7. Current Status: Withdrawn Standard

ASTM International officially withdrew ASTM A279. The exact year of withdrawal varies in records, but the standard is no longer recognized for new construction in most jurisdictions.

  1. Scope: The standard covers hard-drawn tantalum wire in various diameters, intended for use in electronic components.
  2. Referenced Documents: The document lists other ASTM standards and publications referenced in the specification.
  3. Terminology: Definitions of terms specific to the standard, such as "hard-drawn" and "tantalum wire," are provided.
  4. Ordering Information: The standard outlines the information that should be provided when ordering tantalum wire, including diameter, length, and surface finish.
  5. Materials and Manufacture: Requirements for the tantalum wire, including chemical composition, microstructure, and processing, are specified.
  6. Requirements: The standard details the necessary properties and testing methods for the wire, such as:

    | Element | Composition, % | | --- | --- | | Carbon | 0.18-0.28 | | Manganese | 1.00-1.50 | | Silicon | 0.15-0.35 | | Copper | 0.20-0.50 | | Vanadium | 0.01-0.10 | Scope : The standard covers hard-drawn tantalum wire

    While the original standard is no longer active, the term "ASTM A279" is frequently used by manufacturers and suppliers to refer to high-precision stainless steel products—particularly bars, shapes, and tubes—often in conjunction with active standards like ASTM A276 (for bars and shapes) or ASTM A269 (for tubing).
