Inside every solder is a material called flux which helps improve the electrical contact and mechanical strength of the solder. This flux can either be rosin or acid core. While rosin core contains mild flux suitable for most electrical soldering, acid core should not be used on your electronics as it contains an aggressive type of flux that will damage your circuits and components. It’s more ideal for plumbing and metal work. So, before you settle for a choice, make sure you clearly identify what soldering job you want it for.
These are the main factors you will need to consider before you decide the best fit for your home improvement needs. We’ve got you covered with a list of the best that will serve you well.
You may have noticed (or not) that certain solders have peculiar features and work better on some jobs than others. Tantamount to an excellent soldering job is mastering what solder best fits a job at hand, be it plumbing or electrical.
Best Solder Wire Overall
