I've been using Invar 42 that a very nice gentleman in Delaware sent
me a couple or 4 years ago . Does wonderful on CI , but is also very
good for welding tungsten electrodes to SS mandrels to be used to make
glass beads . I've also got some strips cut from an old CI stove door
that work well . But that ain't going to help the OP , who doesn't have
a TIG welder .
