Make Right Selection of Titanium and Its Alloys

in Titanium

For any kind of application an engineer need to consider both the aspects of technological and economical justification to make the proper utilization of titanium and its alloys. Since there is no doubt in the fact that the cost of this element is decrease with the increasing production and the improvement of processing, rather than to consider the technological justification needed for the right utilization of the titanium and it’s alloys.

Various applications are there for which this material is used. Even use of premium titanium for military and civilian is justifiable with cost, however for other items its cost is compensated for either by its advantages of increasing the lifespan of the application because of high corrosion resistance or by weight reduction due to its low density. In order to make right selection of titanium and its alloys there are two basic considerations which need to be appreciated, one is the specification of the component and other is its design.

Specification of any component requires to meeting the mechanical properties at the end including strength, hardness, bend ductility, elongation, area reduction, elevated temperature property and creep. It’s the product engineer’s responsibility to consider all the required specification and designing aspects of the material to produce the desired end product. In this article we mainly discuss how you can select right titanium and its alloy for your project.

If you are looking for good purity unalloyed titanium then formed, joined, cast and machined is better as compared with alloy grades. In this regard, the selection should be made on the basis of the desired properties required in the end item and must be satisfied by the employment of unalloyed titanium grades. The unalloyed grades offered by commercial producers have considerable variation in properties even sometimes the variation has been noticed with the same producers in the terms of heats of the same grade titanium.

With the improvement in production process and melting techniques, greater co-relation can be expected and in the last few decades many significant improvements has been made in this direction. To ensure the material used will not exceed the maximum tolerable limits, the engineer should familiarize himself with the specification of the metal. It’s necessary to consider the alloy grade of titanium where specific applications ask for special alloying elements or wherever higher strengths are required. Remember the increment of alloy content can increase its strength with the accompanying ductility loss.

There are various material used for titanium casting such as Manganese, Chromium binaries and Aluminum. However aluminum containing multi component has the major advantage for better elevated temperature properties and hence it is the most useful titanium materials in the industry. Generally it is advisable to use unalloyed titanium and wherever required or possible heat treatment should be employed to gain the best ductility in the end product.
