Thermocouple alloys are the conjunction of two dissimilar metals that create a thermoelectric effect where they join. This thermal junction is sensitive to temperature variations and provides a measurable voltage change as the temperature changes.
By controlling the alloy composition of each leg of the thermocouple, you can control the response of the material.
Materials commonly associated with this application include the following.
High-temperature metals and alloys are used in many different applications and include tantalum, tungsten, graphite and other metals. Most high-temperature metals also have good corrosion resistance and, when alloyed together with other metals, are used to make “superalloys” that can be used in chemical processing plants, nuclear reactors, aerospace and similar environments. When working in high-temperature environments, you need parts you can rely on. Strength and longevity under high stress is a must.
For hundreds of years, engineers have experimented with different alloys, in an attempt to control heat expansion. In certain applications such as vacuum tubes or optoelectronics, it is necessary to adhere to set expansion requirements over specific temperature ranges.
In these cases, the following materials possess the characteristics needed.
Alloy 42
Alloy 52
Invar 36
Super Invar 32-5
Kovar
Used in applications where a hermetic seal between the metal, glass or ceramic is required, controlled expansion alloys are also used in vacuum tubes, optoelectronics, lightbulbs...
This group of metals (also called CRAs) shines in high-temperature environments where corrosion resistance, strength under pressure, and low expansion coefficients are key. CRAs are necessary in oil and gas production, jet engines, chemical plants, and some biomedical applications.
Any alloy can corrode under the right conditions. Trust our experts to help you find the best material for your project.

The metals and alloys that go into both consumer- and industrial-grade electronics must be flexible, versatile and able to be manipulated with extreme precision. Heat is another key concern with...
Refractory metals are incredibly resistant to heat and wear.
This group, also called CRAs, is typically found in high-temperature environments where corrosion resistance, strength under pressure, and low expansion coefficients are key. Oil and gas production, jet engines, chemical plants, and some biomedical applications are typical places you’ll find this category of metals.
Any alloy can corrode under the right conditions, so you’ll want to rely on our experts to help you find the best material for your project.
Soft magnetic shielding alloys are metals that can easily be magnetized. These materials have a high magnetic permeability, giving low reluctance paths for shifting magnetic fields.
These properties make soft magnetic shield alloys great shields against static and slowly varying magnetic fields. They’re often used to improve quality in home theaters and to shield sensitive medical and electronic equipment.
Materials included in the soft magnetic shield alloy group include the following.
