What are Brass Extrusion Rods?
What are Brass Extrusion Rods?
Brass extrusion rods are cylindrical metal bars manufactured through a specialised hot extrusion process where heated brass billets are forced through precision dies under extreme pressure. This manufacturing method produces rods with superior dimensional accuracy, enhanced mechanical properties, and consistent metallurgical structure.
Key Benefits & Advantages
Key Benefits & Advantages
Superior Machinability: Excellent cutting characteristics for high-speed manufacturing
Corrosion Resistance: Natural resistance to environmental degradation

Cost Effectiveness: Efficient production method, reducing material waste
Why Choose Extrusion Over Other Methods?
Why Choose Extrusion Over Other Methods?
Brass extrusion offers significant advantages over alternative manufacturing methods, including superior material flow, elimination of internal defects, better surface finish, and the ability to produce complex cross-sectional profiles with consistent mechanical properties throughout the length.
Manufacturing Process
Manufacturing Process
The brass extrusion process involves several critical stages, each requiring precise control of temperature, pressure, and timing to ensure optimal rod quality and dimensional accuracy.
Billet Preparation
Billet Preparation
Solid brass billet is prepared and surface cleaned to remove oxidation. Billet size must match extrusion press capacity.
Room Temperature
Heating
Heating
Billet heated to the working temperature range. Lubricant applied before extrusion.
900°F - 1,300°F (480°C - 700°C)
Extrusion
Extrusion
Heated billet is pushed through the die under high pressure. Die controls the final shape and dimensions.
Working Temperature Maintained
Cooling
Cooling
Extruded rod cooled with air or water. Straightening is performed during cooling.
Controlled Cooling Rate
Finishing
Finishing
Cut to length, surface treatment if required. Additional machining, drilling, or polishing as needed.
Room Temperature
Types of Extrusion Methods
Types of Extrusion Methods
Direct Extrusion: The most common method, where billet and ram move in the same direction through a stationary die.
Indirect Extrusion: The Die moves toward the stationary billet, reducing friction and required force.
Impact Extrusion: High-speed process using impact force for small diameter rods.
Hydrostatic Extrusion: Uses a fluid pressure medium for uniform pressure distribution.
