The material requirements of electric linear actuators mainly include the following aspects:
Stainless steel: Stainless steel has good corrosion resistance and wear resistance, and is suitable for occasions such as food processing machinery that require high hygiene standards. Different types of stainless steel (such as 304, 316, etc.) are suitable for different working environments. For example, some types are more suitable for high humidity or chemical corrosion environments.
Aluminum alloy: Aluminum alloy is light and strong, has good thermal conductivity and processing performance, and is often used in weight-sensitive applications, such as portable devices such as mobile robots and drones.
Carbon steel: Carbon steel has low cost, good hardness and wear resistance, and is suitable for use under general working conditions. After surface treatment, its anti-corrosion ability can be improved, and it is widely used in ordinary mechanical equipment.
Engineering plastics: For occasions with special requirements for low noise or insulation performance, specially formulated engineering plastics are a good choice. Such materials are usually lightweight and can provide sufficient rigidity to meet basic functional requirements.
Composite materials: In recent years, composite materials made by combining metal with other non-metallic materials have also begun to be used in the production of electric push rods. These composite materials can further improve certain performance indicators while maintaining the original advantages.
Resin polymer materials: This material has insulation ability and good toughness. It is often used in precision instruments and equipment. It can not only ensure the lifting accuracy, but also effectively reduce the test error caused by electric porcelain.
Carbon fiber: Carbon fiber materials are light and strong. They are suitable for small push rods, such as electric home and household equipment. They are moderately priced and have a long life.
