Description

An exceptionally high strength flux coated brazing alloy which can join high alloy steels as well as copper based alloys.

ProCus 68F – Exhibits a tensile strength beyond that of ordinary brazing rods yet is thin flowing to provide high strength joints on ferrous and non-ferrous materials.

• Superb capillary action – flows almost as easy as silver solder.
• Can be easily applied to tool steels, bronze alloys, cast irons.
• Produces joints of high density deposits.
• Low application temperature minimises distortion.
• Low melting point enables gaps to be bridged.
• Greater coated for ease of application.
• Dense deposits without porosity.

ProCus 68F alloy is a must for use in maintenance where high strength joints are essential.

A unique alloy rod and flux combination which is formulated to provide high tensile strength joints on ferrous and non-ferrous materials

The brazing repair of many materials and components is often considered a last resort by many welders. Often the reason is because of poor experiences with jobs completed with ordinary brazing rods. Many brazing materials exhibit poor tensile strength and poor wetting ability and so, because of these factors, the integrity of the brazed joint is often poor and leads to joint failure, particularly on large jobs.

A significant benefit with the ProCus 68F flux and alloy combination it that it will produce a joint of high integrity. The highly active surfactants in the 68 flux will first remove dirt and other contaminants from the surfaces and from within the grain boundaries of the materials to be repaired. Once this cleaning action has been completed, the alloy, because of its capillary action, will flow and readily wet to the cleaned metal surfaces, forming a high strength, tenacious bond, even on refractory materials like tungsten carbide.

The ProCus 68F alloy exhibits an extremely narrow plastic range. That is the difference between the alloy’s melting and solidification temperatures.

Ordinary copper based brazing alloys freeze from the melt very slowly, potentially causing various elements to solidify separately and thus weakening the bond. Because of the ProCus 68F alloy’s superior capillary action, the molten alloy will flow quickly through the joint being repaired but, because of its narrow plastic range, the molten alloy will solidify extremely quickly, preventing segregation of the elements and forming a strong tenacious bond.

The micro-structure of the brazed joint deposit will be homogeneous and so providing the highest strength joint possible of any brazing alloy. The high strength nature of the joint enables the repair of parts like band saws, drill bits, chain links, steel tubing and many other components types.
