tungsten alloy counterweight for aircraft manufacture process

tungsten alloycounterweight for aircraft is made of high-density tungsten alloy material; its main manufacture process includes mixing, pressing, sintering, post-processing and final machining. Raw material for tungsten alloy counterweight for aircraft is mainly selected based on particle size of tungsten powder. The same particle size helps to blend evenly, which ensures the density and properties for finished part uniformly. During sintering process, parts will be moved into the sintering furnace, temperature control is the most important thing.

Tungsten alloy counterweighs are not formed by a single element, but by a mixture of a variety of elements, including nickel, iron, copper, etc. After mixing and pressing, tungsten alloy material forms into the basic shape, and then after sintering and heat treatment process, tungsten alloy parts achieve the required blank product with high density and properties requirements, however, if there is a surface requirement, it needs to be final machined. More than 90% the proportion for other elements just works as a binder.
