Is Tungsten Carbide Magnetic? KOIHO BETTER CARBIDE`s Expert Insights

Understanding Tungsten Carbide’s Magnetic Properties

Tungsten carbide (WC) is a composite material produced through powder metallurgy, which combines tungsten carbide particles with a metallic binder, typically cobalt (Co). Pure WC is non-magnetic, but the cobalt binder (5-15% by weight in most grades) imparts weak ferromagnetism. The degree of magnetism depends on the cobalt content and manufacturing process. KOIHO BETTER CARBIDE’s cemented carbide products, such as tungsten carbide rods and hard alloy milling teeth, are engineered with precise binder ratios to minimize magnetism for applications like MRI-compatible tools or high-precision machining.

Is Tungsten Carbide Magnetic? Key Factors

1. Cobalt Binder Content

Cobalt is ferromagnetic, and higher cobalt percentages (e.g., 10-15% in YG10-grade carbide tungsten rods) increase magnetism. Low-cobalt grades (e.g., 6% in YG6 cemented carbide milling teeth) or nickel-bound alternatives reduce magnetic properties. KOIHO offers hard alloy 3D printing nozzles with nickel binders for near-non-magnetic performance in sensitive 3D printing tasks.

2. Manufacturing Process

The powder metallurgy process affects magnetic properties. Residual stresses or impurities can enhance magnetism. KOIHO’s advanced sintering techniques ensure tungsten carbide bars with consistent, low-magnetic profiles, ideal for precision tools on CNC machines.

3. Application Requirements

In industries like aerospace or medical device manufacturing, non-magnetic tools are critical to avoid interference with magnetic fields. KOIHO’s carbide milling teeth and hard alloy 3D printing nozzles are designed for low or no magnetism, supporting applications from road milling on Wirtgen machines to printing with Creality Ender-3.

Why Magnetism Matters in Tungsten Carbide Applications

• Precision Machining: Magnetic carbide tungsten rods can attract metal particles, affecting tool accuracy. KOIHO`s low-magnetic tungsten carbide bars ensure clean cuts in CNC machining of titanium alloys.
• Road Milling: Cemented carbide milling teeth with minimal magnetism prevent debris buildup, enhancing efficiency on Sandvik planers during asphalt milling.
• 3D Printing: Magnetic hard alloy 3D printing nozzles may interfere with printer electronics. KOIHO’s nickel-bound carbide nozzles deliver non-magnetic precision for abrasive filaments like carbon fiber PLA.
• Medical and Aerospace: Non-magnetic tungsten carbide products are essential for MRI environments or satellite components. KOIHO’s tailored solutions meet stringent standards.
