Which of the following filler metals shall be used to braze copper-to-copper joints in medical gas and vacuum distribution piping?

The BCuP series of filler metals is specifically formulated for brazing copper-to-copper joints in medical gas and vacuum distribution piping. This series contains phosphorus, which helps in providing a good flow and strong bond between copper parts. The melting points of BCuP alloys are also well-suited for joining copper, ensuring that the base material is not compromised during the brazing process.

Using the BCuP series ensures compliance with industry standards for medical gas systems, as these joints require high integrity and resistance to corrosion. The properties of BCuP alloys facilitate the formation of a strong, durable joint that is essential for the safe operation of medical gas distribution systems.
