Solder wire is a versatile and useful tool. It comes in different materials, each suitable for different uses. Whether you’re using it to do plumbing work, work on computer parts, or even make jewelry, solder wire can be an important factor in all of these DIY scenarios. Check out the information below for guidance on finding the right solder wire for your specific needs.

How to Choose Your Solder Wire

Here are some things to keep in mind when choosing your solder wire:

  • Material: There are two main types of solder wire: lead-based and lead-free. Each of these types has its advantages. Lead solder wire is ideal for reducing cold joints, while unleaded solder wire works well in moist environments. Before choosing your solder wire, decide which property will work best for your project’s requirements.
  • Alloy Ratio: Lead alloy solder wire is a mixture of lead and tin, and it typically comes in two different alloy ratios: 63/37 or 60/40. While both ratios are ideal for working with electric and plumbing components, 63/37 is more eutectic, so it is useful when the components move while cooling.
