Tape alumel - 2.4122 - Nisil®

Tape alumel - 2.4122 - Nisil®

To buy at an affordable price from manufacturers a ribbon made of alumel alloy (other names — Nisil®, alloy 2.4122), offers the company AvekGlob. The supplier provides prompt delivery of products to any address specified by the consumer.

Composition and application

Alumel has the ability to function at high temperatures and mechanical loads. The alloy has good resistance against creep and oxidation. To increase the strength, solid solution hardening, strain hardening or precipitation are performed.

Tape of the magnetic alloy alumel (Nisil®, 2.4122) is widely used for the manufacture of flat thermocouples, extension cables, as well as compensating connections and jumpers. High corrosion resistance of the alloy, including high temperature resistance

The oxidized surface of the wire determines the use of the alloy in question under conditions where a corrosive atmosphere exists.

Thermocouple alloy alumel (Nisil®, 2.4122) is manufactured in accordance with the technical requirements, which are regulated by ASTM E 230 and ANSI MC 96.1 standards. After rolling, the tape is calibrated according to the temperature range in accordance with international specifications. Each coil or cassette is checked for actual EMF values, and an alternative calibration is performed at the customer’s request in accordance with the ASTM E220 comparison procedure. The limiting temperature of application of products made from this alloy is 1050 0 С.

The chemical composition of the alumel alloy (Nisil®, 2.4122) is given below:

Element Content (%)
Nickel, Ni 95
Aluminum, Al 2
Manganese, Mn 2

The presence of silicon — not more than 1.5% and carbon — up to 0.1% is allowed.

AvekGlob company offers to buy at a cost-effective price a ribbon made of alumel alloy (Nisil®, 2.4122). The supplier makes timely delivery of products to any point set by the client.
