Hot Extrusion: Reliable Hot Extrusion from Huaxiao
Hot Extrusion pushes heated, softened metal through a die to form long, uniform profiles with excellent grain flow—the workhorse for aluminum and steel sections.
How Hot Extrusion Works
The billet is heated above recrystallization, then forced through a shaped die by a hydraulic ram; the hot metal flows out as a continuous profile that is cooled and cut to length.
Hot vs. Cold Extrusion
Hot extrusion needs lower force and handles larger, complex shapes; cold extrusion gives tighter tolerances and a harder surface. Choose hot for big structural profiles.
Materials
- Aluminum alloys—light, corrosion-resistant sections
- Steel—structural and automotive profiles
- Copper and brass—conductive and decorative bars
Industries
Construction, automotive, rail, and electrical busbar all rely on hot-extruded sections.
How to Spec Your Hot Extrusion Job
- State alloy and temper (6061-T6, 6063).
- Define cross-section and critical tolerances.
- Note wall thickness and any hollow needs.
- Set surface finish and straightness.
- Provide length and quantity.
FAQ
What alloys work best?
Aluminum, copper, brass, and many steels extrude well hot.
How precise is it?
Good for structural profiles; add CNC for tight tolerances.
