However it is recommended to use gloves and a mask when working with this material. The problem is that Beryllium is a known cancer agent when microscopic particles or fumes are ingested into the lungs. Beryllium can cause irritation to the eyes, lungs and skin. BeCu is used in many electronic and industrial applications due to it's superior properties. Several applications have moved from BeCu to Cu-Ni-Sn to reduce any cancer risks.

I completely concur, I came into RF engineering when this was being realized and worked to redesign several BeCu connectors/contacts to use different materials.

Phospor Bronze is also an alternative to BeCu, however it cannot be spring tempered like BeCu.
