## Summary description

Dedra 31L92525 solder is a manufacturer's replacement solder product identified by model 31L92525. Intended for electronics and general soldering tasks, it serves as a joining material for electrical components and wires. Use cases include PCB repairs, cable connections and small appliance maintenance where a reliable solder filler is required.

## Long description

Solder wire Dedra 2.5 mm Sn97Cu3 250 g is a lead-free tin‑copper alloy solder designed for manual soldering tasks in electronics, electrical wiring and small metal repairs. The alloy composition of 97% tin (Sn) and 3% copper (Cu) provides good wettability, stable electrical conductivity and mechanically robust joints for components and conductors. Supplied on a 250 g spool with a 2.5 mm diameter, this solder wire is intended for use with soldering irons and stations where a thicker wire is required for larger joints or faster material feed.
Advantages
The Sn97Cu3 composition offers consistent melting behaviour and reduced risk of forming brittle intermetallic layers compared with some other lead‑free alloys. The 2.5 mm diameter enables quicker filling of joints and improved heat transfer from soldering iron tips to workpieces, which is useful when joining larger conductors or when faster application is needed. A 250 g spool provides a practical quantity for repeated repair and assembly tasks without frequent spool changes. The wire is supplied flux‑cored and is compatible with standard flux types used in electronics and electrical work.
Suitable for
Manual soldering of through‑hole electronic components and connectors
Electrical wiring and terminal repairs in appliances and installations
Small metal repair jobs and hobby projects requiring a lead‑free alloy
Soldering tasks where a thicker wire diameter speeds up application and material feed
Key specifications
Alloy composition: 97% tin (Sn), 3% copper (Cu)
Wire diameter: 2.5 mm
Spool weight: 250 g
Form: flux‑cored solder wire suitable for manual soldering
Typical applications: electronics assembly, electrical connections, small metal repairs
How to use
Secure the workpiece and heat the joint with a soldering iron or station set to an appropriate temperature for tin‑copper alloys. Apply the solder wire to the heated joint, allowing the solder to flow and wet the surfaces; avoid prolonged overheating. If the solder is flux‑cored, the flux will assist in removing surface oxides during heating; additional flux can be applied for heavily oxidised surfaces. After soldering, let the joint cool naturally and inspect for smooth, well‑wetted fillets and complete coverage. Clean any flux residues as required by the application or safety standards.
Usage recommendations
Use soldering temperatures recommended for Sn–Cu alloys and select an iron tip that provides sufficient heat transfer for 2.5 mm wire. Work in a well‑ventilated area and follow safety practices for flux fumes and hot tools. For critical electrical connections, verify joint integrity and electrical continuity after soldering.
