Tungsten Rod Castlebar Grade 9008 C2 Sub‑Micron Rod

Description

Product Overview

The Castlebar tungsten rod is engineered to meet the most rigorous standards of modern industry. Crafted from Grade 9008/C2 material, it contains 10% cobalt which enhances ductility while preserving the extreme hardness characteristic of tungsten alloys. The rod features a sub‑micron grain size, delivering a uniform microstructure that translates into consistent mechanical performance across the entire length. With a hardness rating of HRa 92 and a tensile strength of at least 3500 MPa, the rod can withstand high‑stress environments without deformation. Dimensional precision is guaranteed by an h6 tolerance of +0/‑0.00035 inches, and the surface is polished to a maximum roughness of 3.9 μin Ra, minimizing friction and wear during contact operations. Weighing only 2.4 ounces and measuring 2 × 0.37 × 0.37 inches, the rod offers a compact form factor that is easy to handle while delivering the power of a full‑size tungsten component.

Usage

Designed for a broad spectrum of industrial applications, this tungsten rod excels in scenarios where strength, wear resistance, and dimensional accuracy are paramount. In precision machining, the rod serves as a cutting insert or a guide component, maintaining edge stability even under high feed rates and temperatures. Tooling manufacturers rely on its hardness to produce drills, taps, and reamers that retain geometry over extended service lives. Aerospace and defense sectors benefit from the rod’s ability to endure extreme loads, making it suitable for missile components, turbine blades, and high‑performance fasteners. In medical device fabrication, the biocompatible nature of tungsten combined with its radiopacity provides a reliable material for surgical instruments and imaging markers. Additionally, the polished finish reduces the need for secondary lubrication, simplifying integration into automated production lines. The rod’s compact dimensions also make it ideal for prototype development where space constraints demand high performance in a small package.

FAQ

What does the grade 9008/C2 designation mean?

Grade 9008/C2 indicates a tungsten alloy containing approximately 10% cobalt. The cobalt improves ductility while maintaining the high hardness and density of pure tungsten, making the material suitable for demanding industrial uses.

Can this rod be machined with standard CNC equipment?

Yes, the rod can be machined using conventional CNC machines. However, due to its high hardness, it is recommended to use carbide tooling and appropriate cutting speeds to achieve optimal results and avoid excessive tool wear.

What is the recommended storage condition for the rod?

Store the rod in a dry, temperature‑controlled environment, preferably in a sealed container to prevent oxidation. While tungsten is naturally resistant to corrosion, maintaining a stable environment helps preserve its surface finish and dimensional stability.

Is the rod compatible with high‑temperature applications?

The tungsten alloy retains its mechanical properties at elevated temperatures, making it suitable for applications such as furnace components, aerospace parts, and high‑heat tooling where other materials might soften or degrade.
