Tungsten Alloy Balance for Aircraft

Tungsten alloy balance for aircraft has high density and small volume, good abrasion resistance and good corrosion resistance. It can ensure that the aircraft has good stability, balance and maneuverability.

tungsten alloy balance for aircraft pictureIn addition to generating enough lift to balance gravity, having enough thrust to overcome resistance, and having good flight performance, an aircraft must have good stability and maneuverability to fly in the air. Otherwise, the balance, stability, and handling characteristics of the aircraft are not good, it will require a lot of effort on the part of the pilot to correct them. Therefore, for an aircraft with good performance, it is not only required to have high speed, fast climbing, height limit and long distance, but also its balance stability is also important.
