What is Alumel®?

 

Alumel® is a nickel alloy.

 

Properties and Appearance

Alumel® is a nickel, aluminum, manganese, and silicon alloy and is a somewhat dull gray metal. It belongs to the thermocouple alloy group.

Alumel® is magnetic and has good electrical resistivity and thermal conductivity, making it ideal for use in thermocouples and as thermocouple extension wire. When combined with Chromel®, Alumel® is the negative leg of a Type K thermocouple.

With its magnetic properties, electrical resistivity, and thermal conductivity, Alumel® is valuable to the aerospace, medical, and nuclear industries, among many others.

Kovar Alloy Supply by Vulcan Metal Group

Image
  Kovar is a specific type of alloy known for its low coefficient of thermal expansion (CTE), making it particularly useful in applications where dimensional stability over a range of temperatures is crucial. Kovar is an iron-nickel-cobalt alloy with controlled expansion characteristics. Its chemical composition typically includes: Iron (Fe): Around 54% Nickel (Ni): Around 29% Cobalt (Co): Around 17% Trace amounts of other elements such as manganese, silicon, and carbon. The name "Kovar" is derived from the first syllables of the main components—Ko for cobalt, Va for iron, and R for the Russian scientist Boris Vasilievich Romanov, who was involved in its development. Key characteristics and applications of Kovar alloy include: Low Coefficient of Thermal Expansion (CTE): Kovar is designed to exhibit a low CTE, meaning that it expands or contracts very little with changes in temperature. This property is crucial in applications where dimensional stability is essential, partic...

Four Things to Know About Molybdenum Before You Source Parts

Image
  For a number of applications in aerospace, defense, energy, and medical diagnostics, molybdenum offers an ideal combination of high performance and practicality. Key characteristics include: A melting point of 4753°F (2620°C) and a peak working temperature of about 3565°F (1965°C) Excellent material strength at high temperatures: tensile strength of about 14,000 psi at 2200°F (1200°C), for example. High thermal conductivity: can be quenched from very high temperatures without cracking Low vapor pressure: minimal outgassing even in hard vacuum Low coefficient of thermal expansion (CTE): exceptional dimensional stability for applications involving temperature swings Corrosion resistant: good for harsh environments These properties combine to make molybdenum a good fit for high temperatures, hard vacuums, and applications requiring strong, lightweight metals.  The trade-off is that molybdenum has several pitfalls that can trap the unwary. Let’s take a look at what you need to ...
