Tubular Side Wall Frames for hybrid microelectronics applications. Various Nickel Iron alloys and other materials available. A wide range of open tooling for quick delivery available.

For over 25 years, A.T. Wall Company has been a leading producer of tubular side wall frames for hybrid microelectronic circuit packages used in defense, commercial electronics, and medical applications worldwide. These tubular frames serve as sidewalls for hermetically sealed flat packs that demand restrictive dimensional tolerance and precise metallurgical qualities.

The Warwick plant utilizes a unique manufacturing process involving hydraulic press forming of nickel alloy plate circles into cups, followed by traditional tube annealing, cold drawing, and cutting to size. A.T. Wall is currently the only sidewall frames manufacturer capable of producing Kovar tubular frames through this process.

In addition, a number of secondary operations are offered, including lap grinding and sidewall hole piercing.

If you require production quantities, you'll find that A.T. Wall is the undisputed leader when it comes to a broad selection of sizes, shapes, and materials... delivered fast.

Specialty cold drawn tubing for all tube required applications. An endless variety of materials sizes and shapes available, including aluminum, brass, bronze, stainless steel, monel, cupro-nickel, and low-carbon steel.

The General Engineered Tube serves as the development resource for new and future products in conventional and unusual alloys. A.T. Wall's Special Tubing Products are often the only source of supply for many customers. This group has earned a reputation for providing both traditional and special tubular shapes finished as random or straight length cuts ... where specifications are unusually restrictive ... and often, in alloys that make manufacturing impossible for other vendors. A unique hydraulic press-forming manufacturing process allows the production of tubing products in a wide range of metals, including unusual alloys ... which are normally not available in tubular form.

The combination of these specialized capabilities in this area have made this group a one-source supplier for companies with a variety of diverse applications in the medical, aerospace, defense and other industries where repeatable high quality is required.

For applications requiring dissimilar inside/outside shapes, let us show you how our shaped ID tubing can eliminate broaching or other machining operations.
