4J29 Kovar Alloy Pipe FeNi Glass Sealing Vacon 12 For

4J29 also known as Kovar alloy. it was invented to meet the need for a reliable glass-to-metal seal, which is required in electronic devices such as light bulbs, vacuum tubes, cathode ray tubes, and in vacuum systems in chemistry and other scientific research. Most metals cannot seal to glass because their coefficient of thermal expansion is not the same as glass, so as the joint cools after fabrication the stresses due to the differential expansion rates of the glass China 4J29 Kovar Low Expanding Alloy Ni29Co18 for Glass China 4J29 Kovar Low Expanding Alloy Ni29Co18 for Glass Sealing, Find details about China Kovar, glass seal from 4J29 Kovar Low Expanding Alloy Ni29Co18 for Glass Sealing - Jiangsu ToLand Alloy
