Description
Resistance wire is an electric heating alloy which makes use of the resistance characteristic of material to produce heating element. There are two main categories: one is ferrochrome aluminum alloy with ferrite structure; The other is nickel-chromium alloy with austenitic structure. These two kinds of electrothermal alloys have different properties as their different structure. As electric heating materials, they each have more advantages, so get a large number of production and wide use in various countries.
Electric furnace resistance wire for furnace use high quality fe-Cr-al, ni-Cr-electrothermal alloy wire as raw material, the furnace wire power is controlled by computer, and the resistance wire is wound by high-speed automatic winding machine. This product is characterized by high temperature resistance, fast temperature rise, long service life, stable resistance, small power deviation, even pitch after stretching, bright and clean surface, widely used in small electric furnace, muffle furnace, heating and air conditioning equipment, all kinds of ovens, electric heating tubes and household appliances.
Nickel-chromium alloy wire has a relatively high resistivity, which means they can effectively generate heat when current passes through them.These alloys can withstand high temperatures without significant performance degradation and are suitable for heating applications that require continuous high temperatures.Nickel-chromium-based resistance heating alloys suitable for element temperatures up to 1250°C (2282°F). Ni-Cr resistance heating alloys are characterized by very good mechanical properties in the hot state as well as good oxidation and corrosion properties.It has anti-oxidation and anti-corrosion properties at high temperatures, which can extend their service life in harsh environments.
Electric furnace resistance wire for furnace based on iron-chromium-aluminium for maximum element temperature of 1425°C (2600 °F). resistance heating alloys are characterized by high resistivity and capability to withstand high surface load.NiCr resistance heating alloys
Our company sells iron-chromium-aluminum heating wire and nickel-chromium heating wire. Many customers often inquire about a simple way to identify whether the material is actually nickel-chromium or iron-chromium-aluminum. Therefore, below points are the method for all our new and old customers:
The method for distinguishing
1. Soak them in salt water. The ones that get rusted are the iron-chromium-aluminum wire.
2. FeCral heating wire undergoes severe oxidation very quickly and becomes thinner, eventually getting damaged. Nickel wire has a longer lifespan.
3. The high-temperature strength of iron-chromium-aluminum wire is low. As the operating temperature increases, its plasticity increases, and the components are prone to deformation and difficult to repair. However, nickel-chromium is different.
