Kram Member Messages 8,822 Location Sussex Feb 27, 2026 #2 See what temp they melt at - a temp controlled furnace would be best slowely inch up until it melts. The good silver rods melt below 650-700c. Or take to a scrappy, who has an xray gun. Or someone with a SEM.. They look a bit corroded to be silver types, also 450mm is short - brazing rods are normally 600mm lengths.
