Forgings refer to products manufactured by the process of shaping metal utilizing compressive forces. The compressive forces used are generally delivered via pressing, pounding, or squeezing under great pressure. Although there are many different kinds of forging processes available, they can be grouped into three main classes:
Forging produces pieces that are stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, the internal grain deforms to follow the general shape of the part. This results in a grain that is continuous throughout the part, resulting in its high strength characteristics. Titanium forgings are broadly classified as either cold, warm or hot forgings, according to the temperature at which the processing is performed.
Iron and steel are nearly always hot forged, which prevents the work hardening that would result from cold forging. Work hardening increases the difficulty of performing secondary machining operations on the metal pieces. When work hardening is desired, other methods of hardening, most notably heat treating, may be applied to the piece. Alloys such as aluminum and titanium that are amenable to precipitation hardening can be hot forged, followed by hardening. Because of their high strength, forgings are almost always used where reliability and human safety are critical such as in the aerospace, automotive, ship building, oil drilling, engine and petrochemical industries.

AmeriTi Manufacturing produces titanium powder using the hydride-dehydride (HDH) process. This method uses hydrogen to make the titanium brittle enough to crush and perform initial sizing. Hydrogen is then removed under vacuum followed by final sizing to customer specifications. This process creates a final particle morphology described as blocky or angular.
AMC also has the capability to deoxidize titanium alloy powders. Titanium is extremely reactive with oxygen causing it to inevitably increase in oxygen throughout the powder manufacturing process. Our patented deoxidation process allows for possible oxygen levels below 1000 PPM, which is necessary for grades such as Ti 6Al-4V ELI. Deoxidation services are performed on AmeriTi produced titanium powder, but is also available as a toll processing service.
Using this process, AmeriTi is able to produce both commercially pure and alloyed titanium powder in a wide range of particle sizes. Screening and blending processes ensure accurate sizing to customer specifications. Advanced process controls and in-process testing allow for consistent particle size distributions and morphology from lot to lot.
Titanium is the ninth most abundant metal available on earth’s crust; it is present in most igneous rocks and their sediments. Some of the minerals of titanium are illemenite, rutile, brookite, titanite and anatase. These minerals are primarily distributed in West Australia, Canada, Norway and Ukraine. It is low in toxicity, but the powder form of titanium is an explosion hazard.
Applications
The following are the application areas of titanium:
Pigments, additives and coatings
Aerospace and marine
Industrial
Consumer and architecture
Jewellery
Medical
Nuclear waste storage
Bike frames aren’t made from pure titanium. Instead, they are made from a titanium alloy. The titanium used to build bicycle frames is typically alloyed with aluminum and vanadium. Varying levels of each element are used to change the physical properties of the finished alloy. Alloying titanium improves strength and durability and reduces the weight of the frame. Many framebuilders market their titanium tubing as ‘aerospace-grade’.
