Kruspe Material

[dorutzzu92]

Hello guys,

Someone can give me some info about the Kruspe Material, ( Thein K-style material)

How is it? I'm fixet to order a Thein Belcanto model, but not sure about the material to go with, i am oscilating in red brass or k-style material

Many Thanks

Best option would probably be to email Thein about it, or talk to a Thein dealer.

Or you could google:

"Thein “Kruspe-style” metal
In the 19th century, the original Kruspe metal was preferred for trumpets and trombones among many brass alloys. It has a high copper content. Thein carried out a metallurgical analysis of this no longer available alloy and revived it."

I would wager you will not get an answer regarding what the metal actually is. They went through the trouble of finding out what it is, and it would probably be proprietary information.

Besides that reasoning I could also imagine they won't share it because there might not be so much magic about it. Potentially the difference is more in the processing than in the actual material? I am thinking of the heating and hammering processes involved. This is just pure guessing. In the end it matters how it plays.

And the (original) old German trombones that I own have some qualities that others don't.

This is also true. I can't imagine it would be that dissimilar from current metals, or they would have trouble sourcing it in quantity. Unless of course, they have found a small foundry willing to make custom alloys.

I remember when Kanstul did a bunch of research and experimentation to recreate the alloys by York when they made their legendary tubas. I wonder what ever happened with that information.
