Machining Beryllium Copper C17200

Machinability is rated good — a well-behaved material to machine with correctly chosen tooling and parameters. Brass CZ121 and CZ131 are among the most economical materials to machine — their outstanding chip-breaking behaviour allows high speeds and excellent surface finish. Beryllium copper must be machined with appropriate respiratory controls in place.

Our standard achievable tolerance on Beryllium Copper C17200 is ±0.010mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Non-sparking tools, precision springs, aerospace connectors, semiconductor tooling.
