This specification covers beryllium in the form of sheet and
plate produced by hot rolling beryllium.
Thickness 0.020 to 0.250 inch (0.51 to 6.35 mm),
Thickness over 0.250 inch (6.35 mm).
These products have been used typically for parts requiring high
strength-to-weight ratio and high modulus of elasticity, but usage
is not limited to such applications.
There are three sheet and plate classifications based on
flatness tolerances (See 3.5.5). 1.4 Safety - Hazardous Materials
While the materials, methods, applications, and processes described
or referenced in this specification may involve the use of
hazardous materials, this specification does not address the
hazards that may be involved in such use. It is the sole
responsibility of the user to ensure familiarity with the safe and
proper use of any hazardous materials and to take necessary
precautionary measures to ensure the health and safety of all
Inhaling dust or fumes containing beryllium may cause chronic
beryllium disease, a serious chronic lung disease, in some
individuals. Over time, lung disease can be fatal. Read the product
specific Safety Data Sheet (SDS) for additional environmental,
health and safety information before working with beryllium or
