Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.
The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.
In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.
The volatile international situations will continue to affect the markets and prices of many commodities like the Al-Si alloy.
What is Aluminium-Silicon Alloy?
Silicon-aluminum alloy is a binary alloy composed of silicon and aluminum, which can maintain the excellent properties of silicon and aluminum respectively.
Silicon is good in metal alloys used for casting. Because it increases the fluidity of the melt, reduces the melting temperature, reduces the shrinkage associated with solidification, and is very cheap as a raw material. Silicon also has a low density (2.34g/cm3), which may be an advantage in reducing the total weight of casting parts. The solubility of silicon in aluminum is very low; therefore, it precipitates in the form of almost pure silicon, which is very hard, thus improving wear resistance. The content of silicon and aluminum is quite rich, and the preparation technology of silicon powder is mature and the cost is low; in addition, this material has no pollution to the environment and is harmless to the human body.
The density of Si-Al alloy is between 2.4g/cm3 and 2.7g/cm3, and the coefficient of thermal expansion (CTE) is between 7-20ppm/℃. The density and thermal expansion coefficient of Si-Al alloy decrease significantly with the increase of silicon content. At the same time, Si-Al alloy also has excellent properties such as good thermal conductivity, high specific strength and stiffness, good coating with gold, silver, copper and nickel, weldable with substrate, easy precision machining and so on.
Silicon-aluminum alloy is a promising electronic packaging material, especially in high-tech fields such as aerospace, space technology and portable electronic devices.
What Kinds of Silicon-Aluminum Alloys are Available?
The important silicon-aluminum alloy in industry can be divided into four categories:
Hypoeutectic silicon aluminum alloy. The silicon content is between 9% and 12%.
Eutectic silicon aluminum alloy. The silicon content is 11% to 13%.
Hypereutectic silicon aluminum alloy. The silicon content is 15% to 20%.
High silicon aluminum alloy. The content of silicon is more than 22%, mainly 25-70%, up to 80%.
What is Aluminium-Silicon Alloy Used For?
High silicon-aluminum alloy material has excellent tribological properties and can be used as an advanced lightweight wear-resistant material for all kinds of transportation tools, power machinery, machine tools and special fasteners.
High silicon-aluminum alloy is widely used as cylinder liner, piston, rotor and brake disc of automobile engine because of its low specific gravity, light weight, good thermal conductivity, low thermal expansion coefficient, volume stability, wear resistance, corrosion resistance and so on.
It can also be used for high power integrated circuit packaging.
Heat sink parts.
Al-Si alloy is a strong compound deoxidizer. Replacing pure aluminum in the steelmaking process can improve the utilization rate of deoxidizer, purify molten steel and improve the quality of steel.
What Series is an Aluminium Silicon Alloy?
What is Silumin?
Silumin is a group of lightweight and high strength aluminum alloys based on aluminum-silicon system. Aluminum-silicon alloys usually contain 3% to 25% silicon. Casting is the main use of Al-Si alloys, but they can also be used in rapid solidification process and powder metallurgy. Alloys used in powder metallurgy rather than casting may contain more silicon, up to 50%. Silumin has high corrosion resistance, making it suitable for wet environments.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the Al-Si alloy is erratic and thus its prices are expected to go higher in the future.
