Cr20Ni80 Alloy Wire With High Nickel Content For High Temperature Resistance

Cr20Ni80 Alloy Wire With High Nickel Content For Excellent High Temperature Resistance

Introduction:

Cr20Ni80 alloy wire is a high-temperature alloy wire, mainly composed of 20% chromium and 80% nickel. It has good high temperature resistance and can provide stable resistance characteristics in high temperature environments. This alloy wire is widely used in electric furnace heating elements, resistance welding, heaters, hot mist generators and other fields.

Mechanical behavior:

The mechanical properties of Cr20Ni80 alloy wire can be adjusted through cold working.

Cold working refers to the process of plastic deformation of alloy wire at room temperature. Common cold working methods include drawing, rolling and bending. Through cold working, the shape, size and mechanical properties of the alloy wire can be changed. Specifically:

1. Drawing: The process of drawing alloy wire through a die can reduce its cross-sectional area and increase its length. This causes the alloy wire to harden, increasing its strength and hardness but also reducing its ductility.

2. Calendering: The alloy wire is pressed through equipment such as a rolling mill to change its cross-sectional shape and size. During the calendering process, the alloy wire will undergo cold deformation, making it hard and improving strength and hardness.

3. Bending: By bending alloy wire, you can change its shape and increase its ductility. However, when bending at a large angle, it may cause breakage or surface cracks of the alloy wire.
