Brush Engineered Materials Inc. Organized into Four Separate Reportable Segments Advanced Material Technologies and Services Advanced Material Technologies and Services consists of Williams Advanced Materials Inc. (WAM) and, beginning in the first quarter 2009, Zentrix Technologies Inc. Specialty Engineered Alloys The Specialty Engineered Alloys segment consists of Alloy Products, which includes bulk and strip form products, and beryllium hydroxide produced by Brush Resources Inc. Beryllium and Beryllium Composites The Beryllium and Beryllium Composites segment consists of Beryllium Products and Brush Ceramic Products Inc. Engineered Material Systems The Engineered Material Systems segment consists of Technical Materials, Inc.

Advanced Material Technologies and Services 2009 Sales: $460.8 million $460.8 million; 64% Manufactures precious, non-precious and specialty metal products, including vapor deposition targets, frame lid assemblies, clad and precious metal preforms, high temperature braze materials, ultra-fine wire, specialty inorganic materials, optics, performance coatings and electronic packages. Products are used in wireless, semiconductor, photonic, hybrid and other micro-electronic applications within the telecommunications and computer market. Other key markets for these products include medical, data storage, defense, security and solar energy. Williams Advanced Materials (WAM)

Specialty Engineered Alloys 2009 Sales: $172.5 million $172.5 million; 24% Manufactures and sells three main product families: strip products, bulk products and beryllium hydroxide. Strip products, the larger of the product families, include thin gauge precision strip and thin diameter rod and wire. These copper and nickel beryllium alloys provide a combination of high conductivity, high reliability and formability for use as connectors, contacts, switches, relays and shielding. Major markets for strip products include telecommunications and computer, automotive electronics, appliance and medical. Bulk products are copper and nickel-based alloys manufactured in plate, rod, bar, tube and other customized forms that, depending upon the application, may provide superior strength, corrosion or wear resistance, thermal conductivity or lubricity. Applications for bulk products include oil and gas drilling components, bearings, bushings, welding rods, plastic mold tooling and undersea telecommunications housing equipment. Beryllium hydroxide is produced by Brush Resources Inc., a wholly owned subsidiary, at its milling operations in Utah from its bertrandite mine and purchased beryl ore. The hydroxide is used primarily as a raw material input for strip and bulk products and, to a lesser extent, by the Beryllium and Beryllium Composites segment. Alloy Products

Beryllium and Beryllium Composites 2009 Sales: $47.0 million $47.0 million; 7% Manufactures beryllium-based metals and metal matrix composites in rod, sheet, foil and a variety of customized forms. These materials are used in applications that require high stiffness and/or low density and they tend to be premium-priced due to their unique combination of properties. Defense and government-related applications, including aerospace, is the largest market for Beryllium and Beryllium Composites, while other markets served include medical, telecommunications and computer, electronics (including acoustics), optical scanning and general industrial Beryllium Products

Engineered Material Systems 2009 Sales: $34.7 million $34.7 million; 5% Include clad inlay and overlay metals, precious and base metal electroplated systems, electron beam welded systems, contour profiled systems and solder-coated metal systems. These specialty strip metal products provide a variety of thermal, electrical or mechanical properties from a surface area or particular section of the material. Our cladding and plating capabilities allow for a precious metal or brazing alloy to be applied to a base metal only where it is needed, reducing the material cost to the customer as well as providing design flexibility. Major applications for these products include connectors, contacts and semiconductors while the largest markets are automotive electronics, telecommunications and computer and data storage. The energy and defense and medical electronic markets are smaller but offer further growth opportunities. Technical Materials, Inc. (TMI)
