High Quality Carbide Bar Various Size Carbide Rods

Overview

High Quality Carbide Bar & Various Size Carbide Rods are versatile tungsten carbide products designed to meet the diverse needs of precision manufacturing, offering a comprehensive range of diameters, lengths, and grades. These bars and rods are fabricated from premium WC-Co composites, combining exceptional hardness with tailored mechanical properties to excel in both cutting and forming applications. Whether used as raw material for tool production or as finished components, they deliver consistent performance across industries that demand uncompromising quality.

Available in standard sizes from 1mm to 200mm in diameter and up to 3,000mm in length, these products cater to everything from micro-drilling tools to large-scale stamping dies. Advanced manufacturing processes—including cold isostatic pressing (CIP) and vacuum sintering—ensure uniform density, minimal defects, and precise dimensional control, making them the preferred choice for applications where tool life and accuracy are critical.

Features

Dimensional Versatility: Wide range of diameters (0.5mm–200mm) and lengths (50mm–3,000mm), with custom sizes available to meet unique project requirements.

Grade Customization: Multiple cobalt contents (3%–20%) and grain sizes (0.5μm–5μm) to balance hardness, toughness, and wear resistance for specific materials (e.g., ferrous vs. non-ferrous machining).

Surface Finish Excellence: Ground or polished surfaces (Ra ≤ 0.2μm) reduce friction in tool holders and minimize stress concentrations, enhancing overall tool performance.

High Impact Resistance: Cobalt-rich grades (15%–20% Co) absorb shock in interrupted cutting operations, such as milling cast iron or stainless steel with scale.

Compliance with International Standards: Meet or exceed ISO 3364, ASTM B316, and DIN 7991 for chemical composition, physical properties, and dimensional accuracy.

Applications

Tool Manufacturing: Raw material for end mills, reamers, and broaches used in automotive engine machining, where tight tolerance on connecting rod bores is essential.

Aerospace Tooling: Precision rods for electrical discharge machining (EDM) electrodes, shaping complex titanium alloy structures with micron-level accuracy.

Industrial Forming: Carbide bars as punches and dies in sheet metal stamping, enduring high compressive forces when forming high-strength steel components.

Medical Device Production: Micro rods for manufacturing orthopedic drill bits, ensuring clean cuts in bone tissue with minimal heat generation.

FAQ

Q: How do I select the right cobalt content for my application?

A: Low cobalt (3–6%) is ideal for non-ferrous machining (aluminum, copper) requiring extreme hardness. Medium cobalt (8–12%) balances hardness and toughness for general steel machining. High cobalt (15–20%) is best for cast iron or interrupted cuts where impact resistance is critical.

Q: Can these bars be machined into custom geometries?

A: Yes, they can be ground, EDM’d, or laser-cut into complex shapes. We recommend using diamond-based abrasives to maintain precision and avoid cobalt binder loss.

Q: What packaging options are available to prevent damage during shipping?

A: Bars are individually wrapped in anti-oxidation paper and packed in foam-lined wooden crates to prevent mechanical damage and moisture exposure.

Q: Do you offer material certification for traceability?

A: Yes, each batch includes a mill certificate with chemical composition, hardness, density, and mechanical test results, compliant with aerospace and medical industry traceability requirements.
