Specifications Torch/Neutral Flame, Propane Sizes and Packaging (in.) .050 x 1/8 1/16 3/32 1/8 (mm) 1.4 x 3.2 1.6 2.4 3.2 1 lb. packs, 5 lb. packs, 10 lb. tubes. Features Columbia 9G is basically a more versatile alloy than Columbia 8G. Subsequently Columbia 9G would be the better choice of filler metal. Extremely ductile with high thermal and electrical conductivity. Corrosion resistant. Deposits may be tinned or electroplated by hot dipping. Description Phos-copper-silver alloy for poor fit-ups. Applications Columbia 9G is very similar to Columbia 8G, however it does contain more silver (6%). The increased silver content allows for a slightly lower operating temperature and makes Columbia 9G more suitable for varying or “greater than recommended” clearances of .002” - .003”. Most commonly used in copper to copper and copper to brass or bronze tubing or pipes such as found in radiators, air conditioners, refrigerators, plumbing, marine and electrical components. Not to be used on ferrous metals.
