Machinable Brass for Spring?

Machinable Brass for Spring?

Machinable Brass for Spring?

(OP)
Hi All,

I'm designing an electrical connector housing that is to be machined from brass. I need to design in a ramping bayonette-style twist lock into this housing...like what you would find on a typical BNC cable connector. This particular design requires that a piece of the brass flex like a spring a little bit when connecting the cable.

I'm trying to source some brass rod to try a couple design experiments. I saw that 260 Brass is used for springs, but can only find is in wire sizes. Any recommendations for a machinable brass that can withstand bending & fatigue a little more than standard 360 brass?

RE: Machinable Brass for Spring?

If you look real close at a BNC connector, you'll find that the spring action is not in the ramped part, nor is it in the pin part; it's in a wave spring that you won't notice unless you're looking for it.

That said, you _can_ make a spring from most any kind of brass, but it won't and can't have the same geometry as a steel or phosphor bronze spring.
