Extruded brass combines exceptional durability, conductivity, and aesthetic appeal, making it an ideal material for countless industrial and commercial applications. This versatile manufacturing process creates precise, uniform brass profiles with superior mechanical properties compared to cast alternatives. At MAIKONG, we specialize in custom extruded brass components that deliver exceptional performance across plumbing systems, electrical components, and architectural elements.
What is Extruded Brass and How is it Manufactured?
Extruded brass is created through a metal working process where brass alloy is heated and forced through a die to create a specific cross-sectional profile. This manufacturing technique produces components with consistent dimensions, excellent surface finish, and enhanced mechanical properties compared to casting or other forming methods.
The Extruded Brass Manufacturing Process
The extrusion process begins with selecting the appropriate brass alloy based on the desired properties and application requirements. The brass is then heated to increase ductility before being forced through a precision-engineered die under high pressure. This creates a continuous length of material with a uniform cross-section that can be cut to the required dimensions.
At MAIKONG, our advanced extrusion equipment allows us to produce complex profiles with tight tolerances, ensuring consistent quality across production runs. Our process engineers optimize each parameter to achieve the ideal balance of mechanical properties and surface finish.
