The Brush Wellman Electrofusion Products facility combines the strength of Be foil fabrication, engineering, and assembly manufacturing, to offer complete processing to customer requirement.
Brush Wellman Electrofusion Products is the largest, most comprehensive resource for standard and custom beryllium window assemblies in the world including :

• Standard assemblies (Be thickness greater than 0.25 mm) ; processes are vacuum brazing, atmospheric brazing, electron beam welding, epoxy bonding and diffusion bonding, mechanical sealing
• Thin assemblies (Be thickness between 0.075 mm and 0.25 mm) ; processes include vacuum brazing, atmospheric brazing, epoxy bonding, electron beam welding & diffusion bonding, mechanical sealing
• Ultra-thin assemblies (Be thickness smaller than 0.075 mm) ; processes are diffusion bonding, epoxy bonding, mechanical sealing

The UHV vacuum products include synchrotron beamline windows (which can be actively-cooled), Be beam pipes, Be domes and cylinders, and UHV chambers.

Brush Wellman Electrofusion Products have an on-hand supply of standard size conflat flanges with the largest possible aperture size, allowing thus delivery of "standard diffusion bonded assemblies" within 3 weeks of order.

• Acoustics

The field of ultrasonics is developing rapidly and specialists in this area are constantly looking for materials which will improve the sensitivities and efficiencies of their systems. Beryllium offers a unique combination of acoustic properties that is not found in any other structural material; and it is particularly attractive for the higher frequencies (> 10 MHz) now coming into common use.

HEALTH & SAFETY
Handling beryllium-containing products in solid form poses no special health risk. Like many industrial materials, beryllium-containing materials can pose a health risk if recommended safe handling practices are not followed. Inhalation of airborne beryllium can cause a serious lung disorder in susceptible individuals.
The Occupational Safety and Health Administration (OSHA) has set mandatory limits on occupational respiratory exposures. Please read and follow the guidance in the Material Safety Data Sheet (MSDS) supplied with the material, before working with it.

• Be sheet and foils : sheet and foils are available in many grades, ranging from ultra-high purity to standard purity. Discs, straight cut windows with tight tolerances are available. A variety of surface finishes, corrosion-resistant coatings can be provided. Foil is available in 3 classifications of integrity : vacuum tight; optically dense ; as-rolled
  
• Window assemblies and ultra-high vacuum engineered products
