When machining parts for Aerospace CNC Machining applications, there are many factors to consider, such as the part's shape, weight and durability. These factors will affect the flight value of the aircraft. For many years, the material of choice for aerospace applications has been aluminum alloys. However, in modern jet aircraft, it accounts for only 20% of the structure.
However, the use of composite materials such as carbon-reinforced polymers and honeycombs is increasing in the modern aerospace industry due to the demand for lightweight aircraft. In recent years, aerospace manufacturers have begun researching alternatives to aluminum alloys, one of which is aircraft-grade stainless steel. The use of this stainless steel in new aircraft components has increased. This article will explain the uses and differences between aluminum alloys and stainless steel in modern aircraft.
Aerospace CNC Machining aluminum alloy parts for applications
Aluminum is a relatively light material, weighing approximately 2.7 g/cm3 (grams per cubic centimeter). Although aluminum is lighter and less expensive than stainless steel, it is not as strong and resistant to corrosion as stainless steel. Stainless steel is superior to aluminum when it comes to durability and strength.
Although the use of aluminum alloys has declined in many aspects of Aerospace CNC Machining production, aluminum alloys are still widely used in modern aircraft. Aluminum remains a strong, lightweight material for many specific uses. Due to its high ductility, it is easy to process and is relatively inexpensive compared to many composite materials or titanium. It can also be further strengthened by alloying it with other metals such as copper, magnesium, manganese and zinc or by cold or heat treatment. When aluminum is exposed to air, tight chemical oxidation bonds isolate the aluminum from the environment. This feature makes it extremely corrosion-resistant.
