After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people's concerns for supply shortage eased.
At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper.
Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc Graphite Lubricant are still very uncertain.
There are many types of lubricants available, from motor oils to special lubricants such as lithium-based lubricants. Some modern materials can be impregnated with lubricants, thus eliminating the need to lubricate moving parts. Graphite lubricants are unusual in that they can be used both as dry lubricants and as liquid bases.
Uses of lubricants
Lubricants reduce the friction between two surfaces. When the friction between two surfaces is too great, they may not be able to move. By adding lubricants, mechanical systems are less susceptible to friction-related problems. One of these problems is heat. Components that rub against each other without a lubricant will generate more heat than components that reduce friction through lubrication.
What is graphite?
Graphite is a form of carbon. Graphite is silvery black in colour with a dull metallic sheen. Graphite is a very soft mineral. On the Mohs hardness scale, it lies between 1 and 2. Due to this softness and its tendency to flake, it is ideally suited for use as a dry lubricant.
Graphite as a dry lubricant requires contact with the atmosphere for optimum performance. The water vapour in the air reduces the molecular bonding of graphite, allowing it to slide and thus reduce friction. The disadvantage of graphite as a lubricant is that it does not bind well to the surface it is lubricating. It comes off easily and needs to be applied frequently.
There are different types of liquid graphite lubricants. One type is graphite suspended in a liquid matrix which evaporates when the liquid is applied to the surface. When the liquid evaporates, a thin layer of pure graphite is left to lubricate the surface. Graphite grease is a graphite lubricant designed to adhere to a surface, for example when used on exposed bearings. The grease will help to keep the graphite in place and allow it to work.
Advantages of graphite
Graphite has advantages in situations where wet lubricants may not be practical, for example where electricity may be at risk. Another situation is when lubricating porous substances such as wood. Wood can be easily soiled by oil or other common lubricants. Compared to some other lubricants, graphite can dissipate more heat. For example, graphite greases can often handle more heat than natural bearing greases.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the Graphite Lubricant will be influenced by that.
