Specialty magnetic and non-magnetic alloys for GMR/TMR/CPP heads, LMR/PMR media, and MRAM technology are produced in a wide array of shapes and sizes meeting the requirements of virtually all deposition equipment. Targets are produced via vacuum induction melting or with our advanced Hybrid™ processing techniques. Materials are highly characterized in our analytical lab. Special attention is paid to grain size, homogeneity, gaseous and metallic impurities, pass through flux, as well as bulk compositional tolerances.
Williams has earned a position as a leading sputtering target supplier to the HDD market. We are the largest supplier to the thin film recording head market. Williams stands together with TFH makers in developing new materials enabling next generation GMR, TMR and CPP thin film heads. Our Xtended Life™ target designs, metallurgical product improvements, and cost of ownership solutions continue to assist TFH makers increase areal density while lowering overall costs.
Williams has extended its scope and product development into the magnetic media segment of the HDD market. With the unique capabilities of in house precious metal manufacturing and refining services, Williams now offers the magnetic media market a fully integrated source for magnetic media sputtering targets. Williams supports present day longitudinal magnetic recording (LMR) and future perpendicular magnetic recording (PMR) formats with precious and non-precious metal sputtering targets and precious metal management programs.
By maintaining a fully integrated facility, Williams is able to provide industry leading lead times and cycle times on a worldwide basis. We maintain a full staff of metallurgists and applications engineers at our manufacturing facilities as well as support personnel in key locations around the globe.
