Below are listed the primary families of solder alloys. For additional information please contact us.
Soft Solder Alloys
| Tin-Silver Combination |  |
Developed as a lead-free alternative, Tin/Silver alloys offer superior strength compared with other solders. Excellent flow makes the switch from lead an easy choice. Choose from 96/4 and 95/5. |
| Tin-Antimony Combination | |
Also developed as a lead-free choice, this alloy provides improved performance over the Tin-Lead alloys, and is more economical than the Tin-Silver alloys. Available in composition 95/5. |
| Tin-Lead Combination | |
Used for centuries as the primary alloy for soldering, this family offers an extensive variety of options. Environmental and health concerns over lead have limited its use. Choose from 50/50, 40/60, 60/40. Also available in paste form. |
| Tin-Zinc Combination | |
Primarly used to join "tough-to-solder" aluminum alloys. Ability to join aluminum alloy to dissimiliar metals and to itself. |
| Tin-Bismuth Combination | |
Formulated as eutectic 58Bi/42Sn alloy, this solder paste is lead-free, halogen-free, and has low activation temperature, with exceptional wetting performance in air reflow. |
