Where this product is used

Solder selection depends on the application — electrical, plumbing, or general fabrication — and the required joint strength.

• Electrical and electronics soldering in trade and industrial environments
• Plumbing and HVAC copper joining operations
• General soft-soldering and tinning applications

Selecting the right option

60/40 tin-lead solder remains the standard for electrical work where permitted; lead-free solder is required for potable water plumbing. Match flux core specification to the application — rosin core for electronics, acid core for metalwork.
