Product details

ASTM B777 is a standard specification for tungsten and tungsten alloy bars, rods, and wire. This standard covers the requirements for both unalloyed tungsten and tungsten alloys, including their chemical composition, mechanical properties, and dimensional tolerances.

Key Points of Tungsten alloy bar:

1. Chemical Composition:

The standard specifies the permissible levels of impurities and the required purity of tungsten.

For unalloyed tungsten, the primary element is tungsten, with very low levels of other elements such as oxygen, nitrogen, and carbon.

For tungsten alloys, the standard may include specific percentages of other elements like nickel, iron, and copper, depending on the grade.

2. Mechanical Properties:

The standard includes requirements for tensile strength, yield strength, elongation, and hardness.

These properties are critical for ensuring that the tungsten bar or rod can withstand the intended application.

3. Dimensional Tolerances:

The standard specifies allowable tolerances for the dimensions of the bars, rods, and wire, including diameter, length, and straightness.

These tolerances ensure that the product meets the required specifications for its intended use.

4. Testing and Inspection:

The standard outlines the methods for testing the material, including chemical analysis, mechanical testing, and non-destructive testing (NDT).

It also specifies the acceptance criteria for these tests.

5. Applications:

Tungsten and tungsten alloy bars, rods, and wire made to ASTM B777 are used in a variety of applications, including:

Electrical contacts

High-temperature applications

Medical devices

Aerospace components

Welding electrodes

Grades and Alloys:

Unalloyed Tungsten: Pure tungsten with minimal impurities.

Tungsten Alloys: Typically include small amounts of other elements to enhance specific properties, such as increased ductility or improved machinability.

Compliance and Certification:

Manufacturers must comply with the requirements of ASTM B777 to ensure that their products meet the specified standards.

Products that meet the standard are often certified and may come with a material test report (MTR) or certificate of conformance.
