Standard Specification for Copper-Beryllium Alloy Rod and Bar

ABSTRACT
This specification establishes the requirements for rods and bars in straight lengths of copper-beryllium alloys with Copper Alloy UNS Nos. C17000, C17200, and C17300. The material for manufacture shall be cast and worked to such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure and specified temper in the finished product. Products shall be available in the following tempers: solution heat-treated TB00 (A), and cold-drawn hard TD04 (H), which shall be precipitation heat treated after machining or forming. Products that are already precipitation heat treated by the manufacturer shall be available in tempers TF00 (AT) and TH04 (HT). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, length, straightness, and edge contour), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements.

Overview

ASTM B196/B196M-18, published by ASTM International, specifies the requirements for copper-beryllium alloy rod and bar in straight lengths. This standard covers three main alloys: UNS C17000 (Alloy 165), C17200 (Alloy 25), and C17300. These copper-beryllium alloys are designated for applications that require high strength, non-magnetic properties, corrosion resistance, and excellent machinability.

ASTM B196/B196M-18 defines the manufacturing processes-including casting, hot and cold working, and annealing-that ensure a uniform wrought structure and specified mechanical properties. The standard provides guidance on tempers, dimensions, mechanical requirements, and chemical composition, making it a critical reference for manufacturers, suppliers, and purchasers of beryllium copper rod and bar products.

Key Topics

• Alloy Coverage: The standard addresses three beryllium copper alloys:
  • C17000 (1.7% beryllium)
  • C17200 (1.9% beryllium)
  • C17300 (1.9% beryllium with 0.4% lead for added machinability)
• Tempers:
  • Solution heat-treated (TB00/A)
  • Cold-drawn hard (TD04/H), typically precipitation heat treated after machining/forming
  • Precipitation heat-treated (TF00/AT and TH04/HT), supplied ready-to-use
• Dimensional and Mechanical Requirements:
  • Covers tolerances for diameter, length, straightness, and edge contour
  • Specifies mechanical properties such as tensile strength, yield strength, Rockwell hardness, and elongation
• Testing and Quality:
  • Products are subject to chemical composition analysis, tensile tests, and hardness testing
  • Sampling and retesting protocols are included for quality assurance
• Ordering and Certification:
  • Guidance on specifying alloy, form, temper, dimensions, and additional requirements such as mill test reports

Applications

Copper-beryllium rod and bar products manufactured to ASTM B196/B196M-18 are valued for their high strength, durability, and conductivity. Common applications include:

• Aerospace: Components requiring high strength-to-weight ratio and fatigue resistance
• Electrical Connectors: Contacts and springs that benefit from excellent electrical conductivity and reliability
• Automotive: Precision parts, such as valve seats, bushings, and bearings, requiring wear resistance
• Industrial Equipment: Non-sparking tools and components for hazardous environments
• Defense: Parts where non-magnetic and corrosion-resistant properties are critical
• Machining: Alloys like C17300 are preferred where enhanced machinability is required

Adoption of this standard ensures consistent quality, performance, and compatibility of copper-beryllium rod and bar products across industries.

Related Standards

ASTM B196/B196M-18 is part of a family of beryllium copper alloy standards. Organizations looking to implement this specification may also reference:

8. Temper
8.1 The standard temper designations available under this specification and as specified in PracticeClassification B601 are
solution heat-treated TB00 (A), and cold-drawn hard TD04 (H), (see Table 2) to be precipitation heat treated by the user. Also
available are products already precipitation heat treated by the manufacturer, tempers TF00 (AT) and TH04 (HT). These products
meet property requirements in Table 3 and normally require no further heat treatment by the user.
9. Precipitation Heat Treatment
9.1 The precipitation heat treatment is performed on TB00 (A) and TD04 (H) tempers by the purchaser, after machining or
forming.
9.2 Conformance to the TF00 (AT) and TH04 (HT) specification limits shown in Table 3, for products supplied in the TB00 (A)
or the TD04 (H) tempers, shall be determined by testing test specimens heat treated at a uniform temperature of 600 to 675°F
(316675 °F [316 to 357°C)357 °C] for the times shown in Table 4.
9.3 End products may be heat treated at other times and temperatures for specific applications. 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 mechanical requirements of
Table 3 do not apply to such special heat treatments. Specific test requirements as needed shall be agreed upon between the
manufacturer or supplier and purchaser of the end product.
9.4 TF00 (AT) and TH04 (HT) tempers as standard mill-hardened products have been precipitation heat treated and tested by
the manufacturer for conformance to the specification limits shown in Table 3. Further thermal treatments of these tempers are not
normally required.
