Hello,
I am trying to make a tungsten alloy shield for a gamma source. The whole setup should be UHV compatible. I am thinking of tungsten-copper alloy- HA 195. The question that I have is- how difficult it is to machine this alloy or weld this alloy. The shielding is basically a cylinder with two different OD and one single ID. So either I can get two pieces and get them welded or buy one single piece and get it machined. The total length is ~ 100 mm and the larger OD = 40 mm. The other consideration is that the alloy should be non magnetic. If there is any other tungsten alloy better then HA 195, then I can go for that as well. Look forward to your suggestions.

You could try a possible alternative processing route - KIT have developed Powder Injection Moulding to make tungsten components for fusion applications. It seems to work well.

Both processing and welding of any refractory metal or alloy need in high standard technology and skilled personnel. I suggest to you to address your request to the international manufacturers, who have great experience in this field.
Peter, I am not really looking for tight tolerances. Will that help the situation?
This goes out to both Srirangarajalu and manikandan- do you know of any vendor who could be helpful? I am asking because you guys are from India.
