Extrusion produces continuous brass profiles in virtually any cross-sectional shape. Understanding extrusion capabilities helps in design optimization.
Extrusion Process
Hot Extrusion
Brass is heated and forced through a die under high pressure:
- Complex cross-sections possible
- Excellent surface finish
- Good mechanical properties
- High production rates
Cold Extrusion
Room temperature forming for specific shapes:
- Better tolerances
- Improved strength
- Limited to simpler shapes
Profile Types
- Solid: Bars, rods, tubes
- Hollow: Tubes with various cross-sections
- Semi-hollow: Partial internal cavities
- Custom: Application-specific shapes
Common Applications
- Architectural trim
- Heat sinks
- Marine hardware
- Industrial profiles
- Automotive sections
Design Considerations
- Wall thickness uniformity
- Corner radii
- Die life considerations
- Secondary operations needed
