Alloys of aluminum wire for electric traction
In electric traction applications, commonly used aluminum alloys are aluminum magnesium alloy (Al Mg alloy) and aluminum manganese alloy (Al Mn alloy). These two alloys have good conductivity and mechanical strength, making them suitable for use in power transmission and traction systems.
Aluminum magnesium alloy has good strength and corrosion resistance, as well as high conductivity, making it a common choice in electric traction applications. The main components of this alloy are aluminum and a small amount of magnesium. Adding magnesium can improve the strength and hardness of aluminum while maintaining good conductivity. Represents alloy 5052.
Aluminum manganese alloy is another common alloy for electric traction applications. Its main components are aluminum and manganese. Aluminum manganese alloy has good conductivity and high mechanical strength. Compared to aluminum magnesium alloys, aluminum manganese alloys have higher strength, but their performance in corrosive environments may be slightly worse. Represents alloy 3003.
AA6101 (Aluminum Magnesium Silicon Alloy): this is an aluminum magnesium silicon alloy suitable for traction and power wires. It has good conductivity and strength, as well as good corrosion resistance.
AA6201 (Aluminum Magnesium Silicon Alloy): similar to AA6101, AA6201 is also an aluminum magnesium silicon alloy commonly used for traction wires and wires. It has high strength and good conductivity.
These aluminum alloy wire for electric traction widely used in electric traction due to their low density, good conductivity, mechanical strength, and lower cost compared to other metals such as copper.
Advantages of Chalco aluminum wires for electric traction
Lightweight and highly conductive: aluminum is a lightweight metal with a density of approximately one-third that of copper. In contrast, using aluminum wire can reduce the weight of the cable and reduce the load on the traction system. Although aluminum has a lower conductivity than copper, its lightweight properties can provide higher conductivity.
Good conductivity: although aluminum has a lower conductivity than copper, it still has good conductivity. Electric traction wire can effectively transmit electrical energy and reduce energy loss during the power transmission process.
Corrosion resistance: aluminum wire for electric traction has good corrosion resistance and can resist the corrosion of atmospheric environment and some chemical media. This makes aluminum wire more reliable for outdoor and humid environments.
Cost effectiveness: compared to copper wire, Aluminum wire for electric traction has lower manufacturing costs. Aluminum resources are relatively abundant and prices are relatively low, so using aluminum wires can reduce the construction and operation costs of traction systems.
Plasticity and workability: aluminum wire for electric traction has good plasticity and workability, and can be manufactured into various shapes and sizes of wire to meet different traction system requirements.
Environmental sustainability: the use of Aluminum wire for electric traction can reduce resource consumption and reduce its impact on the environment. Aluminum is a recyclable metal, and recycling aluminum wire can help reduce waste generation and energy consumption.
Precautions for purchasing aluminum wires for electric traction
