High-Specific-Gravity Tungsten Alloy Counterweight
1. What's High-Specific-Gravity Tungsten Alloy Counterweight?
High-specific-gravity tungsten alloy counterweight is high-density tungsten-based alloy counterweight component with tungsten as the matrix, typically containing 90%–97% tungsten, prepared by adding binder phases such as nickel, iron or copper through powder metallurgy liquid-phase sintering. CTIA's high-specific-gravity tungsten alloy counterweight generally has a density of 16.7–18.8 g/cm³, significantly higher than traditional lead (about 11.3 g/cm³) and steel (about 7.8 g/cm³). It concentrates mass in an extremely small volume to achieve center-of-gravity adjustment, dynamic balance and vibration suppression, and is widely used in transportation, aerospace, precision instruments and high-end equipment.
2. Why Choose High-Specific-Gravity Tungsten Alloy for Counterweight?
High-specific-gravity tungsten alloy is chosen as a counterweight material because it combines high density, small volume, high strength and good machinability, meeting equipment requirements for mass configuration, balance control and long-term stable operation.
(1) High Density, Small Volume: High density means that under the same mass the volume is significantly smaller than that of steel and lead, making it suitable for space-constrained structural designs.
(2) Precise Balance, Vibration Control: The high-density characteristic concentrates mass within limited space. By adjusting counterweight position and mass distribution, center-of-gravity regulation, dynamic balance and vibration suppression can be achieved, suitable for rotating components and precision equipment.
(3) Excellent Mechanical Properties: Tensile strength of 700–1200 MPa and hardness of about 25–35 HRC, combined with good toughness and fatigue resistance, enable it to withstand high-speed rotation and alternating loads.
(4) Good Environmental Adaptability: Non-toxic and non-radioactive, with corrosion resistance and high-temperature stability, meeting long-term use requirements in medical, aerospace, precision instruments and industrial equipment fields.
