Brazing and Glass-to-Metal Sealing Jigs Sealing Jigs for Brazing and Glass-to-Metal Made of RINGSDORFF® Graphite Graphite jigs are used in the production of semiconductor encapsulations by glass-to-metal sealing or brazing connections. The greatest precision is needed in machining these parts. The graphite grades used must exhibit low abrasion, high edge strength and particularly high resistance to oxidation and carbonizing. SGL Group has developed suitable materials to match these requirements: Uniform heat distribution Electrical resistivity adjusted to the current supply, to ensure correct heating High abrasion resistance
