Lead-Free Rosin Core Solder Wire (Sn99.3/Cu0.7) (different models available)

This low melting point, lead-free solder wire is designed to make soldering cleaner, smoother, and more efficient.

With a high-purity tin composition and rosin core flux, it supports reliable electrical connections while reducing spatter, smoke, and odour—helping improve comfort and efficiency during electronic repair, DIY work, and soldering tasks.

Main Features

• Lead-Free Composition: Made from unleaded tin solder suitable for environmentally conscious soldering.
• High Purity Alloy: Tin (Sn) 99.7% and Copper (Cu) 0.3% for stable and consistent soldering performance.
• Rosin Core Flux: Built-in rosin flux cleans surfaces during soldering and improves joint quality.
• Low Melting Point: Enables faster soldering, reduced thermal shock, and improved efficiency.
• Clean Soldering: Less spatter, less smoke, relaxed smell, non-corrosive, and no spattering.
• Wide Application: Suitable for electrical, electronics, circuit boards, DIY projects, and electronic maintenance.
• Smooth Flow: Ensures firm, smooth solder joints with good solderability and insulation resistance.
