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.

Rodar® is an Iron-Nickel-Cobalt alloy with an unique linear thermal expansion coefficient. It is also stable to cryogenic temperatures. This combination of characteristics has prompted its application in electrical package sealing of glass/metal and ceramic/metal. Rodar® can be formed and deep drawn from the annealed temper. A 1/8 hard temper is optimum for heavy piercing.The material can be joined to other metals by welding, brazing, and soldering. The joint design must consider that Rodar® has a lower expansion coefficient than most other metals. Available Sizes: Rodar® is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.060” (0.0254 mm to 1.524 mm) and width up to 12.0” (304.8 mm). The material conforms to ASTM F15, AMS 7728 and UNS K94610.

Our Nickel-Iron alloys are engineered to the ASTM F30 standards for sealing materials and their specified coefficients of thermal expansion. These materials are generally used as the sealing material to bridge the difference between two materials of differing expansion rates during heating and to maintain a hermetic seal. These Nickel-Iron Strip Products are generally used in glass to metal sealing applications ranging from light bulbs to hermetically sealed integrated circuits as well as electrical applications such as switch-gear connections and reed switch systems. Nickel Iron alloys include Invar®, alloys 42, 46, 48 and 52. Others available on request.

As a leading metal wire manufacturer, we engineer high tolerance custom shaped wire and flat wire products in a wide range of standard shapes in addition to custom shapes. The range of alloys available is nearly endless with choices from our own high purity wrought powder metallurgy alloys (nickel wire, Pfinodal® wire, Sealvar®, and Nickel Irons). We also process materials from nearly any metal wire manufacturer or rod producer on the planet including stainless wire, steel wire, aluminium wire and more. A comprehensive review of these materials can be found in our Shaped Wire Brochure Standard Shaped Wire Standard shaped wire is available from on-site tooling in round, square, and flat wire products. Edges of flat wire products can be profiled with square, rolled rounded edges, natural round edges or fully blended round edges. Applications for standard shaped wire include
