Chapter 1 Overview of Tungsten Alloy Rivet Tops
1.1 Definition of Tungsten Alloy Rivet Top Rod
Tungsten alloy rivet mandrels are alloy products with tungsten as the main component. They are typically manufactured using powder metallurgy and machined into specific rod- shaped tools, primarily used for support and shaping during the riveting process. These mandrels are placed at the rivet tail during installation, acting as a reverse support to withstand hammering or pressure, allowing the rivet head to deform smoothly and form a secure connection. Tungsten alloy is chosen for its high density and hardness, enabling it to maintain shape stability under repeated impacts while possessing a certain degree of toughness to prevent brittle fracture. The diameter and length of the mandrel are designed according to the rivet specifications, and its surface is often precision ground to ensure a good fit with the rivet tail.
Tungsten alloy mandrels commonly use tungsten -nickel-iron or tungsten-nickel-copper alloys. The binder phase provides the necessary plasticity, making the mandrel less prone to cracking during processing and use. The preparation process includes powder mixing, pressing, sintering, and thermomechanical processing, with final heat treatment to adjust the microstructure. The working surface of the mandrel needs to be smooth and flat to reduce friction and damage during rivet deformation. The emergence of tungsten alloy mandrels has solved the problem of insufficient durability of traditional steel mandrels in high-strength rivet applications, especially in applications requiring multiple uses, where their lifespan is more stable.
From a functional perspective, tungsten alloy rivet setters not only provide mechanical support but also, through their high density, help concentrate energy transmission, resulting in more uniform rivet deformation. The setter’s end face shape is diverse, such as flat, concave , or convex , to accommodate different rivet types. In use, the setter is fixed to a pneumatic or manual riveting gun, and the operator controls the force to achieve the connection. Maintenance of tungsten alloy setters is relatively simple; regular inspection of surface wear and polishing are sufficient. In conclusion, as an important component of riveting tools, tungsten alloy rivet setters , with their material advantages, improve the efficiency and quality of the connection process and are gradually gaining recognition in the industrial assembly field.
1.1.1 Structural features of tungsten alloy rivet top bars
Tungsten alloy rivet mandrels are mainly reflected in their rod-shaped shape and internal two-phase microstructure. The external design emphasizes functional adaptability, while the internal microstructure determines durability. The mandrel is cylindrical in shape, with one end serving as the working surface for direct contact with the rivet tail, and the other end as a gripping or fixing end for easy installation in riveting equipment. The working surface is typically flat or has shallow grooves to better accommodate rivet tail deformation, and the smooth sides reduce operating resistance. The length and diameter ratio is matched to the rivet size to ensure stable support without interfering with surrounding components.
The internal structure exhibits typical tungsten alloy dual-phase characteristics, with tungsten particles forming a continuous skeleton as the hard phase, and binder phases such as nickel-iron or nickel-copper filling the gaps, providing connectivity and toughness. This microstructure is formed through a sintering process, with nearly spherical tungsten particles and a uniformly distributed binder phase to prevent stress concentration. After hot working, the microstructure displays a fibrous texture, aligned axially to enhance longitudinal strength. The surface is finely ground, resulting in low roughness and reduced rivet adhesion.
