5 Description AMETEK s 899 Series Is an extremely high-purity strip that can be formed welded, soldered, or plated better than traditional melt or cast nickel products, offering major advantages to the rechargable battery industry. AMETEK high-purity 936, 942, 946, 948, 952 alloys for glass to metal seals in electron tubes, transistors, headlights, thermostats, and similar applications. Other nickel/iron variations can be made at the customer s request. SEALVAR (Alloy F-15), AMETEK s nickel iron cobalt strip, is a high quality alloy used primarily for hermetic seals with harder glasses and ceramics (lids for hybrid packages). SEALVAR is distinguished from competitive F-15 alloy used by its higher purity, more closely controlled chemistry, and very low carbon level. Ideal for superconducting tape substrate applications. Ductile cobalt in strip form is used for base welding rods and deep draw applications. It also is used as a catalyst for synthetic diamond production. AMETEK 599 is the highest purity cobalt strip available in the United States. Applications include cobalt 60 gamma radiation sources, anodes for electroplating, high-temperature magnetic applications, and X-ray tube targets. Large oscillating reels (up to 480 lbs.) used by weld wire producers in place of smaller pancake coils. Roughly 7 coils per reel. Standard size range is to thick by wide. AMETEK 377 PFINODAL (C729) competes with beryllium-copper for many electrical applications where high strength and excellent formability without dimensional instability are required. AMETEK 388 Spinodal (C72650) offers high conductivity and strength for connectors, sockets, bearings, and switches. Developed for high-temperature applications. AMETEK 900B (low carbon) strip for magnetic applications. Advantages Highest degree of electrical conductivity Lowest electrical resistivity available in pure nickel strip Homogeneity, microcleanliness, and close composition control to enhance weldability Low levels of surface oxides to reduce die wear and provide excellent solderability Excellent formability Controlled chemistry ensures superior glass sealing characteristics Thermal expansion and magnetic properties are consistent Low levels of surface oxides reduce die wear Low gas content reduces possibility of out gassing over time Reproducibly low level of reactive impurity elements Low carbon; 0.01% maximum; nominal Higher electrical and thermal conductivity Lower softening point Reducing magnetism Currently up to 25% tungsten Other nickel tungsten blends available Excellent ductility and formability Ductile strip has more than double the elongation value of high-purity cobalt strip Cost savings from using smaller pancake coils. High strength and excellent formability without dimensional instability Highly resistant to shrinkage and warpage- up to 10x more than BeCu Excellent solderability and resistance to intermetallic formation at high temperature Excellent corrosion resistance and ease of cleaning Lower initial cost and processing cost savings High conductivity (Spinodal 388) High hardness Excellent oxidation resistance Good high-temperature creep resistance Low density (6gm/cc) Low carbon (<100ppm) Very high purity 2
