Lead-free solder for HVAC work

This lead-free solder wire contains 4 percent silver and 96 percent tin, supplied on a one-pound spool with a 0.118-inch diameter. It meets ASTM B-32 Sn96 and NSF 61 standards and has a melting range of 430 to 580 degrees. The alloy is intended for HVAC soldering applications where lead-free materials are required.

Check joint fit and heat source before ordering

Verify that the 0.118-inch wire diameter suits the joint clearances in your piping or fittings. Confirm your torch or soldering iron can reach and hold temperatures within the 430-to-580-degree melting range for consistent flow. Ensure the piping material and flux you plan to use are compatible with a Sn96 silver-bearing alloy.

Replaces leaded plumbing solder in potable-water

This spool replaces traditional lead-based solders when codes require lead-free joints for drinking-water lines or HVAC refrigerant piping. The jump is worth it when local regulations mandate NSF 61 compliance or when the specifier calls for an ASTM B-32 Sn96 alloy. It is not for buyers who need a leaded alloy for non-potable sheet-metal work or for electronic circuit-board assembly.

Questions about this item

What comes in the box and is flux or any other accessory included?

The box contains a 1 lb spool of 0.118 in diameter lead-free solder wire composed of 96 percent tin and 4 percent silver. No flux core or separate accessories are mentioned in the specifications.

Should I choose a different diameter or alloy for general HVAC work?

This spool uses a 0.118 in wire diameter and a Sn96 alloy with 4 percent silver, meeting ASTM B-32 and NSF61 standards for HVAC soldering. Other diameters or alloys are not described in the product data.

What does the 430 to 580 melting range mean when I am making a joint?

The alloy melts between 430 and 580 degrees, giving a working window where the solder flows into the joint before fully solidifying. This range suits copper piping and HVAC connections requiring lead-free compliance.
