Iron - Import export

At AMETEK Specialty Metal Products we produce high purity nickel-iron alloy strips, which are primarily used for reed switch systems. These products are widely used in the automotive market for BMS (Battery Management Systems), improved safety in proximity sensors, and cable harness testing. Alloys Our strips are produced using nickel-iron compositions, making sure to use source metals with market leading low levels of trace elements. Alloys include: Nickel-Iron compositions from 36% to 65% Nickel. Sizes Strip thicknesses down to 0.002” (0.0508mm) and wire diameters as small as 0.005” (0.127mm). Applications Finished nickel-iron alloy reed switch systems are used within a multitude of products and devices, mainly being used in the Automotive and Electronics industries. Automotive: BMS (Battery Management Systems), automatic braking assists, door sensors and speedometers.

Our weld wire sheathing material is used in both flux cored wire and metal cored welding wire processes. The wire sheathing is formed into a tubular product by our customers and the center of the tube contains the ‘fill’ (flux, metal powders, etc) to bring the wire to the desired chemistry. The finished wire is used across a wide breadth of industries in processes such as: Submerged Arc Welding (SMAW) Gas Metal Arc Welding (GMAW) Wire Arc Thermal Spray Flux cored welding wire producers use our metal sheathing materials to prepare finished wire for thermal spray and in surfacing applications, in high temperature and corrosive environments. Cobalt Our Ductile Cobalt Alloys are used to produce wire to hardface applications in the construction, mining, and oil and gas industry. Our proprietary process allows us to offer high Cobalt containing products (91% Cobalt or more) while maintaining a highly ductile strip for wire forming.

Our High Purity Iron is generally used as a header material for Hermetic Package applications. The material is characterized by the extremely low carbon content (below 100ppm). Additional applications are as a catalyst for synthetic diamond production.

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.

Our Nickel-Iron-Cobalt alloys are engineered to ASTM F15 standards for sealing materials and their specified coefficients of thermal expansion. These materials used primarily for making hermetic seals with harder glasses and ceramics (lids for hybrid packages). Nickel-Iron-Cobalt alloys include F-15 alloy, Kovar ® and Rodar ®. The low levels of impurities in the material reduce the chance of out-gassing over time; a critical role in maintaining the hermetic seal.

Precision C is a heat treatable Nickel-Iron Alloy used in critical diaphragm applications, such as, metal diaphragms for aerospace sensors and burst discs. The alloy composition provides a unique constant elastic modulus value over a temperature range of -50ºF to 150ºF. Precision C can be readily formed from the annealed temper. It has a work hardening rate similar to austenitic stainless steel. The material can be joined by TIG, EB, and resistance welding as well as by brazing and soft solder technique. The heat treatment of Precision C can be adjusted to produce the desired value for the thermoelastic coefficient at or near zero. The elevated strength in the heat treated temper results in low mechanical hysteresis and low drift. Available Sizes: Precision C is available from Hamilton Precision Metals as strip product in thickness from 0.0005” to 0.040” (0.0127 mm to 1.016 mm) and widths up to 8.0” (203.2 mm). The material conforms to ASM 5221 and UNS N09902.
