The combination of tensile strength, rigidity and a high temperature tolerance are three of the most important factors in the design of any aircraft. Unfortunately, some of the most common metals such as iron, steel or aluminium are simply too weak to withstand the vigorous demands that are placed upon them. For example, simple metals will hardly be able to stand up to the profound temperature variations that can be encountered at different altitudes or inside of turbofan engines. Expansion and contraction rates will likewise differ; perhaps resulting in a structural failure that can be catastrophic in nature. Simpler metals are also not as resistant to corrosion as are highly exacting alloy mixtures. These are some of the primary reasons why such objects as the Inconel 718 tube have proven themselves to be essential in the world of 21st century engineering. So, let’s take a look at some of the characteristics of this type of tube.
Some of the Key Characteristics of this Tube
As mentioned previously, one of the most important aspects in regards to this tube to note is the fact that as opposed to being comprised of a single metal, it is instead a proprietary blend of different substances. Some of these such as columbium and niobium may actually be relatively unfamiliar to most individuals. These and other elements are found in very exacting percentages in this tube and the advantages that engineers can enjoy are indeed worth mentioning. Some of the primary benefits of this substance are:
- An excellent weldability
- High rupture strength (excellent for expansion joints and fasteners)
- High impact strength (required for the blades of a turbofan engine, for example).
- A wide range of temperature applications.
While this type of tubing is used in considerable quantities throughout a plane, it is also worthwhile mentioning that a variety of lengths and widths are available. This allows the Inconel 718 tube Sterling Aircraft Materials to be a highly versatile piece of equipment.
As should be expected, there are a number of retailers and online suppliers that offer standard forms of this tube. However, there may be times when a very specific length or cut is required. Many online suppliers can match this tubing to the exact specifications that are required. These are some of the most important benefits that are associated with the 718 series of tubing. Obviously, it is always a good idea to shop around between different suppliers. Comparing and contrasting offers will enable one to find the best pricing available on the marketplace.
