4J42 high quality Permalloy nickel strip coil welding strip

Product Description

1. Physical properties: Density: 8.12 g/cm3 Melting point: 1430 ℃ Elastic modulus: 147GPa Thermal conductivity: 12.6w /(m•℃) Hardness (HV) : 135kgf/mm2 Coefficient of thermal expansion (20-100℃) : 5.6×10-6/℃ Resistivity: 0.61 mu Ω, m 2. Main features: the expansion coefficient and Curie temperature increase with the increase of nickel content. By adjusting nickel content, soft glass with different expansion coefficients can be matched within a given temperature range. 3. Examples of application: used for sealing with soft glass and ceramics, making leads, frames and sealing plugs for electron tubes, transistors and integrated circuits.
