Tungsten alloy collimator is a component of the radiation head of medical accelerator. In addition to the primary and secondary collimators, an electron beam limiter is installed under the radiation head to limit the range of electron radiation in order to protect normal tissues outside the target area and prevent critical organs from being irradiated.

According to the way of fragment generation, tungsten alloy prefabrication fragment can be divided into three types: natural fragments, pre-controlled fragments and prefabricated fragments. It forms a three-dimensional killing area in space. The shape and size of the three-dimensional killing area is determined by the scattering characteristics of the fragments. The main parameters of fragment scattering characteristics include fragment scattering angle and direction angle, and the distribution variance of the distribution density of fragment numbers along the direction angle.

Whether the fragment can effectively kill the target is closely related to the speed, shape and quality of the fragment hitting the target, and tungsten alloy material can meet this requirement. Chinatungsten Online has been engaged in the production and sales of tungsten alloy fragment rings for more than 20 years, and can provide high-quality products according to customer requirements.

The tungsten alloy counterweight crankshaft is used to balance the rotational inertia force and moment generated by the connecting rod big end, connecting rod journal and crank, so that the engine crankshaft runs smoothly. Some counterweight crankshafts are made integrally with the crankshaft, which is an extension of the crankshaft, and some are separately made parts, which are fixed on the crank with bolts.

Tungsten alloy has the advantages of small size, high density, high hardness, high wear resistance, strong corrosion resistance, strong impact resistance, high melting point, high temperature resistance, environmental protection, etc. Tungsten alloy is definitely a suitable crankshaft material.

Usually tungsten alloy parts are often used as counterweights for machines, boats, airplanes, yachts, spaceships, and other places that require small size and heavy weight. Tungsten alloys are widely used in high-performance engines (cars, racing cars, motorcycles, trucks) , yachts, etc.).

Tungsten alloy ring is generally used in industrial counterweights, or shields for medical devices. The thickness of the ring can be as thin as 2mm, but because it is too thin, it is prone to cracking during processing, so the rejection rate is high. The thinner the wall thickness, the higher the price.
