Designed for professional electronics work, it offers superior wetting, minimal spatter, and leaves clear, non-corrosive residues that typically require no cleaning. With a melting range of 227-229°C, this spool delivers reliable, eco-friendly soldering performance ideal for precision tasks. ## Description Kester 24-9574-7610 Solder Wire, No Clean, Lead Free, K100LD, 3.3%, 0.020' (0.50 mm), 275 Series Kester 275 Flux-Cored Wire Product Overview:Alloy: Sn99.3Core Size: 66Flux: 3.3%Kester 275 No-Clean Flux for cored solder wire was developed to provide superior wetting performance for hand soldering in the electronics industry. The chemistry is based on some of the same principles that have been safely used for years in mildly activated rosin fluxes. The use of 275 No-Clean Flux results in an extremely clear post-soldering residue without cleaning. The unique chemistry in 275 was also designed to reduce spattering common to most core fluxes. 275 can be used for both lead-free and leaded soldering. 275 is classified as ROL0 per J-STD-004.Performance Characteristics:Low spatteringLow smoke and odorColorless translucent residuesExcellent solderability and fast wetting to a variety of surface finishesClassified as ROL0 per J-STD-004BCompliant to Bellcore GR-78CleaningThe 275 flux residues are non-corrosive, non-conductive and do not require removal in most applications. IPA will not clean the residues off the surface of the circuit board after the soldering process. If removal is required, a saponifier or cleaning agent specifically designed to clean a no-clean flux is required to clean the residues.SpecificationsWire Diameter: 0.020 in (0.50 mm)Alloy Name: K100LDFlux %: 3.3 %Flux Type: No CleanLead Free: YesHalogen Content: HalogenSeries: 275 SeriesAlternate Product Number: K100LD, 2495747610Alloy Type: Eutectic AlloysComposition: 99.3% Tin, 0.7% CopperCore Size: 66Liquidus Point: 229 C (444 F)Melting Point: 227 C (441 F)Melting Range: 227-229 C (441-444 F)Package Type: SpoolShelf Life: 1095 daysWeight: 1 lb (0. ## Features - Wire Diameter: 0.020 in (0.50 mm) - Alloy Name: K100LD - Flux %: 3.3 % - Flux Type: No Clean - Lead Free: Yes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FGHTX5A | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #93,261 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #214 in Solder | | Color | Green Label | | Customer Reviews | 4.7 4.7 out of 5 stars (27) | | Date First Available | September 27, 2013 | | Included Components | 24-9574-7610 | | Item Package Quantity | 1 | | Item Weight | 1.05 pounds | | Item model number | 443-843 | | Manufacturer | Kester | | Material | lead | | Part Number | 443-843 | | Power Source | See Product Details | | Product Dimensions | 2.3 x 2.5 x 2.7 inches | | Size | 1 Pound Spool | | Style | Foldable UV/White Beam | | Usage | Professional | ## Images ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Image 1](https://m.media-amazon.com/images/I/81+FtGYz3GL.jpg) ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Image 2](https://m.media-amazon.com/images/I/81B09qc8PPL.jpg) ![Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Image 3](https://m.media-amazon.com/images/I/81k9m+QTnWL.jpg) ## Frequently Bought Together - Kester 24-9574-7610 K100LD Lead-Free No Clean Wire Solder.020" Diameter-Low Cost Alloy - Kester443-845 24-9574-7618 K100Ld Lead-Free No Clean Wire Solder.031" Diameter-Low Cost Alloy - Thermaltronics TMT-TC-2 Tip Tinner (20g) in 0.8oz Container --- ## 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.tn/products/20138570-kester-24-9574-7610-k100ld-lead-free-no-clean-wire](https://www.desertcart.tn/products/20138570-kester-24-9574-7610-k100ld-lead-free-no-clean-wire) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
