I like the fact that is lead free and great adhesion to wire without dripping everywhere. ## Features - ROSIN CORE- easy for soldering with rosin core with better flowability, strong soldering joint - LOW MELTING POINT- the melting temperature is about 419 Deg.F, suitable for all soldering tools - ROHS SOLDER WIRE- Lead Free solder for engineer to soldering the electronics - WIDELY APPLICATION- the 0.04in diameter solder wire is common to solder most electronics components or wire, for electrical soldering, repairing, diy - QUALITY SOLDER- Made with alloy Sn99, Ag0.3 and Cu0.7, the silver 0.3% is important for electric conductivity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z2N7ZPB | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #79,946 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #184 in Solder | | Color | Grey | | Customer Reviews | 4.6 4.6 out of 5 stars (217) | | Date First Available | October 13, 2019 | | Included Components | 1.0mm Solder Wire | | Item Package Quantity | 1 | | Item Weight | 1.76 ounces | | Item model number | EST-SD01-1.0LDF50 | | Manufacturer | Enersystec Electric Co.,Ltd | | Material | Alloy | | Outside Diameter | 0.04 Inches | | Package Dimensions | 3.3 x 2.3 x 1.1 inches | | Part Number | EST-SD01-1.0LDF50 | | Performance Description | 50g Alloy Soldering Wire | | Power Source | ac | | Size | 0.04in-1.76oz | | Special Features | Lead Free Solder 0.04in diameter, for electronics soldering, soldering study, Repaire, Production | ## Images ![Solder Wire Lead Free Rosin Core Flux 1.0mm Electronics Soldering Diameter 0.04in No Lead 1.76oz 50g Sn99 Ag0.3 Cu0.7 Flow RoHS Electrical Solder Wire Electric Repair Unlead - Image 1](https://m.media-amazon.com/images/I/61tl0RpDSYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ More solder than I will ever need *by J***M on November 26, 2025* This solder works. It looks like chinesse crap but it works. I even unspooled the whole thing to make sure they didn't weigh down the spool to make it feel heavier, but it's legit and now I need to try and fix it. ### ⭐⭐⭐⭐⭐ great adhesion to wire *by V***U on January 5, 2026* good size and quality. I like the fact that is lead free and great adhesion to wire without dripping everywhere. ### ⭐⭐⭐⭐ Really thin *by S***M on December 22, 2024* I didn't know what I needed. I was soldering wire into a terminal and thought this would do the trick. This is really thin and I used up a ton of it trying to get the terminal filled so I could put the copper wire into it. Just know that this is really thin and probably made for some precision use. ## Frequently Bought Together - Solder Wire Lead Free Rosin Core Flux 1.0mm Electronics Soldering Diameter 0.04in No Lead 1.76oz 50g Sn99 Ag0.3 Cu0.7 Flow RoHS Electrical Solder Wire Electric Repair Unlead - SRA Solder 135 Rosin Paste Soldering Flux For Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Clean Residues with No Goopy Mess (2oz Jar) - Lesnow solder wick braid 10ft Length Desoldering Wick Braid Remover Tool Solder Sucker 1 piece No-Clean soldering Wick Wire Roll and Disassemble Electrical Components --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/186185790-solder-wire-lead-free-rosin-core-flux-1-0mm-electronics](https://www.desertcart.hr/products/186185790-solder-wire-lead-free-rosin-core-flux-1-0mm-electronics) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-21*
