Nice to meet you.
I would like to ask you about making a compression spring. When making a compression spring with the following specifications using beryllium copper wire as a spring material, how should the “quenching temperature” be set? A roughly estimated number is okay too.
The specification is as follows:
Compression spring
Spring material (beryllium copper)
Diameter: 0.10 mm
Purity: Unknown
Diameter: 0.60 mm
Freelength: 2.00 cm
Spring constant 0.1 N/mm
By the way, this spring is planned to be used as a mechanical component of a system.
Thank you for writing to us, Koala!
Rather than being quenched, the Beryllium copper wire is normally age hardened. Please note that the age hardening treatment temperature is 315 ± 5°C and the time varies depending on the type of material.
For O type, it is 180 minutes, 120 minutes for 1/4H type, and 60 minutes for 3/4H type according to JIS H3270.
