Tix Flux 1/2oz Tix Flux is specifically designed to work with Tix Solder, a low melting lead/tin based solder. With Tix Solder's melting point of only 275*, it's important to have a flux which flows at a much lower temperature, and this product is an ideal match. Tix Flux can be used with almost any soft solder, and cleans up with water. Contains: 1/2 fluid ounce Brush Included
