Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.
Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.
Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.
Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.
Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.
Affected by the ever-changing international situation, the supply and prices of international bulk Al-Si alloy are still very uncertain.
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.
