Beryllium

Among structural metals, beryllium has a unique combination of properties. It has low density (two-thirds that of aluminum), high modulus per weight (five times that of ultrahigh-strength steels), high specific heat, high strength per density, excellent dimensional stability, and transparency to X-rays. Beryllium is expensive, however, and its impact strength is low compared to values for most other metals. Available forms include block, rod, sheet, plate, foil, extrusions, and wire. Machining blanks, which are machined from large vacuum hot pressings, make up the majority of

Light Alloys and Metals
Light alloys and light metals have low density and high strength-to-weight ratios. Light weight metals include aluminum, magnesium, titanium, and beryllium alloys.
Refractory and Reactive Metals
Refractory metals are a class of metals that are extraordinarily resistant to heat and wear and have extremely high melting points. Reactive metals have a strong affinity for oxygen and nitrogen at elevated temperatures and are highly resistant to corrosion at low temperatures.
Metal Extrusions
Metal extrusions are metals or alloys that are extruded into bars, rods, angles, channels, tees, or other profile shapes. Examples of the metals and alloys that can be extruded are lead, tin, aluminum, copper, titanium, zinc, and steel.
Specialty Nonferrous Metals and Alloys
Specialty nonferrous metals and alloys include metals such as hafnium, zirconium, beryllium, tantalum or osmium with unique properties for specific applications.
Oxide Ceramics
Oxide ceramics include alumina, zirconia, silica, aluminum silicate, magnesia and other metal oxide based materials.
