Aeroplane Manufacturing

Airplanes have to meet a number of demands that no other vehicle has to deal with. A car, for example, is supported by wheels and does not have to exceed 120 kilometers per hour. It is made mostly with steel, and an increasing number of parts are made with aluminum and even plastic. The reason for the change is not to endure harsh conditions but simply to save on petrol. There are many aerospace metals uk manufacturers choose to buy.

Airplanes have to meet very specific conditions, particularly if they are intended to exceed the speed of sound. They must be lightweight and yet strong. This means that metals such as aluminum and titanium are extremely important. As the airplane goes faster, a more expensive mixture of metal is typically used.

Airplanes have traditionally been made with steel plates and either steel or aluminum frames. Steel can be strong when formed into a skeleton with bars that have metal removed at points of least stress. While this is sufficient for rotary aircraft, faster aircraft might have problems with weight and vibration. Steel is still used in airplanes, but it tends to be a very high strength steel. This means a super alloy that combines iron with exotic metals and has the strength necessary to skimp on metal.

Aluminum has been used in aircraft for decades, and it is still important. It is strong when made with the right alloy, and it melts at a relatively low temperature. Aluminum can be cast into a wide variety of shapes inexpensively. The only way to achieve a similar shape with steel or titanium would be to shape it in a shop with diamond drills, a much more expensive process. Aluminum might be used in the body of the aircraft and the skin.

Titanium is very strong, half the weight of steel, and melts at a high temperature. Titanium is useful in constructing engine components. It is also used for the skin of high-speed aircraft. Because military aircraft must break the sound barrier, they must deal with shock and the heat of air friction. Titanium can endure the stress better than a weaker metal. It is too expensive to use excessively.

An unusual metal for airplanes includes tungsten alloys. tungsten has a high strength and a high melting point. It is also heavier than lead. It can be used to help balance the aircraft and be used in devices that sense directional change. Aircraft need to be properly balanced in order to be efficient, and weights are added to offset asymmetrical systems components and added loads.
