Titanium Forgings

Titanium alloys are one of today’s most widely used alloy metals in various applications. Their main component is titanium, but, of course, they also contain certain amounts of other elements to enhance properties for metallurgical purposes.

A lightweight, metallic element, titanium is often compared to steel in terms of strength. Its pure form comes in two solid crystalline forms:

  • Alpha – this occurs at low temperatures and has a Hexagonal Closed Packed (or HCP) structure.
  • Beta – this occurs at high temperatures and has a Body Centered Cubic (or BCC) structure.

The Process Of Forging Titanium Alloys 

There are three major groups of titanium alloys:

  • Alpha or near alpha
  • Beta or near beta
  • Alpha plus beta

Generally, beta titanium alloys are quite easier to forge than alpha titanium alloys and alpha-plus-beta titanium alloys.

To breakdown titanium ingots, the initial forging temperatures should be set to higher levels than the intermediate forging and finish forging settings.

Because of the necessary process control, forging of titanium alloys can be a lot more difficult than aluminum and steel alloys. Forging temperatures have to be controlled and monitored to achieve the appropriate mechanical properties. The temperatures involved include the furnace setpoint, adiabetic heating, die chill, and heat loss.

At high strain rates and temperatures, titanium can soften very rapidly and can result to flow localizations. Because of this, defects such as a crack or lap can appear. So, forging titanium is preferred at lower strain rates to prevent these critical flaws.

Methods Of Titanium Forging 

Conventional titanium forging is performed at lower die temperatures, using less complicated and less expensive tools.

In iso-thermal titanium forging, on the other hand, the raw materials and forging dies are set to very high levels, a condition known as “iso-thermal,” accompanied with close monitoring and tolerance, special lubricants, super alloy tooling and equipment, and forging pressures and speed tracking.

Titanium Forging Applications 

Because of superior attributes and properties, titanium forgings are used in several industries including:

  • Military and marine (propeller shafts, submarines, saltwater aquariums)
  • Aerospace (airframes, wing structures)
  • Outdoor activities (knives, hunting tools, camping)

Titanium Forgings

Titanium Forgings and CastingsTitanium forgings are standard forged pieces which we produce for both our domestic and overseas titanium customers. We have a full inventory of standard casts and molds for rings, targets and disks and also offer bespoke part titanium forging and titanium castings for engineered designs. Our machinery is capable of accommodating titanium forgings and castings from the smallest bone support structure to large aircraft landing gear shape. We have invested heavily in our forging machinery and have a range or hydraulic forging machines from 1500 to 4000 tonnes. We also have a number of highly skilled individuals who are highly regarded in the field.

Standard Forged Parts

The following specification details our standard titanium forged parts specification. These are titanium rings and titanium discs. As well as standardized products we produce to bespoke designs which are based on customer designs and through collaboration with our experienced titanium engineers.

About Our Forgings

Our main forged products include titanium axles, forged rings and titanium disks. Our overseas customers are located in Poland, Romania, Germany and the United States.

Our standardized forging and casting products are titanium discs and titanium rings. For all other specialist designs we follow a stepwise approach to ensuring the titanium forged part is correct and meets all requirements. After agreeing a design with engineers from both parties we produce and test a mould which is used to produce a pilot part which is provided to customers for secondary testing and inspection. Upon agreement of the pilot piece the next step in the process is to produce the first batch of components and deliver. Finally we may also provide the mold a separate component as part of product deliverables.

Despite being an age old process it takes a great deal of skill and craftsmanship to produce titanium forgings and castings. We have over 30 years experience in the field and have handled a large number of differing parts. We are confident we can outperform any one on the market for engineering excellence, rapid production and low price.
