Handy & Harman brazing alloys in powder form.
Handy & Harman's powder atomization plant is among the most modern in the world. The atomization process is conducted in an inert gas atmosphere. As a result, the brazing alloy powders are exceptionally clean and free of oxides and impurities. Most Handy & Harman brazing alloys can be supplied in atomized forms. Control of particle size is extremely close. The powders are supplied in all standard mesh sizes, and may also be furnished, with the same close controls, to size limitations specified by the customer. Filed powders, produced in coarse-sized particles, are also available. A range of atomization equipment at the Handy & Harman plant enables us to meet wide variations in customer requirements---rapidly and economically. The highest quality of brazing alloy powders is assured be a combination of experience, advanced equipment, and continual research into the latest techniques of melting and automation.
