Q. How do I
TIG weld alloy C91000?
A: For TIG welding, you can use
our Phos Bronze A or our Silicon Bronze rod. Phos
Bronze A gives better color match. Silicon Bronze
gives stronger welds. The TIG welding temp. for
both of these filler metals is a little higher than
the melting point of the C91000 (1505 Solidus 1760
Liquidus). Because of this temperature question,
and depending on the thickness of the welded part,
you may want to consider brazing. To braze C91000,
you may use our Phos Copper 0 alloy.
