Cr20Ni80 Wire NiCr Alloy Widely Used In Heat Treating Ceramics
Glass And More
Product Description:
NiCr alloy, including Cr20Ni80, are valued for their excellent heat
generation, oxidation resistance, and high-temperature performance.
These properties make them reliable and efficient heating elements
in heat treating 
ceramics and glass applications. Here's how NiCr alloy is used in heat treating ceramics and glass:
1. Electric Kilns and Furnaces: NiCr alloy is commonly employed as
heating elements in electric kilns and furnaces for ceramic and
glass production. The alloys' high melting point and oxidation
resistance enable them to withstand the high temperatures required
for these processes. NiCr heating elements provide controlled and
uniform heating, allowing for the shaping, glazing, and firing of
ceramics and glass materials.
2. Annealing and Tempering: NiCr alloy is utilized in heat
treatment processes like annealing and tempering to enhance the
structural properties of ceramics and glass. These alloys serve as
heating elements to provide the necessary heat for controlled
cooling and annealing cycles. This helps relieve internal stresses
and improve the strength and durability of the materials.
NiCr (nickel-chromium) alloys, including Cr20Ni80 (Nichrome 80/20),
are indeed widely used in heat treating ceramics and glass
applications. These alloys possess excellent electrical resistance
and high-temperature stability, making them suitable for various
heat treatment processes.
