II. Definition of Tungsten Carbide with Non-Magnetic Properties

Tungsten carbide with non-magnetic properties, abbreviated as non-magnetic tungsten carbide, is a type of tungsten carbide that does not magnetize in a magnetic field. Its magnetic permeability is much lower than that of air, exhibiting non-magnetic or weakly magnetic properties. This new type of hard alloy is produced through powder metallurgy techniques and sintered in a high-temperature vacuum environment, primarily composed of refractory metal carbides and iron-group transition metals. The carbide hard phase imparts its high hardness and wear resistance.

III. Characteristics of Tungsten Carbide with Non-Magnetic Properties

• Non-magnetic or Weakly Magnetic: Remains stable in magnetic environments without magnetization.
• High Hardness and Wear Resistance: Maintains excellent performance even under harsh conditions.
• Excellent Bending Strength: Unique manufacturing process enables it to withstand significant external forces.
• Good Corrosion Resistance: Strong resistance to acidic and alkaline corrosive media.

IV. Manufacturing Process of Tungsten Carbide with Non-Magnetic Properties

The manufacturing of tungsten carbide with non-magnetic properties employs powder metallurgy techniques. Raw materials such as carbides and binders are mixed and ball-milled to produce a uniform alloy powder. Through precisely controlled sintering processes, dense alloy materials are formed. By adjusting sintering parameters, tungsten carbide with different grain sizes and properties can be obtained.
