HH96010 - 94/6 Tin-Silver High Strength Solder 1/8" (3.2mm) 1lb Spool

High-Performance 94/6 Tin-Silver Solder for Industrial Applications

The 94% Tin / 6% Silver Solder (3.2mm) is a premium soft soldering alloy designed for applications requiring superior strength and ductility. Unlike standard tin-lead or 95/5 solders, this 6% silver formulation offers significantly higher tensile strength and elongation, making it the preferred choice for critical connections in HVAC, refrigeration, and industrial piping systems. The 3.2mm (1/8 inch) diameter is substantial enough for larger pipe fittings and industrial fabrication, providing excellent coverage and capillary action.

One of the primary technical advantages of this alloy is its melting range. It begins to melt at approximately 430°F, which is considerably lower than brazing alloys (which typically require temperatures above 1100°F). This lower temperature application prevents the annealing of copper tubing and minimizes the formation of heat-affected zones (HAZ) in sensitive base metals. Despite the low heat input required, the resulting joint exhibits strength characteristics often comparable to brazing in specific applications, particularly regarding vibration resistance.

Technical Specifications & Compliance

This solder is completely lead-free, making it compliant with Safe Drinking Water Act requirements and suitable for use in food processing equipment and potable water lines. The silver content not only boosts mechanical strength but also improves corrosion resistance and electrical conductivity. It is compatible with most ferrous and non-ferrous metals, including steel, stainless steel, copper, brass, and bronze (excluding aluminum and magnesium).

Recommended Usage

• HVAC/R: Ideal for refrigerant lines where vibration is a concern.
• Plumbing: Safe for drinking water systems requiring high-pressure ratings.
• Fabrication: Excellent color match for stainless steel projects.

For optimal results, this solder should be used with a high-quality flux designed for silver-bearing alloys. The 1lb spool provides ample material for professional contractors and industrial maintenance teams.
