HT1 - Unibraze HT-1 Black Silver Brazing Flux Paste - 1 lb Jar

Tackle High Heat and Carbides with Confidence

When your brazing job involves high temperatures or stubborn materials like stainless steel and carbide, standard white flux just won't cut it. That's where Unibraze HT-1 Black Flux comes in. This 1 lb jar of high-temperature paste is formulated to keep working when the heat turns up, rated for use between 1450°F and 2000°F. It is the go-to solution for welders and fabricators working on carbide tipping, heavy machinery parts, or any project where the torch stays on the metal for a long time.

The 'Black' flux formula is enriched with boron, giving it the stamina to resist burning out during long heating cycles. This means you get consistent protection and wetting action from the start of the braze to the finish, reducing the risk of voids or weak joints. It cuts right through the tough oxides on stainless steel and nickel alloys, ensuring your silver solder flows exactly where it needs to go. Whether you are using an oxy-fuel torch or an induction heater, HT-1 gives you the control and reliability needed for professional-grade silver brazing.

Why Choose HT-1 Black Flux?

• High Heat Tolerance: Won't break down or char at 1800°F like standard flux.
• Carbide Friendly: The best choice for brazing tungsten carbide tools.
• Longer Life: Stays active during extended heating, perfect for thick parts.
• Easy Cleanup: Residue washes off with hot water.
