With all due respect to laser welding, some jobs just go easier with solder. We manufacture the solders we sell. Right in house. Cadmium has never been an ingredient. We use far more advanced patented metallurgy to create plumb solders that flow in more available temperatures than anyone. For example in 14kt plumb yellow, we have Extreme easy, Extra Easy, Easy, Medium, and Hard flows available. Please enjoy a glimpse into our shop and process. The image on the left is of us heating a steel ingot mold for pouring a bar of gold solder or maybe white gold for sheet. To look at our solders in detail just click the menu up top.
