Welding Fluxes

The Anti-Borax Company was founded in 1902. Today, 100 years later, the fluxes are still used for bronze brazing, cast-iron welding, and other applications used for metal joining in blacksmithing and forge processes. Most of the compounds we offer are under the Anti-Borax brand name.

Anti-Borax Super Stable Weld, 1 lb

!

A mixture of forge borax and a welding compound. There is little metal filings and works best when welding in a gas forge. It is basically the EZ Weld, Cherry and Climax compositions, but with a lower metal leading (12%). It is used in forge applications that require a lower metal concentration in the flux. It works like EZ Weld in most forge welding  processes, and can be used in a wide variety of applications.

Anti-Borax Forge Borax
!

It is formulated for forge welding of stainless steel and helps remove oxides and make steel easier to work with at temperature. Excellent for finishing heats, toe caulk and plow work.

Item #: FB1 or FB5

Anti-Borax E-Z Weld Flux, 5 lb
!

Adheres to metal at a low heat and is equally good for lap, split, butt, or jump welding. It enables blacksmiths to weld tool steel, plow open hearth and bessemer at significantly lower temperatures than other compounds while making strong, smooth welds. Can be used with steel as well as iron.

Item #: CW1

Mustad Sure-Weld, 12 oz can
!
A mixture of forge borax and a welding compound. There are little metal filings and works best when welding in a gas forge. It is, however, equally effective when used in coal forges. Only a small amount is needed for each weld, so it is both effective and economical.

Item #: ABBF1

Acro-No Acid Flux, 9 oz
!

Directions for Babbitt: Heat Babbitt to 850 degrees F and throw liberal amount of flux on surface. Stir vigorously from top to bottom with skimmer. Then stir horizontally in circular manner to collect skimmings at center and skim off. Repeat until there is a clean separation of metal and oxides.

Directions for Zinc: Heat Zinc until quite molten and then follow the same instructions for Babbitt.

Note: Flux produces a white smoke that is harmless, but ventilation is recommended.
