Magnetron sputtering high-purity aluminum AlIt has played a very important role in today's application fields. Advanced Institute Technology will conduct in-depth analysis from multiple dimensions, citing data and examples to support this viewpoint.
1、 Lightweight and easily recognizable characteristics
Aluminum is a lightweight metal with a density of only about one-third that of steel, which makes aluminum parts lightweight and easy to identify. Its low density is due to the much lighter atomic nuclei of aluminum, and the difference in unit cell size cannot compensate for this difference. Aluminum is one of the metals with the lowest density to date, and only alkali and alkaline earth metals with high reactivity that cannot be used in structures can have a lower density than it.
For example, the modern aerospace industry has a very high demand for lightweight materials, and aluminum happens to have the characteristics of being lightweight and easy to identify, and is widely used in fields such as aircraft and spacecraft. The low density of aluminum brings lighter components and can significantly reduce overall weight, improve aircraft fuel efficiency and load capacity.
2、 The combination of strength and durability
Pure aluminum is relatively soft and loses its tensile strength at around 300 ℃, while its melting point is high, reaching 660.4 degrees. However, processed aluminum alloys are more tough and easily ductile. Aluminum alloy has higher strength and hardness, and compared to pure aluminum, it has better durability. The yield strength of pure aluminum is 7-11MPa, while the yield strength of aluminum alloy can reach 200-600MPa.
For example, aluminum alloys are widely used in the automotive industry. The strength of aluminum alloy can meet the requirements of automotive components, and due to its relatively light weight, it can reduce the overall weight of the vehicle, improve fuel efficiency, and increase vehicle stability and safety.
3、 Good electrical and thermal conductivity
Aluminum has good electrical and thermal conductivity, with a conductivity and thermal conductivity of 59% that of copper, but its density is much lighter than copper. In addition, aluminum can superconducting at temperatures below 1.2K and magnetic flux greater than 100 Gauss, and is paramagnetic, basically unaffected by static magnetic fields.
For example, aluminum is widely used in the electronics industry as a thermal conductive material and circuit board. The thermal conductivity of aluminum makes it an ideal choice for heat sinks, which can efficiently conduct and disperse heat, protecting electronic components from overheating and damage. In addition, the conductivity of aluminum makes it an important material for wires and cables, which can effectively transmit current and signals.
in summary,
Magnetron sputtering high-purity aluminum AlPlays an important role in various fields. Its lightweight and easy to identify, combination of strength and durability, and good electrical and thermal conductivity make it an indispensable material in industries such as aerospace, automotive, and electronics. The application of aluminum is constantly expanding, bringing more convenience and development opportunities to people.
