Introduction
Where reliability in hostile heat conditions is a must, Nickel-Based Alloys are the unseen drivers of thermal measurement and heating solutions. Tempsens’ superior line of nickel alloys and thermocouple conductors is specifically designed to deliver in the most challenging industrial applications—ranging from blast furnaces and reactors to cleanrooms and resistance heating configurations.
As opposed to generic alloy suppliers, Tempsens brings decades of metallurgical experience, state-of-the-art in-house wire processing, and specialty manufacturing to fulfill worldwide thermocouple and heater requirements. Each conductor—bar, rod, or wire—is processed and tested in NABL-certified laboratories to national and international standards of thermal and electrical performance.
About Nickel-Based Alloys
Types of Nickel Alloys
- Pure Nickel (Ni200/201):
This is the cleanest form of nickel we work with—highly ductile, corrosion-resistant, and perfect when you need reliable electrical conductivity in demanding environments
- Nichrome (NiCr 80:20, 70:30)
High-resistance heat alloy commonly used in electric furnaces and heaters because of its oxidation resistance and stability.
- Copper-Nickel (CuNi 95:5, 90:10, 70:30):
Provides higher corrosion resistance in chemical and marine environments, typically found in heating mats and piping.
- Thermocouple Alloys (Types K, J, T, N, E):
Nickel alloys with applications to accurate temperature measurement in industrial thermocouples.
- Extension & Compensating Alloys:
Nickel alloy types for extending thermocouple
signals without loss of accuracy and thermal EMF stability.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Nickel-Based Alloys.
A Type C thermocouple has a positive leg made of Tungsten with 5% rhenium and a negative leg made of Tungsten with 26% rhenium. Both legs are suited for use in vacuum or inert atmospheres, and can function at temperatures up to 2315°C.
A Type K thermocouple’s positive leg is composed of Chromel (90% Nickel and 10% Chromium). The negative leg is made of Alumel (approximately 95% Nickel with Aluminium, Manganese and Silicon) and can be utilized between -200°C and +1260°C.
Nichrome 80:20 is used extensively for heaters due to its high-temperature strength, electrical resistance, and stability.
Nickel alloys are applied in heaters, thermocouples, aerospace, chemical industry, and marine environments for their resistance to heat and corrosion.
