Aerospace fasteners different role explanation

Aerospace fasteners using a variety of standard fasteners include screws, rivets, bolts, pins and washers, the key difference is "quality". In order to withstand high pressure and high temperature environments (such as leaving the Earth's atmosphere or environment exposed to rocket fuel combustion), aerospace products require a higher degree of durability. In addition, aerospace product weight have to be "light". This can help the body take off or reduce the rocket's fuel costs. Aluminium-aluminium applications in the aerospace industry does not play an important role, but on the light weight of aluminum used in the body. However, this material may require additional processing. For example, aluminium rivets are very common, but the aluminum itself must be cold-forged head. Common alloy used in aerospace fasteners is: 1100, 2117T, 2017T-HD, 2024T, 5056T and 7075T. Steel-the steel is quite tough and hard alloy, weight is also very heavy, which may make its use led to some problems in air vehicle. Mainly used in aerospace steel style stainless steel and alloy steel. Specific species are vulnerable to heat damage or failure of stainless steel, so choosing the right kind of stainless steel is a priority.
