Can titanium be used as a cost-effective material to make bicycle frames for the average commuter? The superstrong metal has long been used for decades in the creation of high-end bikes that are used, mostly, by consumers willing to pay a premium for more costly materials and more difficult tooling.
The annual contest is an independent innovation platform for building the urban utility bike. In 2014, its organizers partnered high-level design firms with American bicycle craftsmen to collaboratively develop the next-wave urban bike. Five teams from five cycling-centric cities competed to concept, create and champion their unique vision of tomorrow’s bicycle for the everyday rider.
The journal Science reported that the new shape memory alloy shatters previous records for bending and is so resilient it could be useful in artificial heart valves, aircraft components or a new generation of solid-state refrigerators.

shape memory alloys (SMAs) are already used in surgical operations and other applications. A stent, for example, might be squashed into a small space and then spring into its designed shape to prop open a blood vessel.
The UK’s Aerospace Technology Institute (ATI) has agreed to invest £1.5 million ($2.3 million) in a collaborative R&D project, led by GKN Aerospace and Metalysis, the specialist metals technology company with partners Phoenix Scientific Industries Ltd. and The University of Leeds to develop the use of Metalysis’ high quality, low-cost titanium powder for use in aerospace additive manufacturing for the first time with a commercial partner.

In an interview with MetalMiner, Dr. Kartik Rao, Director of Business Development at Metalysis discussed the potential benefits for not just additive manufacturing as a technology but for the adoption of titanium 3D printed parts across a range of industries.
Reduction in Costs
The cost of the powder in 3D parts makes up roughly 50% of the final cost, Rao explained, so a significant reduction in powder costs could be a major spur to the adoption of such technology in more applications and in industries beyond aerospace and medical devices, such as automotive.
Investors would always like a better performance but in the midst of one of the most tumultuous periods in the history of the non-ferrous metals markets the firm has seen the writing on the wall and positioned themselves to take advantage of changes in their marketplace while minimizing the damage from market turmoil.
Alcoa’s latest move, as reported earlier in MetalMiner, to acquire, Pittsburgh-based RTI International Metals Inc., in a $1.5 billion stock for stock deal is a logical and sound strategic move, building on the aluminum producer’s long-term plan to invest in downstream, value-added activities and gradually move away from the lower-return primary smelting business. Alcoa has invested heavily in new production facilities to meet an inexorable rise in demand for automotive sheet and to capitalize on it’s position as a major player in the equally buoyant aerospace sector.
The purchase of the titanium specialist RTI Metals, with its focus on exactly the same markets but in the complimentary product area, will support Alcoa’s existing activities and allow it to grow its sales book with major automotive and aerospace firms.
Indian Rare Earths Limited operates under India’s Department of Atomic Energy. When complete, the new $82 million titanium plant joint venture with India’s NALCO (National Aluminum Company) will make 100,000 tons (1 lakh ton) of titanium slag in the eastern state of Odisha. Some of it will also be used to make pig-iron. A feasibility study and technology selection on the project will soon be carried out.
Incidentally, the MoU for formation of the joint-venture was signed between the two state-owned entities about three years ago but was revalidated last week. No explanation was forthcoming for the delay.
India’s state-owned National Aluminum Co Ltd (NALCO) has signed a Memorandum of Understanding (MoU) with another public sector company, Indian Rare Earths Ltd (IREL), to jointly set up a titanium slag plant.
That could be good news for India’s space program. Why? The project envisages adding value to Ilmenite, a titanium-iron oxide mineral, to produce the slag. Slag is an intermediate product for making titanium sponge and titanium pigments. Titanium sponge is a porous substance formed in the first stage of processing of the naturally available titanium. The latter is high strength but has low density properties, and is also corrosion-resistant. It’s widely used in the manufacture of aircraft, among other things. Titanium-alloy components are also used to make missiles and satellite launch vehicles.
Incidentally, just a few weeks ago, The Indian Space Research Organization (ISRO) launched five foreign satellites, marking an important milestone in its space program.
IREL operates under India’s Department of Atomic Energy. When complete, the plant will make 100,000 tons (1 lakh ton) of titanium slag in the eastern state of Odisha. Some of it will also be used to make pig-iron. A feasibility study and technology selection on the project will soon be carried out.
The plant is estimated to cost around $82 million (Rs 500 crore). The MoU for formation of the joint-venture had been signed between the two central public sector entities about three years ago but was revalidated last week. No explanation was given for the delay.
The author, Sohrab Darabshaw, contributes an Indian perspective on industrial metals markets to MetalMiner.
The deadlock between Ukraine and Russia – particularly over Crimea, the current battleground where the US and the EU have joined the fray – got us thinking, “Man, there must be some massive supply chain implications here.”
And there definitely are – for pricing, availability, lead times across a broad range of commodities, parts, components and finished products, far beyond the immediate region itself.
It is our view that the political front is the one to watch, as impending sanctions on Russia imposed by the US/EU would be the main catalyst for supply chain upheaval. On the non-metal commodity front:
According to JPMorgan Commodities Research analysts, although Ukraine is neither a major oil producer nor oil consumer, it is the key “middleman” country for Russian energy exports. More than 70 percent of Russia’s gas and oil flows to Europe pass through its territory. In turn, Europe is the buyer for nearly 90 percent of Russia’s oil exports.
If tension escalates, namely if military action is undertaken, pipelines could potentially be cut off and actual delays or shortages could hamper western (EU) supply.
On the metals front, several key US manufacturers’ supply chains could feel reverberations due to their business in Russia (especially if US/EU sanctions directly affect them). For example:
Boeing Co. buys nearly a third of its titanium for its planes (translating into an $18 million total spend) from Russia, mostly from VSMPO-Avisma, which is the largest titanium producer in the world, according to the WSJ.
If the supply chain is impeded in any way, the perception of “slow availability” could drive titanium prices to rise, even though Boeing’s long-term contracts with VSMPO-Avisma lock in price.
India has taken another step in the production of titanium sponge when the well-known public sector steel producer, the Steel Authority of India Limited (SAIL), signed an agreement with the Kerala State Industrial Development Corp (KSIDC) and Kerala Minerals and Metals Ltd (KMML) to jointly set up an approximately US $458 million plant to produce titanium sponge and metals, according to the Times of India.
Titanium sponge is a porous substance formed in the first stage of the processing of the naturally available titanium.
Titanium is known for its excellent corrosion resistance, high strength and low-density properties, which make it widely used in the manufacture of civilian and military aircraft. Titanium-alloy components are also used in satellite launch vehicles, rockets and missiles.
The Economist covered an industrial development in a recent article entitled “A Tantalising Prospect” that would catch the eye of anyone remotely interested in the metal industry.
The process described effectively allows the reduction of high-melting-point metal ores such as titanium, tantalum, and potentially other expensive metallic elements including neodymium, tungsten and vanadium, from the oxide to the metal in powder form.
The process is a type of electrolysis, but rather than hold the metal oxides in liquid form, it holds them as metal powders in a liquid salt at much lower temperatures and hence requires much lower energy inputs than would be the case if they were reduced in the liquid state.
