HPM ® 270 Nickel is the highest purity Nickel. The controlled low impurity level provides uniform and repeatable mechanical, electrical, and magnetic properties. The material has excellent corrosion resistance with high thermal and electrical conductivities. A high thermal coefficient of electrical resistance makes it suitable for strain gauges, temperature sensors, and electronic components. The alloy can be formed by all conventional cold forming methods, and can be joined by resistance welding, brazing and soldering. The corrosion resistance is generally very good in most mediums, although, it is subject to intergranular embrittlement by sulfur compounds above 315°C Available Sizes: HPM ® 270 Nickel is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.020” (0.0127 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). It is available as foil as thin

Moly Permalloy® is a Nickel-Iron-Molybdenum alloy with a magnetic permeability that makes it suitable for electrical shielding applications. The alloy can be readily formed from the annealed temper.Effective magnetic shielding is provided by annealing at 1900°F or higher. Joining is accomplished by spot welding or tungsten inert gas welding. Available Sizes: Moly Permalloy® is available from Hamilton Precision Metals as strip product from 0.0005” to 0.015” (0.0127 mm to 0.38 mm) in widths to 12.0” (304.8 mm). It is also available in foil as thin as 0.000100” (0.00254 mm) in widths of 4.0” (101.6 mm) maximum. The metal conforms to ASTM A753, Type 4 and MIL N 14411, Type 1.

Our ability to strategically blend alloys allows us to offer specifically blended materials such as highly alloyed Nickel-Tungsten strip (NiW) for superconducting substrates. These custom alloys are available at customer-specified chemistries and cold work. The use of Tungsten in these alloys produces a flexible strip with preferred magnetic characteristics for superconducting wire. High Temperature Superconductors Our Nickel Tungsten substrate material is used in high temperature superconductors (HTS) to carry high-density electrical currents with very little energy dissipation. This property makes high temperature superconducting wire suitable for sectors such as power generation and transmission, electric motors, and high magnetic field generation. Nickel and nickel alloys are used as substrate materials because they are flexible to the thermomechanical processing of the wire making process.
