucial to conduct rigorous quality control checks to ensure that the wheel hubs meet the required specifications. This can involve various inspections, such as dimensional checks, mechanical testing, and non-destructive testing techniques.
Price: A single magnesium alloy car wheel hub range anywhere from $300 to $800 or more
