铝合金是一种优异的材料，常常用作电子元器件的外壳使用，而电子元件发热量较大，因此对于铝合金有较高的导热和刚性要求。但是现有的铝合金导热率通常在100-160W/m·K之间，而且为了保证导热性，通常是以牺牲其刚性为代价，因此需要一种铝合金保持高导热率进行散热的同时保证期刚性。Aluminum alloy is an excellent material, which is often used as the shell of electronic components, and electronic components generate a large amount of heat, so aluminum alloys have higher thermal conductivity and rigidity requirements. However, the thermal conductivity of existing aluminum alloys is usually between 100-160W/m·K, and in order to ensure thermal conductivity, it is usually at the expense of its rigidity. Therefore, an aluminum alloy is required to maintain high thermal conductivity for heat dissipation while ensuring Period rigidity.
