These solder alloys all contain lead. While many of these solder alloys have excellent working properties, because of health concerns, and RoHS legislation, we urge you to consider using Lead-Free Solders wherever possible. For applications that require the characteristics of a lead containing solder, please be certain to research the relevant regulations governing the use of lead.
