5/16″ X 3-1/2″ Grade 9008/C2 Tungsten Carbide Rod Polished Castlebar

Description

Product Overview

The 5/16″ X 3-1/2″ Grade 9008/C2 cemented tungsten carbide round rod from Castlebar is engineered for the most demanding industrial environments. Crafted from a high‑grade tungsten carbide matrix with 10% cobalt binder, the rod exhibits a sub‑micron grain structure that delivers superior hardness (HRa 92.0) and a tensile‑strength rating of at least 3500 MPa. The surface is ground, polished, and chamfered to a maximum roughness of 3.9 μin Ra, providing a smooth finish that reduces friction and wear in high‑speed applications. Dimensional precision is guaranteed by an h6 tolerance of +0/‑0.00035 inches, ensuring consistent performance across batches.

Usage

This rod is ideally suited for a range of high‑performance applications, including precision machining, cutting tools, wear‑resistant components, and aerospace hardware. Its exceptional hardness and wear resistance make it a reliable choice for drilling, milling, and turning operations where tool life and dimensional stability are critical. The polished chamfered edges reduce chip adhesion and improve material flow, enhancing efficiency in metal‑forming processes. Additionally, the rod’s high tensile strength supports load‑bearing applications such as inserts for composite materials, high‑temperature furnace components, and medical device manufacturing where biocompatibility and durability are required.

FAQ

What does Grade 9008/C2 mean?

Grade 9008/C2 indicates a tungsten carbide material with a hardness of HRa 92.0 and a cobalt binder content of 10%. This grade provides a balance of high hardness, toughness, and wear resistance suitable for demanding machining applications.

Can this rod be used for high‑temperature applications?

Yes. The cemented tungsten carbide composition retains its mechanical properties at elevated temperatures, making it appropriate for furnace components, high‑speed cutting tools, and other high‑heat environments.

What is the benefit of the polished chamfered finish?

The polished chamfered finish reduces edge chipping, improves material flow, and lowers friction during cutting or forming operations, which enhances tool life and product quality.

How do I verify the dimensional tolerance?

Each rod is measured with calibrated micrometers and coordinate‑measuring machines (CMM) to confirm the h6 tolerance of +0/‑0.00035 inches before shipment.

Is custom sizing available?
