Applied Physics Technologies specializes in float zone refining of refractory metals, transition metal carbides, LaB6 and CeBix. We have extensive facilities for growing single crystal rods of these materials. APTech also centerless grinds and in some cases electrochemically etches rods to exacting dimensional specifications.

Applied Physics Technologies offers both single crystal tungsten wire and single crystal tungsten rod. Diameters range from 0.12 mm (etched wire) to 2.5 mm (as-refined rods). Orientations offered include (100), (111) and (310).

Single crystal tungsten wire is zone refined and axially oriented to the specified crystal plane within 2*. Metal impurities are less than 30 parts per million by weight. Wire is centerless ground, electrochemically etched to the specified diameter, +/- .0003", and then cut to the specified length +/- 5%.

Lead times vary depending on stock on hand. Custom orientations are also available. Call 503.434.5550 or email APTech at sales@a-p-tech.com for a price quote.

Mo, Pt, Ir, Re, Ta, and other single-crystal refractory materials are usually sold as-refined; ~1-mm diameter rods.
