overview
Tungsten alloy counterweight is fabricated using powder metallurgy and precision CNC machining. This high-density, high-precision gravity balance component features compact size, superior hardness, excellent corrosion resistance, and eco-friendly performance.Widely applicable to industrial equipment, precision instruments, auto parts, aerospace parts, marine facilities, and fishing tackle, it excels in gravity adjustment, dynamic balance correction, vibration dampening, and speed stabilization. FANMETAL provides standard products from stock and also supports custom non-standard shapes and large-scale production.
Features of Tungsten Alloy Counterweight
Extremely high density
Density reaches 16.5–18.75 g/cm³, which is three times that of ordinary carbon steel counterweights and 1.6 times that of lead counterweights. It can be used for installation scenarios of compact precision equipment and small instruments, saving internal structural space and far surpassing ordinary counterweight materials.
Excellent corrosion and oxidation resistance
Tungsten balance weight has stable chemical properties and excellent rust resistance, oxidation resistance, and corrosion resistance. Its service life is several times that of ordinary cast iron or lead counterweights, effectively reducing the cost of replacing equipment parts and maintaining equipment.
Green and environmentally friendly
Non-toxic and harmless, compliant with global RoHS and REACH environmental regulations, making it the ultimate compliant alternative to toxic lead weights.
Outstanding mechanical strength
High tensile strength and high hardness, ensuring dimensional and structural stability even under extremely harsh and high-load dynamic working conditions and environments.
Applications of tungsten balance weight
Our tungsten alloy weight delivers excellent comprehensive performance and versatile adaptability, catering to precision weighting, dynamic balancing, vibration reduction, and speed stabilization needs in multiple sectors.

Industrial Machinery
Ideal dynamic balance components for rotating equipment, including precision machine tools, fans, and electric motors. It suppresses vibration and noise efficiently, and maintains reliable performance during high-speed operation.

Outdoor Fishing Tackle
Core parts for high-end fishing gear. Functioning as tungsten heavy alloy fishing jigs and fishing reel counterweights, they are compact, sink rapidly, and ensure precise casting. They are a superior replacement for conventional toxic lead sinkers.

Marine Industry
Supplying balancing weights for yachts, fishing vessels, and surface operation platforms, helping hulls remain stable in complex wind and wave environments to substantially improve navigation safety.

Aerospace Industry
Used as precision counterweights for aircraft, artificial satellites, and various aerospace parts for posture adjustment and gravity calibration. All products satisfy stringent demands for high precision and long-term reliability.Learn more about our products: Tungsten Aviation Balance Weights

Automotive
Tungsten alloy ballast is widely installed on crankshafts, chassis, and car bodies for vibration damping and weighting purposes. It optimizes the vehicle's center of gravity, reduces shaking and bumping while driving, and upgrades overall controllability and smoothness.

Medical & Optical Instruments
Used as center-of-gravity adjustment components for CT scanners, MRI machines, and other medical equipment, as well as sophisticated optical instruments. It prevents gravity offset and ensures stable operation and detection accuracy of high-sensitivity devices.
Production Process of Tungsten Alloy Weight
Raw Material Batching
High-purity tungsten powder is mixed with nickel-iron or nickel-copper powder in precise proportions according to application requirements, to form a qualified composite powder.
Compaction Forming
The mixed powder is pressed into compact blanks by hydraulic or isostatic pressing. The blanks feature dense structure and uniform density without internal pores.
Vacuum Sintering
Blanks are sintered under a high temperature and vacuum environment. This process greatly improves the overall strength, compactness, and corrosion resistance of tungsten alloy.
Precision CNC Machining
Sintered workpieces are processed by the lathe, milling machine, and grinder. We can produce various shapes and sizes with tight tolerance to meet customized demands.
Surface Treatment
Polishing, sandblasting, or passivation are available for surface finishing, to enhance anti-rust and anti-oxidation ability.
Final Inspection
All finished products go through full inspection on density, size, appearance, and mechanical properties before delivery.

Packaging & Shipping
Designed for the high-density, high-precision, and abrasion-prone nature of our tungsten alloy counterbalance, we use a custom protective packaging solution that meets the strict demands of international sea and air freight.
Each batch of parts is first sealed in plastic bags (vacuum-packaged for moisture resistance), then fully secured with shock-absorbing foam to prevent scratches, impacts, and wear during transit. The entire unit is then packed into a heavy-duty reinforced carton or wooden crate to withstand the heavy weight of the products, ensuring safe delivery worldwide.

FAQ
Q: What is the difference between W-Ni-Fe and W-Ni-Cu tungsten alloy counterweights?
A: Both alloys offer high density and precision, but they serve different needs. W-Ni-Fe provides superior tensile strength and hardness, making it ideal for heavy-duty industrial and automotive applications. W-Ni-Cu, on the other hand, is strictly non-magnetic, making it the preferred choice for aerospace, precision instruments, and electronic equipment where magnetic interference must be avoided.
Q: Why choose tungsten alloy over traditional materials like lead or steel for counterweights?
A: Tungsten alloy has a density nearly twice that of steel and 1.6 times that of lead. This allows us to design counterweights with a much smaller volume and compact size, saving crucial space in aerospace and automotive assemblies. Additionally, tungsten is non-toxic, eco-friendly, highly corrosion-resistant, and offers better vibration damping than steel.
Q: Are you a manufacturer or a trading company?
A: We are a manufacturer with professional technology and several years of production experience, and can provide customers with various high-quality products.
Q:Do you accept custom orders?
A:Yes, we accept. We will design and produce products according to the specific information you provide, and also assure you that we will try our best to come up with the best solution to provide you with high-quality products.
