Alloys have been used in industries for a long time. Few widely used applications are:

 High temperature alloys have been used for many aerospace and petrochemical applications. In addition, they have been used for welding wire, where elevated temperatures and harsh environments are routinely encountered. These alloys have been used in applications where corrosion resistance and high strength must be maintained at elevated temperatures.

Alloys are also used to produce internal and external leads.

Nickel-Chromium, Nickel-Chromium-Iron, and Iron-Chromium-Aluminum alloys have been used for high-temperature heating elements. Nexteck Technology is an prominent supplier for Nickel-Chromium, Nickel-Chromium-Iron, and Iron-Chromium-Aluminum alloys products.

Some alloys are used as resistance elements to control or measure electric current. Applications have included wire-wound resistors, rheostats, potentiometers, and shunts.

Thermocouple alloys have found a wide-range of use in temperature sensing and control. Nexteck Technology's thermal alloy products includes types N, K, J, T, E, L & U.

Alloys are also used as thermostat metals, radio and electronic devices, precision devises in aircraft controls, telecommunications, automotive applications, and more.

Some alloys function as corrosion-resistant materials and are used in moisture rich-environments.

Magnetic alloys are used for magnetic cores and dry reed switches. Quality control measures include magnetic testing to maintain consistently high standards of uniformity and performance.

Alloys of Gold and Silver are used in the preparation of jewelry. White Gold, which is an alloy of Gold, Silver, Palladium, and Nickel is used as cheap alternative of Platinum. A wide selection of alloys is used in welding applications by numerous industries.
