Drawn ordinary brass rod
Drawn brass rod is a copper alloy primarily composed of copper and zinc. Formed through a drawing process, it is one of the most widely used copper alloys in industry. The addition of zinc significantly increases the strength and hardness of brass compared to pure copper, while maintaining copper’s excellent ductility and workability, making it easy to process through cutting, stamping, and drawing. Brass rod has a beautiful golden color and a decorative quality, making it suitable for applications requiring a high level of aesthetic appeal. The properties of brass rod vary depending on its zinc content. Lower zinc contents result in greater plasticity, while higher zinc contents improve strength and hardness, but reduce plasticity.
The production process for drawing ordinary brass rods is relatively mature, and mainly includes smelting, casting, drawing and annealing. During smelting, copper and zinc are placed in a furnace in a certain proportion and heated to melt. In order to remove impurities and gases in the melt, some refining agents are usually added. After smelting is completed, the melt is cast into ingots of a certain size. The quality of the ingot directly affects the effect of subsequent drawing processing. During the drawing process, the ingot is stretched through the die, so that the diameter of the rod is gradually reduced to the required size. At the same time, the structure of the material is refined and the mechanical properties are improved. During the drawing process, if the deformation is too large, it will cause work hardening of the material. Therefore, intermediate annealing treatment is required to restore the plasticity of the material and ensure that the drawing process can continue.
Drawn brass rod has a wide range of applications in both daily life and industrial production. In the electrical industry, it’s often used to make connectors, terminals, and other conductive components for wires and cables, leveraging its excellent conductivity to facilitate current transmission. In plumbing, brass rod is processed into various valves, fittings, and faucets. Its corrosion resistance and ease of processing meet the requirements of plumbing systems. Brass rod is also frequently used as a raw material in the manufacture of everyday items such as zippers, keys, and decorative items, ensuring both performance and aesthetic appeal.
Compared to other copper alloys, drawn ordinary brass rods offer the advantage of lower costs, making them more competitive in applications where performance requirements are less stringent. While their corrosion resistance and strength are inferior to those of specialty copper alloys like silicon bronze and aluminum bronze, their performance is sufficient for use in many common industrial scenarios. Furthermore, ordinary brass rods have a high recycling rate, meeting the requirements of environmental protection and sustainable development—an advantage that is particularly important in today’s increasingly resource-constrained world. Through proper design and application, drawn ordinary brass rods can effectively reduce production costs while ensuring product quality.
With the development of industry and advancements in technology, the applications of drawn brass rods continue to expand. Emerging sectors, such as electronic equipment manufacturing and medical devices, place higher demands on the precision and performance of brass rods. Manufacturers are adapting these demands by improving their processes to produce high-precision, high-performance brass rods. At the same time, market demand for differentiated brass rods is also increasing, with the emergence of numerous products with specialized specifications and performance characteristics, such as free-cutting brass rods and high-strength brass rods. It is foreseeable that drawn brass rods, with their excellent overall performance and cost advantages, will continue to maintain their important position in the future market.
