Supplier guaranteed timely delivery at any address specified by the consumer. Regular customers can take advantage of the discount system of discounts from the company KMZ.

Chromel

Chromel contains 90% Nickel and 10% chromium. It is used in the manufacture of the positive ends of thermocouples and other devices to measure temperature. This alloy can withstand a wide range of temperatures (-452 ° C to 1100 ° C) and in oxidizing environments.

Alumel

Alumel: magnetic alloy which consists of Nickel (95%), manganese (2%), aluminium (2%) and silicon (1%). This alloy provides stable specific resistance and thermal conductivity. Alumel is used as extension wire for thermocouples.

Constantan

Constantan: an alloy composed of 55% copper and 45% Nickel. Its advantage is the constant resistance in a wide range of temperatures. The alloy used in the manufacture of thermocouples, along with iron, copper, chromel and alumel.

Kopel

Kopel: copper-Nickel alloy, which contains about 43% Nickel and about 0.5% manganese. Composition and properties similar to Constantan but has a different peak, and thermopower, which provides the highest efficiency of its use in thermocouples.
