铝板牌号指南: 1060, 3003, 5052, 6061, 5083, 7075 解释
铝板有多种等级可供选择, and choosing the right one determines the strength, 耐腐蚀性能, weldability and cost of your project. This guide explains the six most common aluminum plate grades – 1060, 3003, 5052, 6061, 5083 和 7075 – covering their chemical composition, mechanical properties and typical applications, so you can quickly identify which grade suits your use.
Aluminum Plate Grades at a Glance
| 年级 | Series | Key alloying elements | 力量 | Corrosion resistance | Typical applications |
|---|---|---|---|---|---|
| 1060 | 1xxx | 99.6% 铝 (pure) | Low | 出色的 | Electrical conductors, chemical tanks, 装饰板 |
| 3003 | 3xxx | 锰 | Low – 中等的 | 好的 | 屋顶, 炊具, 热交换器, general sheet metal |
| 5052 | 5xxx | 镁 | Medium | 出色的 (海军陆战队) | 船用零件, fuel tanks, pressure vessels |
| 6061 | 6xxx | 镁 + 硅 | 高的 (T6) | 好的 | Structural frames, 汽车, 机械 |
| 5083 | 5xxx | 镁 + 锰 | 高的 | 出色的 (海军陆战队) | 造船, pressure vessels, offshore structures |
| 7075 | 7xxx | 锌 | 非常高 | 好的 | 航天, 模具, high-strength parts |
1060 铝板: Pure Aluminum for Conductivity
1060 belongs to the 1xxx series with a minimum aluminum content of 99.6%. It offers excellent electrical and thermal conductivity, outstanding corrosion resistance and good formability, but has low mechanical strength. It is widely used for electrical bus bars, chemical storage tanks, capacitor casings and decorative applications where purity matters more than strength.
3003 铝板: The Workhorse Alloy
3003 is strengthened by manganese and is the most widely used general-purpose aluminum alloy. It has moderate strength, 良好的成型性, excellent weldability and good corrosion resistance. Common uses include roofing and siding, cooking utensils, 热交换器, fuel tanks and general sheet metal work.
5052 铝板: Marine-Grade Corrosion Resistance
5052 is a magnesium alloy with the highest strength among non-heat-treatable grades. It provides excellent salt-water corrosion resistance, good fatigue strength and outstanding weldability, making it the preferred choice for marine applications, fuel tanks, pressure vessels, hydraulic tubes and appliance panels.
6061 铝板: Structural All-Rounder
6061 is a heat-treatable aluminum-magnesium-silicon alloy. In the T6 temper it reaches a tensile strength of about 290 兆帕, combining high strength with good weldability, machinability and corrosion resistance. It is widely used for structural frames, truck bodies, 机械零件, bicycle components and general fabrication.
5083 铝板: Shipbuilding Champion
5083 is a high-strength magnesium-manganese alloy specially developed for shipbuilding. It retains high strength after welding and offers the best combination of strength and corrosion resistance in marine environments. It is the standard grade for hull plates, offshore platforms, pressure vessels and cryogenic tanks.
7075 铝板: Aerospace-Grade Strength
7075 is strengthened with zinc and is one of the strongest aluminum alloys available, with a tensile strength exceeding 570 MPa in the T6 temper. It is used where maximum strength-to-weight ratio is required: aircraft structures, missile parts, high-performance molds, rock-climbing equipment and precision machinery.
How to Choose the Right Grade
- Need maximum corrosion resistance or purity? 选择 1060.
- Need a low-cost general-purpose alloy? 选择 3003.
- Working in marine or salt-water environments? 选择 5052 或者 5083.
- Need high strength with good weldability? Choose 6061-T6.
- Need the highest strength-to-weight ratio? Choose 7075-T6.
- Not sure? Send us your application details and our engineers will recommend the most cost-effective grade.
