Appeal or performance? Alloy versus steel rims
Rims play a big role in appeal of a car and so distinct – shiny ones in this case – contribute a fraction to a car’s resale value.Vehicles either have steel or alloy rims. The obsession with rims is actually more pronounced among youthful car enthusiast who for reasons subscribe to the high-octane life and so appeal is a key element. Rims play a big role in the appeal of a car and so distinct – shiny ones in this case – contribute a fraction to a car’s resale value. Brand new cars are with rims are priced differently.However, both steel and alloy have advantages and shortcomings depending on what a car owner is looking for. But first, wheels and rims are most times used to mean the same thing but they are technically not. A wheel is a part that has the hub and spoke while a rim is an outer part that holds the tyre.PerformanceFor cars that are to be used for transporting goods, fieldwork and saving fuel and ensuring a tight tyre to rim grip in high speeds, Owere argues that alloy i...

Is there a meteoric market rise for scandium next?
It is extremely rare to find a metal where the potential demand is much greater than what anyone can supply. It has happened the past year with the emissions metals palladium and rhodium which were up 75% and 366%; so it makes good sense that scandium may be next.Scandium-Aluminum alloy is a key material in the lightweighting industryLightweighting of vehicles is a massive new trend this decade as we switch over to electric vehicles. Just 2% scandium added to aluminum increases strength, heat tolerance, corrosion resistance, and weldability. A lighter vehicle will require less energy (less gasoline or less lithium-ion batteries) to move a set distance.Scandium offers improvements in aluminum particularly suited to the transport sector; marine, automotive, and aerospace.Scandium’s place in lightweighting is on the rise which means the need for new scandium mines has never been greater. Whilst still a niche industry with a high scandium metal price, if a min...

China boosts Indian alloy exports, zorba prices
Indian exports of unwrought aluminum alloy to China surged in the last two months of 2019 as the country provided ADC12 to Chinese diecasters normally supplied by domestic smelters, leading to a surge in feedstock zorba scrap prices to India.China imported 3,600t of aluminum alloy from India in December, up from none the prior year, according to China Customs. November imports were up to 1,400t, also from none the prior year. October imports were 85t, up from zero as well.China's aluminum alloy imports spiked to 63,000t in December, doubling the November total and nearly eclipsing the full-year 2018 total of 74,000t. Full-year 2019 imports of alloy reached 216,000t, the highest since 2009.Meanwhile, China's imports of aluminum scrap dropped to a 15-year low of 1.4mn t in 2019, down by 11pc from 2018.Following strict government-imposed scrap import quotas in late 2019, China was unable to meet its demand for secondary aluminum alloy and turned to imports from India, Asia, Europe, the Mi...

Making new catalysts from unique metallic alloys
Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ability to regain their original shape after being deformed, known as shape memory. Investigations by Tohoku University's advanced materials scientist An-Pang Tsai and colleagues now show that these materials can also be fine-tuned to speed up chemical reactions. Heusler alloys have a typical composition of two parts metal X, one part metal Y, and one part metal Z (X2YZ). Each of the three come from a distinct region of the periodic table of elements. The original Heusler alloy, discovered in 1898, was Cu2MnAl, made from copper, manganese and aluminium. Many other combinations of metals were later found within the X2YZ arrangement.While Tsai and his colleagues were investigating another type of structure, called quasicrystals, in the late 1980s, they created a series of new compo...

Ultrasound can make stronger 3-D-printed alloys
3D printed Titanium alloys under an electron microscope: sample on the left with large, elongated crystals was printed conventionally, while sample on the right with finer, shorter crystals was printed sitting on a ultrasonic generator. Credit: RMIT UniversityResearchers have used sound vibrations to shake metal alloy grains into tighter formation during 3-D printing.A study can have a significant impact on the inner micro-structure of 3-D printed alloys, making them more consistent and stronger than those printed conventionally.Lead author and Ph.D. candidate from RMIT University's School of Engineering, Carmelo Todaro, said the promising results could inspire new forms of additive manufacturing.'If you look at the microscopic structure of 3-D printed alloys, they're often made up of large and elongated crystals,' Todaro explained.'This can make them less acceptable for engineering applications due to their lower mechanical performance and increased tendency to crack during&...

For stronger 3D-printed titanium alloys – just add copper?
The ability to 3D print titanium-alloy objects certainly does open up some intriguing possibilities. That said, the finished items aren't always as strong as they could be. Now, new research suggests that adding copper to those alloys could make a big difference.Typically, when objects are being 3D printed out of titanium alloy, a laser is used to selectively melt a powder consisting of titanium particles and other chemical elements. In this fashion, items are built up a layer at a time, as each layer of melted powder cools into a solid.According to scientists at Australia's RMIT University, however, problematic column-shaped crystals form within the material as it cools and bonds. These ultimately make the end product more prone to cracking and distortion.And unfortunately – unlike the case with some other metals – there are no commercially-available grain-refining compounds that can be used with titanium alloys, in order to address the problem.Working with colleagues f...
