Bar Solder

Drop these bars into solder melting pots for a continuous supply of solder without the tangles of wire solder. Made of 50/50 tin-lead alloy, they wet easily to produce strong joints on copper, brass, and steel. Since these bars don’t have a flux core, you can use them with your flux of choice.

Bar Solder for High-Temperature Applications

This solder is commonly used in solder melting pots. It keeps its strength in applications where vibration and frequent and extreme temperature changes occur, such as in water lines and refrigeration equipment. It does not have a flux core, so you can choose the flux that works best for your application.

Lead-Free, Flux Required

Lead-free solder is safer to use than leaded solder and helps meet industry regulations.

High-Melting-Point Bar Solder for Electronics and Electrical Applications

With a high melting point, this solder won't remelt when you solder successive joints with another solder. It's ideal for solder melting pots. The leaded alloy wets and flows better than lead-free alternatives for reliable electrical connections. Added silver increases joint strength and resistance to fatigue. Without a flux core, you can choose the flux that gives you precise control over coverage and cleanliness.

High-Density Low-Melting-Point Solder

This bismuth-tin solder has similar performance properties to lead solder, but is also safe for use in food-processing equipment and copper water pipes. It has a lower melting point than most solders, so it’s good for sensitive assemblies, such as semiconductors and electronic components, as well as for step soldering with traditional solders. However, it’s less thermally conductive than other metals and more brittle than lead. Flux isn’t required, but for easier cleanup use it with no-clean soldering flux. Do not use this solder on drinking water pipes.

Lead-Free, No Flux Required

Lead-free solder is safer to use than leaded solder and helps meet industry regulations.

1% Silver—Solder with 1% silver forms stronger bonds than solder without silver. It’s also more malleable and ductile. However, it has a higher melting point, so it takes longer to solder.
