| Material Summary: | ||||
| Tungsten’s ability to hold its hardness at high temperature, along with its high melting point, and high conductivity makes it a great selection for a variety of applications including light bulb filaments and interconnects in integrated circuits. Its low expansion matches very well with Elan 14 glass. | ||||
