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 0.007” to 0.020” thick by 0.900” 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.
