Brush Wellman Receives Aluminum Beryllium Investment Casting Patent.CLEVELAND--(BUSINESS WIRE)--July 14, 1997--Brush Wellman Inc. (NYSE-BW) today announced that it has received a patent for investment casting investment casting Precision casting for forming metal shapes with minutely precise details. Casting bronze or precious metals typically involves several steps, including forming a mold around the sculptured form; detaching the mold (in two or more sections); coating its of aluminum beryllium beryllium (bərĭl`ēəm) [from beryl ], metallic chemical element; symbol Be; at. no. 4; at. wt. 9.01218; m.p. about 1,278°C;; b.p. 2,970°C; (estimated); sp. gr. 1.85 at 20°C;; valence +2. alloys. The patent, US 5,642,773, entitled "Aluminum Alloys Containing Beryllium and the Investment Casting of Such Alloys" was issued on July 1, 1997. The use of investment cast aluminum beryllium components is growing in aerospace, robotics robotics, science and technology of general purpose, programmable machine systems. Contrary to the popular fiction image of robots as ambulatory machines of human appearance capable of performing almost any task, most robotic systems are anchored to fixed positions , defense, and a variety of other high-performance applications. The issue of this patent closely follows others related to aluminum beryllium alloys, applications and processing. Patent No. 5,551,997, entitled "Beryllium-containing Alloys of Aluminum and Semi-solid Processing of Such Alloys" and No. 5,578,146 entitled "Aluminum Beryllium Alloys Having High Stiffness and Low Thermal Expansion thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. for Memory Devices" were issued in September 1996 and November 1996, respectively.
