Site by Infinity Arts. Your comments are invited either for revision of this standard or for additional standards and should be addressed to Awtm International Headquarters.
This specification establishes atm requirements for rods and bars in straight lengths of copper-beryllium alloys with Copper Alloy UNS Nos. The capacity for cold working this alloy asfm rated as “excellent”. The following three alloys are included: Mechanical Property Requirements TF00 Solution heat treated AT up to 3, incl.
Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 5 distributors but is also available to a lesser extent in Wire Products, and Flat Rolled Products. C, C, or C, wstm and worked and of such purity and soundness as to be suitable for processing into the products prescribed herein.
The machinability rating of this alloy is Link to Active This link will always route to the current Active version of the n196.
ASTM B / BM – 18 Standard Specification for Copper-Beryllium Alloy Rod and Bar
This standard has been approved for use by agencies of the Department of Defense. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Originally approved in to replace portions of B — 41 T.
A number in parentheses indicates the year of last reapproval. Astn tension test should not be made except when indicated by the purchaser. C can develop more than atm MPa tensile strength. Within the text, the SI units are shown in brackets.
ASTM B / BM – 07 Standard Specification for Copper-Beryllium Alloy Rod and Bar
This was corrected to the proper 10 — 25 incl. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Approved April 1, 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 from our strategically located facilities around the world.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Work Item s – proposed revisions of this standard. The mechanical requirements of Table 3 do not apply to such special heat treatments.
The hot forgeability rating of this alloy is “not recommended”. C, C, and C The following three alloys are included: One is to be tested in the as-sampled condition, and one in the precipitation heat-treated condition.
This abstract is a brief summary of the referenced standard.
NOTE 1—Mechanical property data determined on other than round cross sections, for sizes under 0. The annealing temperature for this alloy is between F. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Additional sizes available, not all sizes shown are available from stock. Historical Version s – view previous versions of standard. Number of Tests and Retests Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional diameter, length, straightness, and edge contourmechanical tensile and yield strength, Rockwell hardness, and elongationand chemical composition requirements.
The tensile strength requirements shall be prescribed in Table 2 and Ast 3 after precipitation heat treatment in accordance with 8.
Beryllium Copper Bar
Now offering hollows upon request. Full cross section or machined specimens shall be as speci? Soldering is rated as “good”, brazing is rated as “good”, oxyacetylene welding is “not recommended”, gas shielded arc welding is rated as “good”, coated metal arc welding is rated as “good”, spot welding is rated as ” good”, seam welding is rated as ” fair”, and butt welding is rated as “fair”.
These products meet property requirements in Table 3 and normally require no further heat treatment by the user. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The following three alloys are included:. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
