Silver Sheet Solders-Extra Soft, Soft, Med, Med Hard & Hard-1/4 Oz. Sheets

Silver sheet solder for hard (torch) soldering and brazing of silver jewelry and metalwork. Each sheet weighs approximately 5 pennyweights (1/4 troy ounce / 7.7 grams) and measures approximately 40 mm × 60 mm with a thickness of 0.30–0.33 mm. Choose from five flow points — Extra-Soft through Hard — to match the demands of new fabrication, repair work, or specialty applications such as enameling.

The grade names Extra-Soft, Soft, Medium, Medium-Hard, and Hard describe relative flow temperatures within this solder line. Each successive grade flows at a higher temperature, which generally produces a stronger bond. Note that flow point designations can vary between manufacturers; one maker's Medium may flow near another maker's Hard.

Extra-Soft solder (also called Extra-Easy) produces a pale yellow appearance and leaves a visible seam on silver. It is recommended for eyeglass repair and applications requiring the lowest flow point. Extra-Soft is the only grade in this line that contains cadmium. All other grades are cadmium-free.

Soft solder is also referred to as Easy solder.

Hard (IT) solder flows at 1490°F (810°C), above typical enameling firing temperatures, making it suitable for soldering findings onto pieces prior to enameling. Ensure this solder does not contact enamel directly — zinc-bearing solders can cause enamel to bubble if contact occurs.

Choosing a grade: When manufacturing, use the hardest (highest flow point) solder you can so future repairs can be made with lower-temperature solders. When repairing, use the softest grade possible, since the solder previously used is unknown.

Features

• Five flow point grades available: Extra-Soft, Soft, Medium, Medium-Hard, and Hard
• Sheet form for easy cutting and sizing to fit any seam
• Each sheet weighs approximately 5 DWT (1/4 troy ounce / 7.7 grams)
• For hard (torch) soldering and brazing only — not for soft soldering
• Hard grade functions as IT solder for pre-enameling applications
• All grades except Extra-Soft are cadmium-free

Notes

• Extra-Soft (804-404) contains cadmium. All other grades are cadmium-free.
• WARNING: Part #804-404 can expose you to cadmium, which is known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, visit www.P65Warnings.ca.gov.
• Hard (IT) solder must not come into contact with enamel during the enameling process — zinc-bearing solder contact may cause bubbling.
