Today, more and more design engineers are substituting Fusite's copper core wire for solid wire because of the company's proven hermetic metallurgical bond and its compatibility with many sealing glasses.

The copper core permits a conductor of smaller diameter than solid wire to be used for a given power requirement. In addition, it maintains excellent mechanical strength and ductility. Various alloys and copper core ratios are available with electrical resistivity (@68°F) ranging from 42-76 ohms-cir. mil./ft.). Diameters as small as .010" to over .500" are produced on a regular basis. Fusite's oven and custom glass formulation capabilities allow for fusing or brazing a variety of different metals and alloys.

Pin/Tube Materials

• Copper Cored Stainless Steel Cold Rolled Steel (1010 or 1008)
• 52 Alloy
• 42 Alloy
