Detailed explanation of the types, applications and characteristics of nickel-chromium alloy wire mesh
Nickel-chromium alloy wire mesh is also known as nickel-chromium alloy filter mesh, nickel-chromium alloy woven mesh, nickel-chromium alloy screen, and nickel-chromium alloy mesh belt.
The main chemical components of nickel-chromium alloy wire are nickel and chromium. Because it contains 79% nickel, it has strong corrosion resistance. Because it contains 20% chromium, it has high strength.
The main specifications of nickel-chromium alloy wire mesh:
Due to the chemical composition and physical properties of nickel-chromium alloy wire mesh, the finest nickel-chromium alloy wire can be drawn to a diameter of 0.06mm, so the most dense specifications of nickel-chromium alloy wire mesh can be produced to 200 meshes, with a mesh size of 0.08mm. Special meshes can be customized.
Nickel-chromium alloy wire mesh is a special alloy wire mesh that is resistant to high temperature and corrosion. The main chemical elements are nickel and chromium. The series of materials of nickel-chromium alloy wire mesh are: Cr20Ni80, Cr30Ni70, Cr15Ni60, Cr20Ni35, Cr20Ni30.
Features: It has excellent elongation, compressive strength, surface finish, oxidation resistance, sulfur resistance, and permeability resistance. It has many repeated bending times, stable resistance and temperature coefficient, high allowable surface load, light specific gravity and economical and reasonable price. High strength and corrosion resistance, high resistance electric heating alloys (high nickel and iron-chromium-aluminum), high temperature alloys, precision alloys, heat-resistant alloys, special alloys, stainless steel, etc. are common and commonly used nickel-chromium alloys.
Uses: Widely used in aerospace, shipbuilding, military, chemical machinery, electric power, seawater desalination, medical equipment and other fields, playing an important role in the development of the national economy.
