Usage Procedure
Heat base metal with 1-X acetylene feather flame. Melt off small amount of Cronabraze Eagle™ 52 and scrub (tin) area of repair using a clean stainless steel wire brush. Use circular motion of torch when applying buildup or repair alloy. Copper or carbon block is suggested as a chill bar when soldering thin sections. No flux is required.
Technical Tip
Maximum bonding requires getting to the base metal under the oxide layer present on all ­aluminum. To bond to virgin metal, scrub the bonding area with molten ‘52’ alloy or scratch the area with the ‘52’ alloy with the base metal at application temperature. Heavy oxide layers can be easily removed with ‘Flex’ grinding wheels.
After tinning, bring filler to surface at 90° angle and manipulate torch in a circular motion at 45°. Avoid overheating base metal. Use clean torch tip to p
