Max Thermal Temperture for Bronze Alloy UNS C67300
Max Thermal Temperture for Bronze Alloy UNS C67300
(OP)
I need assistance, what the max temperature that the above Bronze alloy can be heated for shrink fit application.
that will not affect material properties.
tried to do a search, but found no linked data.
Please Advise
Thank You

Also, any plating/coating on the part will dictate an upper-temperature limit of 250--500F... depending on the plating/coating.
Copper alloys and most coatings tolerate immersion in LN2. Any good reason 'shrink fitting' can't be accomplished using LN2 [~-220F?]... instead of high heat?

Thanks for the reply, the bronze part is not coated or plated, and the part has an Internal diameter that is shrink fitted to a shaft.
the shaft is place in cold box to -90 deg. F , but that said it is assembled by our customer. and our customer is having issues. I needed the temp's
so that I could calculate the shrink fit verses the amount of press. I needed to suggest to them to use LN2 for the shaft and to heat the Bronze alloy
to a higher temp. to obtain the proper clearance. I had did an extensive search and could not find reliable data. it was not on the material data sheets.
but the information given in assistance is very valuable, and I appreciate it.
by the way the shaft is AISI 9310 with carburize surfaces prone to cracking if excessively pressed.

Heated/chilled metal parts, especially ones with small mass or thin sections, can cool down/heat up quite quickly while being handled. So minimizing the amount of time required to fixture and assemble the parts is important. It is best to use a dedicated fixture designed to make the thermal fit procedure quick, easy and consistent.

Yep I am aware of that, I don't believe our customer is. :) why I inquired about the question for the max temp.
I have being doing this for while. bronze alloy is not common for our type of product.
