Wire and Cable

High-Temperature Wire

Even at 480° F—hotter than some industrial ovens—this wire’s insulation won’t melt.

High-Temperature Thin-Insulation Wire

With a slim PFA plastic insulation, this wire has the same heat resistance as standard high-temperature wire but its diameter is one-third the size for use in tight spaces.

Low-Voltage High-Temperature Wire

Rated to 50 volts AC/DC, this wire is often used in small electronics and robotics. It withstands temperatures of 390° F and greater.

High-Temperature Wire Assortments

Keep several colors of high-temperature wire on hand with these assortments.

High-Temperature Cable

For high-heat applications such as furnaces and ovens, this cable's insulation withstands temperatures of 390° F and higher.

High-Temperature Continuous-Flex Cable

Bend and flex this silicone-insulated cable in temperatures up to 350° F. It can keep moving in areas twice as hot as most other continuous-flex cables without degrading data or signal transmission.

Metal

Easy-to-Form Nickel Chromium Alloy

This nickel-chromium, often called Chromel C, provides effortless formability. Use it for heating elements, resistance windings, and hot-wire cutters.

High-Temperature 600 Nickel Wire

Able to withstand temperatures up to 1000° F, 600 nickel is often used as safety lock wire in high-temperature applications. It is comparable to Inconel 600.

High-Temperature 600 Nickel Rods

Often used in engines and heat exchangers, these 600 nickel rods can handle temperatures up to 1000° F. They also hold up to harsh chemicals and acids. 600 nickel is comparable to Inconel 600.

Multipurpose 400 Nickel Wire

Bend this wire and it will stay in place. It is often used as safety lock wire.

Ultra High-Temperature Molybdenum Wire

Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments.

Corrosion-Resistant Tungsten Wire

This wire will spring back after bending. It's often used in heating and electrical applications.

High-Temperature Nickel-Clad Copper

This copper wire is clad in nickel to provide excellent corrosion resistance at temperatures up to 1200° F while maintaining high electrical conductivity.

Tin-Coated Multipurpose 110 Copper Wire

The tin coating provides a higher level of corrosion resistance and makes it easier to solder than Mirror-Like Multipurpose 110 Copper Wire.

Mirror-Like Multipurpose 110 Copper Wire

This wire is polished to a mirror-like finish.

Ultra-High-Temperature Tantalum Wire

Harder than platinum and able to withstand higher temperatures than gold, this 99.98% pure tantalum wire also resists corrosion and conducts heat. It’s often used in heating elements for furnaces.

Platinum Wire

99.95% pure, this platinum wire is used for applications that require a soft material that resists corrosion and oxidation and has a high melting point.

Gold Wire

Used to make electrical connectors that are exposed to air and corrosive conditions, this 99.99% pure gold wire remains highly conductive where other conductors would fail.

Ultra-High-Temperature Niobium Wire

This niobium wire has a higher melting point than most other metal, so it’s also known as refractory metal. It's highly conductive, corrosion resistant, and maintains its strength even at high temperatures.
