What is nickel-chromium alloy

Introduction to nickel chrome alloy

Chromium alloys have high strength and corrosion resistance, and alloys composed of iron and nickel are commonly known as stainless steel.  Nickel chromium is two metal elements, both can be alloyed with iron, aluminum, silicon, carbon, sulfur and other impurities into nickel chromium wire.  Nickel - chromium wire has high resistivity and heat resistance, is electric furnace, electric soldering iron, iron and other electric heating elements.  High resistance electrothermal alloy (high nickel and iron chromium aluminum), high temperature alloy, precision alloy, heat resistant alloy, special alloy, stainless steel are common and commonly used nickel-chromium alloy.  

Simple classification of nickel chrome alloy

Nickel-chromium wire can be divided into nickel-chromium round wire, nickel-chromium flat wire, nickel-chromium strip, etc.  

Usage of nickel chrome alloy

Nickel-chromium alloy corrosion resistance, low price, is China's most porcelain dental crown, medical nickel-chromium alloy, mainly nickel, chromium and a small amount of other metal elements harmless to human body, the adverse effect of nickel-chromium alloy on human body is mainly caused by nickel.  

Can be used as a laboratory resistor.  

In the alcohol detector used by the traffic police, the chromogenic substance is dichromate, with which alcohol can act to make it chromogenic.  

Potassium dichromate and sodium dichromate are strong oxidants in organic synthesis and petroleum industry. Chromium yellow, chromium orange and chromium green can be used as inorganic pigments.  

Ni-Cr alloy is also widely used in vacuum coating industry, which can be made into a certain proportion of alloy targets and raw materials for magnetron sputtering coating.  

High resistance electrothermal alloy (high nickel and iron chromium aluminum), high temperature alloy, precision alloy, heat resistant alloy, special alloy, stainless steel are common and commonly used nickel-chromium alloy.  

Characteristics of nickel chromium alloy electric furnace wire

High strength at high temperature  

After long-term use and then cool down, the material will not become brittle 

The emissivity of fully oxidized Ni-Cr alloy is higher than that of Fe-Cr alloy  

There is no magnetic  

Good corrosion resistance except sulfur gas  

Nickel chromium wire and ferrochrome aluminum wire are called electric heating wire because they belong to electric heating resistance alloy, used as electric heating element, or heating element, also called resistance wire, because it is often used as resistance element. 

Nickel-chromium wire has high resistivity, good surface oxidation resistance, high temperature level, and has high strength at high temperature, has good processing performance and weldability, can be widely used in metallurgy, household appliances, machinery manufacturing and other heating elements and electrical industry as resistance materials.  Long service life, but because of nickel, so the price is higher.
