Wire and Cable

High-Temperature Wire

Use this wire in ovens, furnaces, and other electrical heating equipment where temperatures reach 480° F and higher.

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 Cable

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

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

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.

Multipurpose 400 Nickel Wire

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

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.

Mirror-Like Multipurpose 110 Copper Wire

This wire is polished to a mirror-like finish.

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.

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.

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.

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.
