Tight dimension alloy
Tight dimension alloy
(OP)
Does anyone know or have suggestions on which alloy would be best for machining tight dimensions, less than 1mm wall thickness, with no nickel, and is the hardest I can get. The application is a hollow ring that will contain electronic components. So I really need a hardness that will last, and no flexibility, or very little.
I really wanted to use ALON ceramic, but I cannot find a supplier, and they wont email me back, and spinnel is probably too soft. So if anyone had suggestions for something clear, it would be a great plus.

While hardness sounds good some toughness is needed. Maybe a toughened Zirconia would be the best balance.
They would sinter blanks and then finish grind to size, it isn't cheap.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Great work.

What about other materials? I heard inconel would be strong enough at half a millimeter.but, its mostly nickel. Maybe spring steel? Or a titanium alloy?

When B&B makes tooling for us it is usually single pieces.
If you want a steel look for 300M or maraging 250. They are real high strength materials. The maraging steels contain some Ni but it is below the levels of concern for Ni sensitivity.

I will look more into the 250M. It looms like it could work. But for now im gonna take some carbide to these zirconia and see if they shatter at small dimensions and a bump on the counter.

It won't like being flexed or loaded with a sharp point, but broad loads will have little impact on it.
