Solder wire comes in two main types: lead-based and lead-free, with lead-free being the more popular choice in electronics due to environmental concerns. Within these, there are variations like flux-core and rosin-core, which contain a flux to assist with soldering.
Here's a more detailed breakdown:
1. Lead-Based Solder:
Composition: Traditionally made from a tin-lead alloy, often in ratios like 60/40 or 63/37.
Pros: Easier to work with due to lower melting points and better wetting.
Cons: Lead is a toxic metal, so it's not ideal for many applications.
Applications: Used in electronics, plumbing, and other applications where lead is permissible.
