CTIA GROUP's non-magnetic tungsten alloy rings are toroidal tungsten alloy components manufactured using a specific alloy formula that exhibit almost no magnetization in a magnetic field. The core characteristic of non-magnetic alloys lies in the addition of non-magnetic elements. Common types of non-magnetic tungsten alloy rings include tungsten-nickel-copper alloy (WNiCu), tungsten-nickel-molybdenum alloy (WNiMo), tungsten-copper alloy (WCu), tungsten-silver alloy (WAg), tungsten-rhenium alloy (WRe), and tungsten-tantalum alloy (WTa).
1. Main Characteristics of Non-Magnetic Tungsten Alloy Rings
High Density: Their density typically ranges from 16.5 g/cm3 to 18.8 g/cm3, more than twice that of ordinary steel. This means they can provide a large mass within a very small volume.
Non-Magnetic: By controlling the magnetic properties of the added alloying elements, tungsten alloy rings can achieve extremely low magnetic susceptibility, down to the order of 10??, meeting the requirement of zero interference in strong magnetic field environments.
High Strength: Its tensile strength is typically between 700MPa and 1200MPa, while also possessing a certain elongation (e.g., 5%-15%), enabling it to withstand significant impact and vibration.
High Temperature Resistance: Tungsten's melting point is as high as 3422℃, allowing the non-magnetic tungsten alloy ring to maintain structural stability even at high temperatures.
Corrosion Resistance: The non-magnetic tungsten alloy ring exhibits excellent resistance to acid and alkali corrosion and oxidation, making it suitable for various harsh environments.
Radiation Shielding Capability: Due to its high density, it has a strong absorption capacity for X-rays and gamma rays, making it an ideal alternative to lead materials in the medical and nuclear industries.
Good Biocompatibility: Non-magnetic tungsten alloy systems, represented by tungsten-nickel-copper (WNiCu), demonstrate excellent corrosion resistance in environments such as physiological saline, making them suitable for medical equipment.
2. Key Applications of Non-magnetic Tungsten Alloy Rings
Based on its core advantages of high specific gravity and non-magnetic properties, CTIA GROUP's non-magnetic tungsten alloy rings are widely used in high-precision fields requiring protection from magnetic field interference. Including:
Medical field: Used in the manufacture of core components such as gradient coil shields and collimation rings for magnetic resonance imaging (MRI), ensuring that they do not interfere with the strong magnetic field of MRI equipment and guaranteeing image quality.
Aerospace: Used as gyroscope rotors or high-precision counterweight rings in inertial navigation systems. Their high density generates greater inertial torque to improve attitude control accuracy, while their non-magnetic nature avoids interference with sensitive equipment such as spaceborne magnetometers.
Defense and military industry: Used in components such as ammunition and pre-fragmentation rings. High density ensures efficient kinetic energy in tungsten alloy ammunition, while the material itself is non-toxic and harmless.
Precision instruments: Used as key supports or counterweight rings in precision equipment such as missile guidance systems and oil drilling directional measurement instruments; in the consumer electronics field, as counterweights in linear vibration motors for smartphones, providing accurate vibration feedback in a very small space while avoiding magnetic field interference with screen touch or wireless charging.
High-voltage electrical appliances: Utilizing their high conductivity, arc resistance, and high strength, they can be used as electrical contacts or protective rings in switches.
