Exotech, Inc.

Exotech-produced Chromium powder has purities ranging from 99.7% to 99.99% and particle sizes ranging from -3 mesh to -325 mesh (6.5mm to -45 microns). Chromium powder production capacity at our facility in Pompano Beach, Florida is 20, 000 kgsmonth. We maintain inventories of: 1-3mm, 2-4mm -50 mesh (-300 micron) -100 mesh (-150 micron) -150 mesh (-106 micron) -200 mesh (-75 micron) -325 mesh (-45 micron) Custom sizing is available upon request. The majority of our products are used for the manufacturing of sputter targets, thermal spray powder, high temperature electrical contacts. The quality and consistency of our Chromium powder is what makes Exotech unique. Products made from our powder are of a higher purity than any other commercially produced Chromium product and are free of voids and pull outs. We are constantly exceeding the standards for the demanding needs of the data storage, flat panel display, and solar industries. The Exotech powdering process is based upon impact milling in a controlled materials environment. This produces a consistent quality product with a chemistry virtually unchanged from the feed material. Custom particle distribution can be achieved by a combination of our multi-stage vibratory screener units and our V-blender homogenizer.

Exotech purchases sputter target scrap from manufacturers, sputter target users, bond shops and tradersdealers from around the world. Through 25 years of recycling sputter target materials, Exotech has the knowledge and expertise to utilize the high purity and unique alloys common to this industry. This allows Exotech to pay the highest prices, while recycling in an environmentally responsible manner. Thermal, Chemical and Mechanical de-bonding are all in-house to stripremove solder and de-bond backing plates. Each target will be analyzed and sorted in-house. Items we regularly purchase as spent targets and production scrap: Tantalum, TaAl, TaNi and other Ta alloys Chromium, CrTaTi, CrMo, CrW and other Cr alloys Cobalt, CoCr, CoCrTa, CoFe, CoZrTa, and other Co alloys Indium Tin Oxide – ITO, Indium, InSn, In containing solders Nickel, NiV, NiCr, NiW, NiFe, and other Ni alloys Titanium, TiAl, and other Ti alloys Tungsten, WTi and other W alloys Molybdenum, MoTa, Mo alloys Niobium, Silicon, Hafnium and Vanadium Ruthenium, Germanium Pure and alloys of Pt, Re, Ir, and Rh IN HOUSE X-RAY FLUORESCENCE FOR RAPID AND ACCURATE ALLOY IDENTIFICATION Exotech provides the necessary logistics for the packaging and shipping of spent targets and production scrap. New and unusual types of sputter target alloys are constantly arriving at Exotech. Our business is based on finding the right method to recycle these unique alloys.
