Abstract
Important changes in manufacturing beryllium powder products, mentioned in Chapter 2, have improved the mechanical properties of most mill products; data on earlier products (prior to 1970) are often obsolete. Block formerly showed about 1% elongation; it is now 3.0% minimum, usually about 4%. Sheet averages 15–20% elongation with a guaranteed 10% (formerly 5%). The strain-hardening coefficient has been improved significantly.
