Cronatron™ 23 Copper and Steel Flux Coated Brazing Rod

A selection of brazing alloys for joining cast iron and brazing sheet metal.
Superior Advantages
• Solid, dense deposits that can be machined
• Free-flowing for thin lapping and butted metal joining
• No base metal dilution making tough cast iron repairs possible
Versatile, thin-flowing
Flux Coating Color: Blue
Tensile Strength: Up to 68,000 PSI
Bonding Temperature: 1,400°F to 1,600°F (760°C to 871°C)
Recommended Flux: F21 (if needed)
Typical Applications
• Sheet metal and auto body repairs
• Engine heads and blocks
• Piping, plumbing and pumps
• Gears, sprockets and pulleys
Usage Procedure
Clean joint areas thoroughly. Heat metal with neutral flame until flux liquifies. Base metals should be dull red as Cronabraze™ 30F commences to penetrate the joint. Use rapid weaving motion with torch to deposit alloy drop-by-drop. Do not concentrate heat enough to melt base metal. Remove flux residue with water.
