with a copper self fluxing brazing rod type suggested by AWS
In order to braze the metal has to melt and the melting point of brass is 900-940*C depending on it's content.
The tubing on the brass instruments is curved to get a long tube into a short length.
brass
The French Horn is made of brass tubing. Basicly, the Horn is a chunk of of brass tubing.
NO but you will need some type of sealent OR braze or soldering
Clean the base metal use a high temperature flux using a torch capable of getting the base metal almost cherry red and if you braze the joint properly your tensile strength should exceed 87,000
The valves in a brass instrument re-direct the air into different parts of the tubing. Each valve controls a different part of the instrument. The longer the tubing, the lower the note will be.
40 times more expensive then copper tubing
To braze brass effectively and efficiently, follow these steps: Clean the surfaces to be joined thoroughly. Apply flux to the joint area. Heat the brass pieces evenly with a torch until they reach the brazing temperature. Add the brazing rod to the joint, allowing it to flow into the gap. Allow the joint to cool slowly to prevent cracking. Inspect the joint for any defects and make any necessary adjustments.
The modern family of brass instruments can be broken into valved brass instruments (trumpet, horn, euphonium, tuba) and slide brass instruments (trombone). Brass instruments could also be broken up into Cylindrical bore (constant diameter tubing like the trumpet and trombone) and Conical bore (increasing diameter tubing like the horn, euphonium, and tuba).
It has the shortest tubing and therefore the highest resonance.
