supplies a wide range of
resistance type wires for the repair and manufacture of
filaments and heaters for mass spectrometers, SEM's and
scientific instruments. Wires are often used for these applications
such as rhenium, tungsten, platinum, and tantalum .
Thermocouple wires, such as chromel, constantan, alumel, and
iron can be used to manufacture your own thermocouples. In
addition, we supply a wide range of high purity wires including gold,
silver and platinum for a wide range of uses including gasket
fabrication and sputter coating. In addition to the wires listed
below, we can obtain other sizes and types. Call with your
specifications for a price quotation.
Quantity discounts - 10% discount on quantities of 10 or more feet with the exception of
gold, silver, and platinum.
