This copper paste solder is technically called phos-copper paste solder. This solder is cadmium and indium free. Sold in a 10 DWT (1/2 troy ounce) total weight syringe. For hard (torch) soldering only. Phos-copper paste solder flows at 1325F, or about the same temperature as a soft silver solder. The alloy has a light brassy color and is used extensively to produce brass military belt buckles. The phos-copper paste is great for use on copper, brass, bronze and mixed metal projects like silver to brass and stainless steel to brass or gold. Date on syringe is mfg date, not a sell by or expiration date. Caution: Contains Fluorides
