CNC Beryllium Copper Machining at AOOM

Beryllium copper is a specialty material. It has exceptional strength, thermal conductivity, and electrical properties. But it's difficult to machine. The alloy work-hardens fast, which catches inexperienced shops off guard.

We've developed a dedicated process for beryllium copper at AOOM. Our machinists know the feed rates and speeds that prevent work hardening. We use sharp carbide tooling and replace inserts on a tight schedule.

Our Process for Beryllium Copper

We start with proper fixturing. Beryllium copper can be springy in thin sections, so we use custom fixturing to dampen vibration. Tool selection is critical: we run specialized geometries that shear the material cleanly.

Cutting parameters are controlled tightly. We keep chip loads consistent and avoid dwell marks. In-process quality checks happen at every stage. Final inspection uses CMM for dimensional accuracy.

We have dedicated machining centers for non-ferrous materials. This prevents cross-contamination from ferrous shop dust.

Parts We Make and Industries We Serve

Beryllium copper components from our shop include electrical connectors, aerospace bearings and bushings, mold components, high-performance springs, and oil and gas exploration parts.

One aerospace client needed beryllium copper bushings with a tight ID tolerance. The material's work-hardening tendency made it a challenge. We hit the tolerance on the first article and maintained it through the full production run.

This is not a material for every shop. We've invested the time to get it right.
