Unique Advantages of Aluminum alloy Materials
1. Good mechanical properties
Low density, light weight;
high strength, strong and durable;
good corrosion resistance, not easy to rust;
good thermal conductivity and electrical conductivity;
easy to process and shape, and can manufacture products of various complex shapes
2. Diverse processing techniques & rich appearance effects
Anodizing: Aluminum alloys are very suitable for anodizing.
Electroplating
Powder spraying/ Painting
Chemical conversion coating treatment
Grade of Aluminum
1000 series: The main component is pure aluminum, containing more than 99% aluminum. Eg Al1050,1060,1070
2000 series: With copper as the main alloy element, it has high strength and hardness, and the heat treatment strengthening effect is obvious. It is a hard aluminum alloy. However, the corrosion resistance is weak. Eg2040,2070
3000 series: The alloying element is mainly manganese, with good formability, corrosion resistance and weldability, and moderate strength.
Eg. 3003 aluminum alloy.
5000 series: Magnesium is the main alloy element. It has good seawater corrosion resistance, weldability and medium strength. Eg 5052, 5053
6000 series: The alloy elements are magnesium and silicon, with good comprehensive properties, medium strength, good corrosion resistance, weldability and anodizing properties, and easy to extrusion. 6000 series widely used in CNC Machining Industry. Eg. Al6060,AL6061,AL6063,AL6082
7000 series: With zinc as the main alloy element, it has extremely high strength after heat treatment. It is one of the high-strength aluminum alloys, but has poor corrosion resistance and requires special surface treatment. Eg7075
Application
The aluminum alloy family is huge, and different brands have different “personalities”. The 1000 series is mainly made of pure aluminum, with first-class electrical and thermal conductivity, and is often used in wires, cables and food packaging. The 2000 series uses copper as the main alloy element and has high strength. It is the darling of the aerospace field. Many key structural parts such as aircraft are made of 2024 aluminum alloy. The 3000 series contains manganese, has good formability and corrosion resistance, and is commonly used in construction and automotive interiors. The 5000 series contains magnesium and is resistant to seawater corrosion and plays an important role in shipbuilding. The 6000 series contains magnesium and silicon and has good overall performance. Most aluminum alloy doors and windows are 6063 aluminum alloy. The 7000 series contains zinc and is extremely strong. It is often used in parts that require extremely high strength, such as aircraft landing gear.
