lödtråd

Lödtråd, often referred to as solder wire, is a consumable material used in soldering. It is typically a thin rod or wire of metal alloy, most commonly tin and lead, though lead-free alternatives are increasingly common. The primary function of lödtråd is to create a metallurgical bond between two or more metal components, forming an electrical connection or a mechanical joint.

The composition of lödtråd is crucial to its performance. The melting point of the alloy determines the temperature required for soldering, and different alloys offer varying strengths and electrical conductivity. Flux, a cleaning agent, is often incorporated into the core of the lödtråd. This flux removes oxides and impurities from the surfaces to be joined, allowing the molten solder to flow and adhere properly.

Lödtråd comes in various diameters, suited for different soldering applications. Thicker wires are generally used for larger components and higher heat applications, while thinner wires are ideal for delicate electronics and intricate work. The choice of lödtråd depends on factors such as the materials being soldered, the required strength of the joint, and the operating environment of the final product. Common lead-free alloys include tin-silver-copper or tin-copper.
