20% SREBRA (OTULINA TOPNIKA)
Alloy with high silver content (20%) for joining steel/brass/copper pieces. For assembling badly made pieces. Low-temperature brazing in general.
CAPILLARY-ACTION BRAZING:
Copper-silver-zinc alloy with low melting point for brazing copper and copper alloys, steels and stainless steels. Available in bare or flux coated rods. Extremely flexible coating (it does not crumble when bending the rod).
GAZARGENT 20Si is to be used with an oxy-acetylene, oxy-propane or oxy-butane welding torch with neutral flame adjustment.
