This was corrected to the proper 10 — 25 incl. Number of Tests and Retests It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This alloy’s capacity for being hot formed is rated as “good”. Link to Active This link will always route to the current Active version of the standard.

Further thermal treatments of these tempers are not normally required. The mechanical requirements of Table 3 do not apply to such special heat treatments. The hardness requirements shall be as prescribed in Table 2 for solution heat treated or solution heat treated and cold worked and in Table 4 after prescribed heat treatment. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Workmanship, Finish and Appearance The tension test should not be made except when indicated by the purchaser. Full cross section or machined specimens shall be as speci?

Additional sizes available, not all sizes shown are available from stock. We specialize in beryllium bar, but offer an additional selection of beryllium copper bar in a variety of additional specifications and offer cut to length programs n196 our strategically located facilities around the world.


Beryllium Copper Bar, Beryllium Copper Round Bar – Beryllium Round Copper Bar

Originally approved in to replace portions of B — 41 T. Beryllium Coppers are available in ductile, heat treatable tempers and in mill hardened tempers. These special combinations of properties such as increased ductility, electrical conductivity, dimensional accuracy, endurance life, and resistance to elastic drift and hysteresis in springs, may be obtained by special precipitation-hardening heat treatments.

The tensile strength requirements shall be prescribed in Table 2 and Table 3 after precipitation heat treatment in accordance with 8.
