Specialty Wire
WPI offers a variety of precious metals and wire.
The table below compares the specifications of the various wires. The following hints are offered to help you understand the part number codes and choose the wire you need:
- Micro coaxial cables (MAXxxxx) are ideal for microelectrode fabrication and construction of similar research tools. The dual shielding eliminates electrical interference caused by radio frequencies (RF), electrostatic and microphonics (e.g., bending and vibration). Available with single or dual (twin) conductors.
- Thermocouple wire is for temperature monitoring. TCK3050 has a chromel/alumel pair, for use in inert or oxidizing atmosphere at 1500-1800 °F.
- Teflon-coated stainless steel (type 304) wire (SSTxxxx) is available in 25-ft and 50-ft lengths. The Teflon coating is 4µm thick.
- Carbon wire (C3005) is a single 30µm fiber of electrochemically activated carbon. This fiber is especially useful in micro-electrochemical experiments.
- Carbon filament wire (CPVCxxxx) is made of 3,000 microscopic carbon strands in a colored PVC jacket. 45.8 ohms/foot.
- Copper ultra-fine wire (CU7T44G) is made of seven individually insulated 44 AWG (50µm) conductors twisted together. Total diameter with insulation is 200µm. Resistance: 2.9Ω/m for all seven wires together. Dry dielectric strength: 1500V DC.
- Platinum/iridium wire — uncoated (PTxxxx) and Teflon-coated (PTTxxxx) — is an alloy of 90% platinum and 10% iridium, giving excellent tensile strength and corrosion resistance. Uncoated pure platinum wire (PTPxxx) is 99.95% pure.
- Indium wire (IN1003) is 99.99% pure, with a melting point of 156.4°C.
- Annealed silver wire (AGWxxxx), 99.99% pure, is available in five diameters; three of those sizes are also available with a Teflon coating (AGTxxxx).
- Tungsten wire (TGWxxxx), available in three diameters, is 99.95% pure.
-Gold wire (AUWxxxx) is 99.99% pure.
- Stainless steel wire (SSxxxxx) is type 316.
