Brass for high temperatures

[besc]

I need to make a part for a leather working company. The 2 in cube piece of brass has 2 half in round heaters in it that heat the brass to 1100 deg F. This piece is mounted in an anvil that has a 3/16 slot in it and a pice of steel mounted in the slot for melting together whatever it is they do, dont know. The person doesnt know what kind of brass it is and I was wandering if anyone might know what kind it might be and also the machining problems that there might be. My guesses are 464 and 260 but this is just a quess on my part. Any help would be both appreciated and educational. Thanks. Mike.

They might be using silver solder or silver braze to actually fuse the brass and steel parts together.

Depending on the alloy of silver used, 1100F might enable you to remelt/reflow brass partst that had beened "tinned" with an appropriate grade of silver solder.

I doubt seriously if simply heating brass to 1100 and then touching it to steel would result in a fused/bonding at the interface without the benefit of an appropriate solder or brazing filler material.

Sorry about the misunderstanding. The steal part is held in the brass by set screws. The heat is transfered from the 2by2by2 brass peice from 2 heaters mounted in the brass cube to the metal peice. My question is what type of brass this might be for this application since they nor I know. This is a leather working shop. Mike.

All brasses and most bronzes have pretty near the same melting point and thermal conductivity so I think go with the one that is easiest to machine.
