Be-Cu alloy
Be-Cu alloy
(OP)
Hello all
I am currently using Be-cu alloy for a connector. I am planning to change this material to an alternative.
Be-Cu - C17300 UNS
This connector is used in coaxial cable where a male pin is inserted between the crimped fingers in a female pin. The crimped fingers should last the insertion/widhrawal force cycle. The insertion/widhrawal force is approx. 0.80lbs
Thanks

Cost reduction?
Reliability?
Conductivity?
Greater contact force?
Other?

RE: Be-Cu alloy
Any inputs on alternative materials???
RE: Be-Cu alloy
brass (ASTM B16) or
303 or 303Se stainless steel (ASTM A582)
These may require a surface plating as with most electrical connectors.
RE: Be-Cu alloy
Thanks for your inputs. I will give some more specific details what I am looking for.
The current material Be-cu alloy (C17300 UNS):
We buy as rods and machine them to thickness approx (nominal) 0.5mm
Then we heat treat at 600F for 3 hours to achieve harness level of 38-45 Rc; T.S 175-225Ksi.
Any input on an alternative material?
Will the S.S 303/303se and Brass B16 suit?
Thanks in adavance for your suggestions
RE: Be-Cu alloy
The CrCu alloys are common, and there are a bunch of others.
Most BeCu connectors are stamped or punched, not machined. That way people don't have to worry about the health effects of the Be.

RE: Be-Cu alloy
Thanks. Any specific grade in CrCu alloys?
RE: Be-Cu alloy
The alternative material choices of brass or stainless were based on information from a source that I know who deals with coax/cable RF connectors.
RE: Be-Cu alloy
I have info on an alternate material that performs very much like the C17300. It is marketed for your application.
I could refer you to the manufacturer
