I am making a 2-part clamp for the quill of an old camelback drill press. The two parts together are about the size of the palm of my hand. I made patterns and they are at the foundry. I have been advised to avoid red brass (95-5-5-5 aka C83600) as it is relatively weak (14 ksi) and I don't want this part to break.
The next bronze they are pouring is C95400, an aluminum bronze with a machinability rating of 0.60 - what does that really mean? It is much stronger (21 ksi). I have to bore it, mill it and drill/tap 2 holes. The machine I have is a Bridgeport type mill from Spain.
Weldability is immaterial in my case.
I really need some help deciding what to choose.
