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.
