Quarter inch Tungsten Carbide Rod Castlebar Polished Grade 9008 C2

Description

Product Overview

The 1/4″ × 2-1/2″ cemented tungsten carbide round rod from Castlebar is engineered for demanding industrial environments where material performance cannot be compromised. Constructed from a high‑grade 9008/C2 alloy containing 10% cobalt, the rod offers a sub‑micron grain size that translates into a uniform microstructure and exceptional wear resistance. The surface is ground, polished, and chamfered to a maximum roughness of 3.9 μin Ra, delivering a mirror‑like finish that reduces friction and eases integration into precision assemblies. With a hardness rating of HRa 92 and a tensile strength of at least 3500 MPa, this rod meets the rigorous standards required for aerospace, medical, and high‑precision tooling applications. Its compact dimensions—2.5 in length, 0.25 in diameter, and a weight of 1.52 oz—make it easy to handle, store, and install while providing the mechanical robustness needed for long‑term service.

Usage

Designed for versatility, this tungsten carbide rod excels in a variety of high‑performance scenarios. In aerospace manufacturing, it serves as a core component for turbine blade inserts, where its high temperature stability and resistance to oxidation are critical. In the medical field, the rod is used for surgical instrument tips and implantable devices, benefiting from its biocompatibility and ability to retain sharp edges after repeated sterilization cycles. Precision tooling applications, such as CNC machining, micro‑drilling, and die‑cutting, leverage the rod’s superior hardness and polished surface to achieve tighter tolerances and longer tool life. Additionally, the rod’s compact size makes it suitable for custom fixtures, prototype development, and research laboratories where material consistency and repeatability are paramount.

FAQ

What does the Grade 9008/C2 designation mean?

Grade 9008/C2 indicates a tungsten carbide alloy with 10% cobalt binder, offering a balance of high hardness (HRa 92) and excellent toughness, suitable for high‑stress and wear‑resistant applications.

Can this rod be used for high‑temperature environments?

Yes, tungsten carbide maintains its mechanical properties at elevated temperatures, making the rod appropriate for aerospace and industrial processes that involve heat exposure.

Is the polished finish necessary for all applications?

The polished finish minimizes surface friction and helps achieve tighter tolerances, which is beneficial for precision tooling, but the rod can also be used in applications where a rougher finish is acceptable.

How do I determine the correct size for my project?

Refer to the product dimensions (2.5 in length, 0.25 in diameter) and compare them with your design specifications. If a different size is required, Castlebar offers custom machining services.

What warranty or support does Castlebar provide?

Castlebar offers a limited warranty covering material defects and provides technical assistance throughout the product lifecycle, including machining recommendations and post‑sale support.
