nickel silver ns108

Product Details

Nickel silver, also known as cupronickel, is a popular alloy used in various industries due to its unique combination of properties. NS108 is a specific grade of nickel silver that offers excellent corrosion resistance, high strength, and good ductility. In this article, we will delve into the properties and applications of nickel silver NS108, as well as explore its chemical, mechanical, and physical properties.
Chemical Properties of Nickel Silver NS108
Nickel silver NS108 is an alloy composed of copper, nickel, and zinc. The chemical composition of NS108 is as follows:
- Copper (Cu): 55-58%- Nickel (Ni): 18-20%- Zinc (Zn): 24-27%- Lead (Pb): 0.5-1.5%- Iron (Fe): 0.5-1.5%
The addition of nickel to copper improves the alloy's corrosion resistance, particularly in marine environments. The zinc content enhances the alloy's strength and ductility.
Mechanical Properties of Nickel Silver NS108
The mechanical properties of nickel silver NS108 are as follows:
- Tensile strength: 700-800 MPa (101,500-116,000 psi)- Yield strength: 350-450 MPa (50,750-65,250 psi)- Elongation at break: 20-30%- Hardness: 160-180 HV (Vickers hardness)
The high tensile strength and yield strength of NS108 make it an ideal material for applications that require high strength and resistance to deformation.
Physical Properties of Nickel Silver NS108
The physical properties of nickel silver NS108 are as follows:
- Density: 9.2-9.4 g/cm³- Melting point: 1,050-1,100°C (1,922-2,012°F)- Electrical conductivity: 10-15% IACS (International Annealed Copper Standard)- Thermal conductivity: 50-60 W/mK
The high density of NS108 makes it suitable for applications that require high weight-to-strength ratios.
Applications of Nickel Silver NS108
Nickel silver NS108 is used in various industries due to its unique combination of properties. Some of the common applications of NS108 include:
- Electrical components: NS108 is used in electrical components such as switches, contacts, and connectors due to its high electrical conductivity and corrosion resistance.- Marine hardware: NS108 is used in marine hardware such as propeller shafts, fittings, and fasteners due to its high corrosion resistance and strength.- Aerospace: NS108 is used in aerospace applications such as aircraft fittings, fasteners, and hardware due to its high strength-to-weight ratio and corrosion resistance.- Musical instruments: NS108 is used in musical instruments such as trumpets, trombones, and French horns due to its high corrosion resistance and ductility.
Other Grades of Nickel Silver
In addition to NS108, there are several other grades of nickel silver that offer different combinations of properties. Some of the other grades of nickel silver include:
- NS102: This grade of nickel silver has a higher copper content than NS108, which makes it more ductile and less strong.- NS104: This grade of nickel silver has a higher nickel content than NS108, which makes it more corrosion-resistant and less ductile.- NS105: This grade of nickel silver has a higher zinc content than NS108, which makes it more strong and less corrosion-resistant.- NS106: This grade of nickel silver has a higher lead content than NS108, which makes it more machinable and less strong.
