Nickel Chrome Resistance Alloy Wire Cr20Ni80,NiCr 8020 Nichrome Wire
NiCr Series
Nichrome wire, specifically the Cr20Ni80 alloy, is highly valued for its unique properties. When heated, it exhibits a minimum electrical resistance, making it ideal for use in electrothermal equipment. Additionally, it possesses elevated temperature strength and high ductility, allowing for various forms of machining such as chiseling, welding, stamping, and drawing. The alloy also holds its shape well, adding to its durability and reliability.
Despite its high price, the performance of Nichrome wire justifies the cost. The Cr20Ni80 and Cr15Ni60 alloys are the most popular brands due to their exceptional properties. H20N80 comprises 20% chromium and 80% nickel, resulting in a resistivity of 650 Ohms/cmf and a melting temperature of 1200°C.
Overall, Nichrome wire is a versatile and reliable material that is widely used in the electrical industry. Its unique properties make it an excellent choice for heating applications and other forms of electrothermal equipment. Despite its cost, the durability and reliability of this alloy make it a worthwhile investment.
