About Aluminum Alloy Gear
One-stop Custom Gear Factory
Sango Automation has been deeply involved in the field of gear manufacturing for more than ten years and now has rich experience in customization. We do not produce standard gears, but devote all our energy to the process of customizing gears for our customers.
At Sango, you can customize gear products in various materials, such as aluminum alloy gear, cast iron gear, nylon gear, etc.
Product Peculiarity
Lightweight
The density of aluminum alloy gear is about 1/3 of that of steel gears, so the overall weight and moment of inertia of the transmission system produced with aluminum gears are lower than those with steel gears, making them used in scenarios that require high-speed start-stop and quick response (robots, automation equipment, etc.).
Corrosion resistance
Aluminum alloy will form a dense oxide film on the surface of the material under natural conditions, this oxide film has a certain ability to resist atmospheric and chemical media corrosion, if the customer's working conditions require higher corrosion resistance, it can also be achieved through anodizing and other surface treatments.
Thermal conductivity
Aluminum alloy gears have good thermal conductivity, which can effectively conduct and dissipate the heat generated during the gear meshing process, helping to reduce the operating temperature of the entire transmission system.
Ease of processing
Aluminum alloy has excellent cutting performance, low cutting force, and slow tool wear. This makes it easy to efficiently manufacture high-precision gears with complex shapes through CNC and other processes, which has a significant cost advantage when producing large quantities.
Material Selection
The aluminum material chosen for aluminum alloy gear directly affects the performance of the gear produced. The aluminum alloy used to make gears is not ordinary aluminum, but forged aluminum alloy with high strength, the most commonly used are aluminum alloy 2011, aluminum alloy 6061, and aluminum alloy 7075.
