Machining Copper Heat Sinks: Thin Fins, Sharp Tools, and a Material That Wants to Smear
Why copper C1100 heat sinks need razor-sharp tools, optimized feeds, and careful burr control — and how to keep fragile fins from deflecting on a 20,0
Aerospace, automotive, robotics, electronics and industrial equipment — each with its own tolerance culture, documentation requirements and failure tolerance.

Thin-wall brackets, housings and structural-style parts milled in aluminum 6061-T6 with drawing-defined tolerance.
