Balls

How are balls made?
I want to make some balls from probably monel or maybe brass/bronze, about
10 - 12 mm dia or so. They have to be pretty accurate and with good surfaces
(they are for high pressure ball valves).
Any ideas? Anything like that available elsewhere? so I don't have to make
them and can just buy them at non-silly prices?
Thanks

If the price doesn't sound too bad, you might try: McMaster-Carr

they carry all kinds of balls, e.g. Item No. 9617K42. (Use their search box for other sizes and/or materials). They cost about £7.50 for 25 - I sure wouldn't spend the time making them for that :-).

In the US most tooling suppliers carry a variety of brass and stainles
steel balls. Bronze can be found but is quite a bit more expensive. The stainless come in a variety of grades including machinable grades. Most of the low cost ones are +/- 0.0002 inch tolerance. Both th brass and stainless cost about US$15 for a package of 25 in 7/1 diameter size. I have seen metric balls also, but they are not commo in the US. I would guess the UK tooling suppliers would have them fo similar prices. For reference go to

and search fo brass balls.

Here is one selling the most weird balls in almost any material. Need monocrystal balls? Hollow? Glass? Whatever?
Don't know about the prices.

These folks have bronze balls in their catalogue - I've never dealt with them yet, but planning to!

Bearing Services Ltd (BSL) will either stock or be able to get them for you in a variety of materials incl Phosphor bronze & stainless.
I suspect any bearing supplier will do the same - yellow pages would be my first place to look.
Good luck
