Brass extrusion stands as one of the most versatile and cost-effective manufacturing processes for creating precision components with complex profiles. This comprehensive guide explores why brass extrusion should be your material and process of choice for engineering applications that demand reliability, precision, and aesthetic appeal. MAIKONG brings decades of expertise in brass extrusion to US engineering firms seeking high-quality, cost-effective manufacturing solutions with the perfect balance of performance and value.
Understanding Brass Extrusion: The Manufacturing Process
The brass extrusion process at MAIKONG’s state-of-the-art facility
Brass extrusion is a specialized metal working process where brass alloy is heated to a specific temperature and then forced through a die to create a fixed cross-sectional profile. This versatile manufacturing technique allows for the creation of complex shapes with consistent dimensions throughout the length of the extruded piece.
The process begins with selecting the appropriate brass alloy based on the desired mechanical properties and application requirements. The brass is then heated to its recrystallization temperature, where it becomes malleable without fully melting. Using powerful hydraulic presses, the material is forced through precision-engineered dies to form the desired shape.
Types of Brass Extrusion Processes
Direct Extrusion
In direct brass extrusion, the billet, ram, and punch move in the same direction. This method is ideal for creating simple shapes with excellent surface finishes and is highly efficient for large production volumes.
Indirect Extrusion
Indirect extrusion involves the punch and billet moving in opposite directions. This technique requires less force than direct extrusion and produces minimal friction, making it suitable for certain specialized applications.

Design Considerations for Brass Extrusion Projects
Successful brass extrusion projects begin with thoughtful design that considers both the capabilities of the manufacturing process and the requirements of the end application. Our engineering team at MAIKONG works closely with clients to optimize designs for manufacturability while meeting performance specifications.
Key Design Factors for Brass Extrusion
Wall Thickness
Maintaining uniform wall thickness throughout the profile helps ensure consistent material flow during extrusion. Minimum recommended wall thickness is typically 0.8mm for most brass alloys.
Corner Radii
Sharp corners should be avoided in brass extrusion designs. Internal corners should have a minimum radius of 0.5mm to prevent stress concentration and die failure.
Symmetry
Symmetrical profiles generally extrude more consistently and with better dimensional accuracy than asymmetrical designs. When asymmetry is necessary, additional considerations may be required.
Tolerances and Surface Finish
Brass extrusion can achieve excellent dimensional accuracy and surface finish, but understanding the practical limitations helps set realistic expectations for your project.
