331760 - 95/5 Tin-Antimony Lead-Free Solder Wire, 1 lb Spool, 3.2mm

Industrial Grade 95/5 Tin-Antimony Solder for Professional Applications

The Handy and Harman 95/5 Lead-Free Solid Wire Solder is a premium joining material engineered for professional tradespeople demanding high reliability and compliance in plumbing and HVAC systems. Composed of 95% Tin and 5% Antimony, this alloy (ASTM B32 Grade Sb5) offers superior tensile strength and creep resistance compared to traditional lead-based or lower-grade lead-free alternatives. Its specific formulation results in a narrow melting range, which provides the operator with precise control over the flow and solidification of the alloy, making it particularly effective for establishing leak-proof seals in complex piping configurations.

Regulatory Compliance and Safety

In the modern industrial landscape, compliance with health and safety standards is non-negotiable. This solder wire is rigorously tested and certified to meet NSF/ANSI/CAN 372 standards, verifying its safety for use in drinking water system components as mandated by the U.S. Safe Drinking Water Act amendments. Additionally, it complies with EU REACH and RoHS directives, ensuring that your projects meet global environmental and safety benchmarks. The lead-free nature of the wire eliminates the risk of lead contamination in potable water lines, protecting both the end-user and the installer.

Application Versatility

With a diameter of 0.118 inches (approximately 3.2mm), this solid wire is substantial enough to efficiently feed into larger joints found in commercial copper plumbing and brass fittings. Because it is a solid wire, it requires the external application of flux, allowing the professional to select the exact flux chemistry needed for the specific base metal—whether it be a water-soluble plumbing flux for copper or a specialized liquid flux for ferrous metals. This versatility makes it an essential consumable for mechanical contractors working on refrigeration lines, heating systems, and potable water distribution networks.

Technical Specifications

The 1 lb spool provides an ample supply for service calls and small-to-medium fabrication jobs. The silver/gray deposit ensures a clean, professional finish that inspectors and clients expect. By utilizing a Tin-Antimony alloy, this product avoids the softness associated with pure tin solders while maintaining excellent ductility and wetting properties when used with the correct fluxing agents.
