Hoffman Materials, Llc

In the fall of 1932, Philip Reynold Hoffman built, as a hobby, saws for cutting petrified wood. At the request of a local “ham” radio operator who needed a quartz wafer to keep his transmitter on the frequency channels allotted to him by the government, P. R. made his first crystal. The demand for these precision-cut crystals became so great that in 1938, the P. R. Hoffman Company was founded. Over time, ownership changed hands and the company diversified into product lines having similar materials and processing requirements. More recently, in 2008 selected assets of Hoffman Materials, Inc, were acquired and Hoffman Materials, LLC was formed. In 2009, the company purchased the crystal growth laboratory from the University of Central Florida, and formed Krystal Engineering, LLC. In 2016, these operations were transferred to the current location in Granite Falls, NC. Since then the company has continued to diversify, with one of the most notable achievements being entry into the high temperature piezoelectric material market through growth of single crystal LGT, and parts fabricated therefrom. Our high quality products include both raw and custom processed crystalline materials for aerospace, acousto-electronic, automotive, defense, dentistry, industrial, medical and many other scientific applications. Comprised of a highly experienced staff with expertise in Czochralski crystal growth, metrology, x-ray orientation, cutting, grinding, lapping, polishing, plating, marking and packaging of crystalline materials.
