7059 barium-borosilicate glass is an almost alkali-free flat glass from Corning that features a good thermal shock resistance. It has long been a standard of the electronics industry for thin-film circuits, which require special electrical mechanical and thermal properties. 7059F glass is fusion drawn into sheets to final thickness, obtaining a flat, smooth surface finish directly from the molten glass. 7059 however, is slot drawn and is not as flat as the 7059F, which is fusion drawn. Both 7059 glass materials have a low level of alkali which is less than 0,3 %. This is important for many electronic applications, because alkali ions are known to lower the performance, reliability and longevity of thin-film devices.

Note: The production of 7059 and 7059F has been discontinued a long time ago. We still stock some remaining 7059 (non-F) material at 0,7mm thickness though. The direct follow-up glass materials are 1737F from Corning.
