In Part 2 of this series we dig deeper into the specifics of laterites, one of the two main nickel ore types and look at smelting, the most common processing technique.
Heather Allain, Executive Director, Materials Technology Institute (MTI), tells us about her passion for materials and the importance of MTI’s work to provide awareness of safe, reliable and sustainable materials use.
Let's dive into this new series of articles on sustainability, treatment processes and innovations in nickel production, starting with nickel ores.
China’s annual “two sessions” gives an indication of China’s broad policy direction for the year, covering topics from the economy to industrial strategy to environmental protection. David Chen explains the highlights, and the implications for the nickel value chain.
Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
What is a “sustainable product”? Is it more sustainable to continue using my old washing machine or to buy a new, more energy efficient one? Are single use products always unsustainable? What criteria should I use to judge whether a product is sustainable or not? What measures can we take to promote sustainability in products?
Each family of stainless steels has its strengths and weaknesses. Ferritic stainless steels have useful properties – a lower rate of thermal expansion, higher thermal conductivity, strong ferromagnetism and very high resistance to chloride stress corrosion cracking (SCC). When looking at selecting any alloys, it is important to consider all the factors for successful usage.
Awareness about robustness and durability of bridge design has grown since Morandi’s time. The new San Giorgio Bridge (its successor) in Genoa was designed by Renzo Piano and inaugurated in 2020.
The duplex alloys are “problem-solving alloys” for good reason, they have been successfully used in many places where carbon steels and standard austenitic alloys have failed. Just like with the austenitic family, there are many different duplex alloys to choose from, with corrosion resistance varying from moderate with the lean duplex alloys to very high with the superduplex alloys.
The selection of an alloy should be guided by careful examination of the needs of the application. Before making a switch, it’s important to fully investigate an alloy’s strengths, weaknesses and applicability to your structure.
In 2021, China recorded the strongest growth in the EV market with around 3.2 million EVs sold. This was an increase of 2 million EV units compared to 2020 which was more than the combined increase of all other regions taken together.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
Major economies across the globe are setting climate neutrality targets. But proper measurement and methodologies are needed to provide transparency and common benchmarks when assessing carbon footprint. At a recent event in China, there was general consensus on the importance of adopting a harmonized approach to carbon footprint calculation and disclosure.
While it may require an initial higher investment when compared with other materials, stainless steel’s unique properties deliver long-term performance and economic benefits including minimum downtime, reduced maintenance costs and reduced environmental impacts.
A new generation of designers, materials specifiers, architects and engineers is being introduced to the wealth of technical information curated by the Nickel Institute. An archive of technical guides and know-how for working with nickel-containing materials, including stainless steel, that has been built over thirty years is now being updated and made freely available.
The last three months have been unprecedented. But amidst the chaos and despite the drop in global GDP, there has still been a considerable amount of activity in the electric vehicle (EV) and battery world.
New energy legislation is set to optimize China’s energy structure and boost the use of non-fossil energy. Aligning with China’s regulatory agenda, nickel will play a vital role in tomorrow’s world powered by cleaner energy.
Around two-thirds of today’s buildings will still be around in 2050, and by 2060, the world is projected to add 230 billion m² of buildings - an area equivalent to the entire current global building stock. What can the building and construction sector do to reduce the environmental burden of buildings?
European nickel producers need a consistent regulatory framework. There must be coherence between different EU policy objectives with rules based on principles of sound science, risk-based approaches, full life-cycle thinking and impact assessments.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
Should we be worried about there being enough nickel to supply the transition to electric vehicles and cleaner energy sources? Given its wide range of uses in important existing and emerging technologies, this is a frequently asked question.
