I cannot comment specifically on the Zink, but
typically chrome-moly tubing should NOT be brazed.
The brazing material enters the grain structure and
weakens it. It may look perfect but actually be weak.
Brazing, expecially with nickel-bronze, is an
excellent method for joining mild steel tubes. Gas
welding, where the parent metal is actually melted,
can be used with either chorme-moly or mild steel.
