Heatsink Extruded-FAQ's
What alloys are commonly used for extruded heat sinks?
6061 and 6063 aluminum alloys are most popular due to their balance of strength, thermal conductivity, and extrusion capability.
Can you create custom fin shapes?
Yes, we design and manufacture custom extrusion dies for straight, radial, or complex fin geometries.
What surface treatments are available?
Options include anodizing, powder coating, chromate conversion, or painting for corrosion resistance and appearance.
How are the heat sinks processed after extrusion?
Profiles are cut to length and can undergo CNC machining, drilling, tapping, or slotting as needed.
Are extruded heat sinks cost-effective?
Yes, extrusion offers a more affordable and scalable process compared to skiving or forging.
What sizes are available?
Profiles can range from small PCB-level sinks to large industrial extrusions, tailored per requirements.
Do you provide prototypes?
Yes, we support rapid prototyping and low-volume trial runs before mass production.
How do you ensure quality?
Each batch undergoes dimensional inspection, thermal performance testing, and surface finish verification.
