CuBe2 Beryllium Copper

Beryllium copper (CuBe2). After heat treatment, it reaches the highest strength of all copper alloys; it is non-sparking and non-magnetic.

Grade and sizes

Beryllium copper · CW101C

CuBe2

A copper alloy with about 2 % beryllium, hardened by solution annealing and age hardening. In the aged condition its tensile strength exceeds 1100 MPa, giving it the highest strength of all copper alloys together with excellent spring properties and fatigue strength. It is non-sparking and non-magnetic, and its thermal conductivity is several times that of tool steel. In solid form it presents no special health risk; operations that generate dust or fume, such as grinding, welding and dry cutting, require local extraction and ventilation.

Frequently asked questions

What precautions should be taken when processing beryllium copper?

Beryllium copper in solid form, and finished parts made from it, present no special health risk. The risk comes from breathing fine dust, mist or fume produced during processing. Conventional machining such as turning, milling and drilling is low-risk when carried out with flood coolant on well-maintained machines. Grinding, polishing, welding, EDM and very high-speed machining require dust and fume extraction, and swarf and coolant residues should be cleaned up before they dry. See the producer's safety data sheet for details.

What are the designations for CuBe2?

CuBe2: Beryllium copper, EN CW101C, DIN 2.1247, UNS C17200. Any of these designations can be used in your enquiry; we will match the correct material.

Why can the invoiced weight differ from the calculated weight?

The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.

What information should I send for a quote?

We only need the size (diameter × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
