In the field of robotics, it is crucial to find parts that are both lightweight and strong.Aluminum as a transformative material, effectively cope with this challenge.Aluminum's lower density, about a third of that of steel, makes it ideal for reducing the weight of robot parts.For mobile robots, this can reduce energy consumption, extend battery life, and increase operating range. In addition, aluminium has a relatively high strength-to-weight ratio. Its strength can be further enhanced through alloy formulas and heat treatment processes.Aluminum alloys such as 6061 and 7075 have high tensile strength and good fatigue resistance, allowing the robot to withstand the stress generated during operation.In addition, the natural formation on the surface of aluminum oxide layer has corrosion resistance, to ensure its durability in various harsh environment, reducing maintenance requirements.
Aluminum has good plasticity and ductility, is easy to be processed into various shapes.It can be cast, forged, extruded and machined to create complex and customised robot parts.Extrusion aluminum can be used to build a robot framework, to provide a lightweight and solid structures.Precise features can then be added by machining to allow the installation of additional components. This easy-to-process feature helps to develop efficient and reliable robots.
In robotic arms, its light weight means less inertia, so movements are smoother, while still being strong enough to carry loads without bending. Its resistance to corrosion makes it ideal for factories and harsh settings. For mobile robots, aluminum chassis strike a nice balance between strength and weight, helping them squeeze through tight spaces. And because it’s so easy to shape, integrating sensors, motors, and batteries becomes way simpler. Even in end-effectors (like grippers), using aluminum keeps things light without sacrificing grip strength—boosting both performance and energy efficiency. As robots keep evolving, aluminum will only become more important in making them smarter, lighter, and more capable.
