6061铝板和7075铝板的主要区别包括：

　　The main differences between 6061 aluminum plate and 7075 aluminum plate include:

　　成分不同 ：

　　Different components:

　　7075铝板属于7000系列，主要合金元素为锌，含量约为6%，还包含镁和铜。

　　7075 aluminum plate belongs to the 7000 series, with zinc as the main alloying element, accounting for about 6%, and also containing magnesium and copper.

　　6061铝板属于6000系列，主要合金元素为镁和硅，锌含量较低。

　　6061 aluminum plate belongs to the 6000 series, with magnesium and silicon as the main alloying elements and low zinc content.

　　机械性能不同 ：

　　Different mechanical properties:

　　7075铝板具有较高的强度和硬度，被称为超硬铝或航空铝，适用于要求高强度和韧性的应用场合。

　　7075 aluminum plate has high strength and hardness, known as ultra hard aluminum or aviation aluminum, and is suitable for applications that require high strength and toughness.

　　6061铝板强度和硬度适中，具有良好的可加工性、焊接性能和抗氧化性。

　　6061 aluminum plate has moderate strength and hardness, good processability, welding performance, and oxidation resistance.

　　应用领域不同 ：

　　Different application fields:

　　7075铝板常用于制造飞机结构、高应力结构件和模具制造等。

　　7075 aluminum plate is commonly used in the manufacturing of aircraft structures, high stress structural components, and mold manufacturing.

　　6061铝板适用于建筑、汽车、船舶、家具、机械零件等领域，需要一定的强度、可焊性和抗蚀性。

　　6061 aluminum plate is suitable for fields such as construction, automobiles, ships, furniture, mechanical parts, etc., and requires certain strength, weldability, and corrosion resistance.

　　价格不同 ：

　　Different prices:

　　由于7075铝板的制造成本较高，其价格通常高于6061铝板。

　　Due to the higher manufacturing cost of 7075 aluminum plate, its price is usually higher than 6061 aluminum plate.

　　需要注意的是，尽管7075铝板在强度和硬度上优于6061铝板，但6061铝板因其良好的综合性能，在更广泛的制造领域有着更普遍的应用。此外，7075铝板的焊接难度较高，而6061铝板则相对容易加工和成型

　　It should be noted that although 7075 aluminum plate is superior to 6061 aluminum plate in strength and hardness, 6061 aluminum plate has a more widespread application in a wider range of manufacturing fields due to its excellent comprehensive performance. In addition, the welding difficulty of 7075 aluminum plate is relatively high, while 6061 aluminum plate is relatively easy to process and form
