69050190 - ESAB All-State 155 Silver Solder Coil 1/16" (Pack of 12)

Premium Silver-Bearing Solder for Critical Applications

The ESAB All-State 155 is a high-performance silver-bearing soft solder designed for maintenance and fabrication professionals who require superior strength and corrosion resistance without the high heat input of brazing. This product is supplied as a package containing twelve (12) individual 2 oz coils, each with a 1/16-inch diameter, making it an economical choice for workshops with recurring soldering needs. The alloy is engineered to bridge the gap between standard lead-tin solders and high-temperature silver brazing alloys, offering tensile strengths of up to 25,000 psi.

One of the defining characteristics of the All-State 155 is its low melting point of approximately 430°F (221°C). This low temperature allows for the joining of delicate or thin-walled components with minimal risk of warping, distortion, or metallurgical damage to the base material. It is particularly effective on stainless steel, where it provides an excellent color match that remains bright and tarnish-free, unlike common lead-based alternatives. The formulation is completely free of cadmium, lead, and zinc, making it non-toxic and suitable for use on food handling equipment, medical devices, and potable water systems.

Technically, this alloy exhibits excellent wetting properties on a wide variety of metals, including steel, stainless steel, copper, brass, bronze, and chrome plate. It is also capable of joining dissimilar metals effectively. When used with the appropriate flux (typically All-State 39), the solder flows smoothly and creates neat, leak-proof joints. This product is an essential inventory item for MRO operations involving refrigeration, HVAC, food service equipment repair, and precision instrument fabrication.
