Brief Introduction to Tungsten Alloy Part

Tungsten heavy alloy having high melting points as well as high specific gravity, tungsten is characterized by good processability. Precise control under the action of external force requires the stability of the object.

A part that is installed for this function for the stability of objects is Balance Weights. Since Balance Weights have the advantage of low volumes in case their specific gravity is higher, alloys containing at least 92% tungsten with high strength and corrosion resistance are required.

Tungsten Counterweight Parts

Counter weights made from our tungsten heavy alloy compensate for oscillations, weight transfers, imbalances and vibrations, create or shift centers of gravity and more generally ensure the optimum balance.Counterbalance weights are crucial components in many different applications. They help reduce the loads that parts are exposed to and consequently increase their service life. Such as:
Aviation and aerospace: Propeller and rotor blades, Aircraft weights
Automotive industry: Crankshaft counterweights/balancing and chassis weights, Vibration dampening governors, Balances of flywheels and turbines
Watch industry: Bobs/weights on watch rotors
Optical industry: Microscopes and measuring instruments

Key Features of Tungsten Alloy Weight

Robust construction and excellent strength
Precise dimensions therefore easy to install
Negligible maintenance and sturdiness
Excellent quality polishes to assure its rust proof nature
It is ideal for high density applications and also used in radiation shielding
The offered tungsten alloy has low alloying tendency between electrode and work-piece
Tungsten counterweight is widely used in cranes, traction lifts such as elevators, funfair rides and many others.
It is used in many rotating systems to reduce vibrations due to imbalances in the rotating assembly
Light-weight, compact and quick installation design
High tolerance and robust construction

Tungsten Pinewood Derby Weight

For cars with less than one-half of the original block remaining, lead or tungsten weight is generally required. For minimalist cars (very little wood), tungsten is generally needed to attain proper weight. For cars with one-half or more of the block remaining, then steel or zinc will work fine. 
Tungsten is a metal with one of the highest densities. It is 1.7 times heavier than lead. Only gold, platinum, and a few other rare and expensive metals have a similar density. Tungsten is non-toxic and environmentally friendly so it is gaining increased use in weighting applications where lead is not appropriate. For example lead has been banned in many streams, so tungsten is often substituted for lead weight on fishing flies.

Tungsten Alloy Crankshaft Weight


Tungsten alloy crankshaft weight, also known as tungsten alloy crankshaft balancing, is made from our tungsten heavy alloys. Crankshaft balancing is important to high performance engines in racecars, aircrafts and others. High density tungsten is perfect for crankshaft balancing with limited size and space.

For some engines it is necessary to provide tungsten alloy crankshaft weight for the reciprocating mass of each piston and connecting rod to improve engine balance. These are typically cast as part of the crankshaft but, occasionally, are bolt-on pieces. While counter weights add a considerable amount of weight to the crankshaft, it provides a smoother running engine and allows higher RPM levels to be reached.

Tungsten Weight

The special high specific density characteristics and slight or non-magnetic properties make tungsten ideal for a variety of low volume/high weight applications in the Aerospace industry. Tungsten products are installed in a variety of aircrafts and serve as balance weights in the wing fuselage, vertical (rudder) and horizontal (elevator) stabilizers, in helicopter rotors (bifilars), propellers and Aerospace instruments. The majority of balance weights that  supplies are flight safety products.Tungsten  products have been installed in more than a dozen different types of aircrafts, including the Boeing 747-400, 737, 767, 757, Gulfstream G-150 & G-200 and Sikorsky UH-60 (Black Hawk).

Different Applications of Tungsten Balancing Weight

Balancing weights are crucial components in many different applications. They help reduce the loads that parts are exposed to and consequently increase their service life. Here are a few examples:

Aviation and aerospace: propeller and helicopter blades
Automotive industry: crankshaft counterweights and chassis weights
Watch industry: bobs on watch rotors
Sports equipment: golf clubs
Optical industry: microscopes and measuring instrument
Oil and gas drilling: down hole logging tools
