What is the material of rail fastening system?

Metallic Materials

Steel: Steel is a strong and durable material commonly used in rail fastening systems. It is capable of withstanding the high loads and vibrations experienced by railway tracks. Steel clips, spikes, and other fasteners are often made from this material.

Aluminum Alloy: Although less common than steel, aluminum alloy can also be used in some rail fastening components due to its lightweight and corrosion-resistant properties. However, its strength may be less than that of steel, so it is typically used in applications where weight reduction is a priority.

Non-Metallic Materials

Rubber: Rubber is often used in rail pads, which are placed between the rail and the sleeper to provide cushioning and reduce vibrations. Rubber pads can help improve the riding quality of trains and reduce wear and tear on the track components.

Plastic: Some plastic materials, such as nylon or polyurethane, may be used in rail fastening components due to their corrosion resistance and ability to withstand a wide range of temperatures. However, their strength and durability may be limited compared to metallic materials.

Composite Materials

Composite materials, which are made by combining two or more different materials (such as fiberglass and resin), are also used in rail fastening systems. These materials offer a combination of strength, stiffness, and corrosion resistance. Composite rail clips and other fasteners can be designed to meet specific performance requirements and can be tailored to fit different types of railway tracks.
