6000 Series Automotive Aluminum: 6101 and 6016

Aluminum alloy is one of the best lightweight materials at this stage. The density of aluminum is about 1/3 of steel. The specific strength of aluminum alloy is about 50% higher than that of high-strength steel.

In terms of cost performance, although the price of aluminum alloy is about 150% higher than that of steel, it is far lower than that of carbon fiber composite materials. Although the price of magnesium alloy is similar to that of aluminum alloy, it is not as corrosion-resistant as aluminum alloy, making it difficult to be widely used in the automotive industry. Therefore, aluminum alloy is the core of automotive lightweight materials.

6000 series automotive aluminum sheets are mainly 6016-T4/T4P, 6111-T4/T4P, 6014-T4/T4P, and 6451-T4/T4P alloys. 6111 alloy is an American alloy, registered with the American Aluminum Association in 1982; 6014 alloy was developed in Switzerland and registered with the American Aluminum Association in 1983; 6016 aluminum sheet is also a Swiss alloy that was formed in 1984 and registered with the American Aluminum Association.

AA6016 aluminum sheets are used in car door outer panels. They can meet the dent resistance design requirements by increasing the sheet thickness and optimizing certain structures. On the premise of meeting the stiffness, strength design requirements and relevant collision regulations, AA6016 aluminum alloy plates can be widely used in car door outer panels to replace traditional steel plates, reducing the weight by more than 40% and achieving lightweight purposes.

The yield strength of 6016 alloy is before baking is 119MPa, and it can reach 218MPa after baking. The 6016 aluminum sheet properties of Haomei Aluminum are basically consistent when benchmarked with materials from well-known international brands. Another very important performance of this material is stability. After being placed for 180 days, its strength is basically very stable.

6101 aluminum sheet is often used to process high-strength bus conductors. After introducing pre-straining and pre-aging on the basis of artificial aging, the mechanical properties and electrical conductivity of 6101 aluminum alloy have been improved. The interaction between strain strengthening and precipitation strengthening caused by the introduction of pre-strain and pre-aging is the fundamental reason why the mechanical properties and electrical conductivity of 6101 aluminum alloy are improved.
