Product Description C20Ni80 Nickel chromium alloyCr20Ni80 is a nickel-chromium alloy, also known as resistance alloy, with high resistance and high melting point. This alloy is mainly composed of 20% chromium and 80% nickel, and is usually expressed in the chemical formula as Cr20Ni80.Its main use is as a resistance wire, which is widely used in electric heaters, electric furnaces, heaters, hot air blowers, electric water heaters, water heaters, temperature sensors and other electric heating equipment. Due to the high resistance and thermal stability of Cr20Ni80 alloy, it is able to generate sufficient heat in high temperature environments, making it an ideal electric heating element.

Aerospace industry: used to manufacture high-temperature components such as engines, turbine blades, and combustion chambers. Chemical industry: used to manufacture reaction kettles, heat exchangers and other components in chemical equipment. Devices: used to manufacture devices such as artificial joints and dental implants. Other fields: such as nuclear industry, electronics industry, etc.Raw material preparation: Prepare high-purity nickel and chromium metals as the main raw materials for the alloy. These raw materials are typically available in bulk, powder or wire form and must meet strict chemical composition and purity requirements.Alloy ingredients: Nickel and chromium are mixed together according to the formula in predetermined proportions. Ensuring a homogeneous mix is key to ensuring consistent performance of the final alloy.Smelting: Put the mixed raw materials into a high-temperature smelting furnace, usually using methods such as arc melting, induction melting or gas protection melting. During the smelting process, the raw materials are melted by heating and maintained at the required component ratios and temperatures for the alloy to ensure uniform mixing.Casting or forging: The smelted alloy can be formed into a blank or preliminary shape by casting or forging. Casting is the pouring of molten alloy into a mold to form the desired shape. Forging, on the other hand, changes the shape of the alloy by heating it to the appropriate temperature and then applying pressure or impact.Heat treatment: After the alloy is initially formed, heat treatment is usually required to adjust its grain structure and mechanical properties. This may include steps such as solution treatment and aging treatments to improve the stability and strength of the alloy.Wire Drawing: Heat-treated alloy blanks may be drawn into wire. Wire drawing is the process of stretching an alloy blank through a die to the required diameter and length to make resistance wire.Final processing and testing: The drawn alloy wire may need to undergo further processing and testing, including surface treatment, fine processing, dimensional measurement and performance testing to ensure compliance with customer requirements and relevant standards.The entire production process requires strict control of process parameters and quality standards to ensure the final production of Cr20Ni80 alloy products with stable performance and reliable quality.Company ProfileFAQ How can I contact with your company?We are always ready to serve you via Email, Telephone, Fax, Skype, Whatsapp or Mobile phone.Phone:+86-13218687867 What is your working time?Monday-Saturday : 7:30AM-17:00PM (Beijing time, GMT+08.00)We have public holiday during May.1-3, Oct.1-7 and Chinese New Year holiday .
