According to insider sources, China’s leading nickel producer, Qingshan Group, has commenced commercial nickel refining production in Indonesia. The factory is located in Morowali, Indonesia, with a planned annual capacity of 50,000 tons and has recently initiated commercial production. While the actual production capacity of the factory and the timeline to reach the 50,000-ton target […]

Austenitic stainless steel, composed of chromium and nickel, is prone to a type of corrosion called intergranular corrosion when heated in the temperature range of 450 to 800°C. This phenomenon occurs along the grain boundaries. Intergranular corrosion is commonly attributed to the precipitation of Cr23C6 in the form of carbon, leading to chromium depletion in

Black metals include: iron, manganese, chromium, vanadium, titanium. Non-ferrous metals include: copper, lead, zinc, cobalt, nickel, tungsten, tin, molybdenum, bismuth, mercury, antimony. Light metal minerals include: aluminum, magnesium. Precious metal minerals include: gold, silver, platinum group metals (platinum, palladium, rhodium, iridium, ruthenium, osmium). Rare and rare earth metal minerals include: tantalum, niobium, beryllium, lithium, zirconium,

Compared to stainless steel used in industrial structures, medical-grade stainless steel is required to maintain excellent corrosion resistance within the human body. This requirement aims to minimize the release of metal ions, prevent occurrences of localized corrosion such as intergranular corrosion and stress corrosion, and avoid potential failures and fractures of implanted devices. Ensuring the

Stainless steel, with its advantages of “corrosion resistance, durability, and environmental friendliness,” has won people’s hearts. However, its application has been greatly restricted due to its cold and monotonous appearance. Colored stainless steel has emerged to address this limitation. It not only maintains the physical, chemical, and mechanical properties of traditional stainless steel but also

Steel is a black metal, not a non-ferrous metal. Based on characteristics such as color and properties, metals are classified into two main categories: ferrous metals and non-ferrous metals. Ferrous metals primarily include iron, manganese, chromium, and their alloys, such as steel, pig iron, iron alloys, and cast iron. Metals other than ferrous metals are

Nickel is the primary alloying element for forming austenite, but its effects are fully realized only when combined with chromium. If nickel is used alone, to achieve a pure austenitic single-phase structure in low-carbon nickel steel, the nickel content needs to be above 24%. In fact, the nickel content needs to reach 27% to significantly

Nickel is a ferromagnetic element, ranking as the fifth most abundant element on Earth after silicon, oxygen, iron, and magnesium. It has the highest concentration in the Earth’s core, where it exists as a natural nickel-iron alloy. In the Earth’s crust, nickel is more abundant in ferromagnesian rocks compared to silicic rocks. For instance, olivine-rich

Nickel is extensively used across various industries, with its most popular applications being in the stainless steel and electric vehicle (EV) battery production sectors. The most common use of nickel is in stainless steel production, where over 66% of the global nickel ore is utilized for manufacturing stainless steel used in kitchen equipment, chemical processing,

Changjiang Aluminum (alu.ccmn.cn) Commentary: The stock market and crude oil collectively declined as risk aversion dominated. Overnight, London aluminum fell by 1.91%. The overseas macro atmosphere shifted to bearish, while Yunnan’s electrolytic aluminum capacity continued to release, leading downstream buyers to adopt a cautious and price-pressured procurement approach. Today, aluminum prices are expected to decline.
