Nickel 80% Chromium 20% Nicr Alloy Wire For Plastic Bag Sealing Industry
1. Detailed Description
Nichrome is basically a name given to nickel-chromium resistance wires. It is a non-magnetic alloy, which consists of 80 percent nickel and 20 percent chromium by weight, and is widely used in heating elements because of its relatively high resistivity. Out of the constituents of nichrome, nickel is an element with the chemical symbol Ni and atomic number 28, whereas chromium is an element with the symbol Cr and atomic number 24. Nickel is generally a silvery-white lustrous metal, and chromium, a steely-gray and hard metal. Nichrome, the alloy, is silvery-gray in color, resistant towards corrosion, and has a high melting point.
Physical Properties of Nichrome
The ultimate tensile strength of nichrome is 105,000 PSI (Pounds per Square Inch) and yield strength is around 50,000 PSI. Following are some of the other physical properties of nichrome.
· Electrical Resistivity at room temperature: 1.0 x 10-6 to 1.5 x 10-6 ohm m
· Thermal Conductivity: 11.3 W/moC
· Magnetic Attraction: None
· Thermal Expansion Coefficient (20oC to 100oC): 13.4 x 10-6/oC
· Temperature Coefficient of Resistivity (25oC to 100oC): 100 ppm/oC
· Specific Gravity: 8.4
· Density: 8400 kg/m3
· Melting point: 1400oC
· Specific Heat: 450 J/kgoC
· Modulus of elasticity: 2.2 x 1011
