Solder Wire

Solder Wires typically have either a solid core or a core that is on the inside containing flux. This containing flux is designed to improve electrical contact and mechanical strength in solder joints. EIS offers flux-cored solder wire with rosin, mildly activated rosin, no-clean, water soluble, and inorganic flux. The two main types of solder wire are Leaded and Lead-free. Leaded solder wire is typically a 60/40 mix of tin/lead. Lead-free solder wire is becoming more prevalent in use because of the health hazards of lead, but it has a higher melting point and is a bit harder to work with.

EIS carries a wide variety of high quality solder wire from top suppliers Kester Solder

and Zephytronics to meet many different soldering needs. With the variety of solder wire requirements, you can be confident that EIS has what you need.
