5182 and 6101 Aluminum Alloys for Automobile

 With the rise of new energy vehicles and the development of the energy Internet, busbars will replace standard cables and are widely used in the manufacturing of new energy vehicles, as well as in emerging industries such as robot manufacturing, smart grids, and photovoltaic equipment. In particular, soft busbars have become an important power transmission technology in the new energy field.

Soft busbar has the advantages of high transmission efficiency, safety and stability, and small footprint, so it is widely used in charging piles, power distribution cabinets, power replacement equipment and other fields.

6101 aluminum alloy has medium strength and high electrical conductivity and can be used for long-distance power transmission lines. Compared with traditional steel-core aluminum alloy stranded wire (ACSR), all-aluminum alloy stranded wire (AAAC) twisted from a single Al-Mg-Si alloy wire can well avoid electrical corrosion and can improve power transmission efficiency.

At the same time, the maintenance cost of transmission lines is reduced. More importantly, the Al-Mg-Si series alloys are heat-treatable strengthened alloys, and their strength and conductivity can be adjusted by solid solution + aging heat treatment.

ABS car panels have high requirements on the mechanical properties of aluminum plates, and have strict standards for the flanging performance and surface quality of the aluminum plates. The cold rolling rate of BS is generally required to reach 85%. Conventional aluminum alloys used for ABS include: 2002, 2117, 2036, 2037, 2038, 3004, 5052, 5182, 6009, 6010, 6015, 6016, 6111, etc. Except for 3004 and 5182 aluminum alloys which are used in the O state and 5052 alloy which are used in the H32 and H34 states, other alloys are used in the T4 state.

In terms of deep stamping performance and tensile strength, 5052 aluminum alloy is far less good than 5182 alloy. Therefore, the first choice aluminum alloy for inner panels of complex shapes is 5182-O aluminum sheet. Find 5182 o aluminum properties from Haomei Aluminum.

The car doors, hood panel and trunk lid all can choose 5182 aluminum alloy. Since the 5182 aluminum plate has excellent deformability, it can absorb the impact very well when it is hit by external forces, protecting the driver and passengers to a great extent.

The mainstream automobile aluminum sheet production technology: semi-continuous casting (direct chill casting, DC) to produce large- sized flat ingots- sawing the head and tail- cutting the surface- heating- high-temperature rolling in a large wide-width hot rolling unit- aluminum coil- cold rolling process to finished product thickness- heat treatment with air cushion continuous heat treatment furnace. If it is necessary to control the material microstructure and grain size, an intermediate annealing process can be added to the cold rolling pass.

6016 Aluminum Used in Automotive Industry ​

 Since aluminum alloy has the characteristics of light weight, wear resistance, corrosion resistance, high specific strength, good impact resistance, easy surface coloring, etc., and more than 80% of aluminum can be recycled and reused, it has been an ideal lightweight material for automobiles.

Since the 1970s, developed countries in the automobile industry such as Europe, America and Japan have invested a lot of manpower and material resources in the development to develop 6xxx aluminium used in automotive industry and successively developed and registered international aluminum alloys such as 6009, 6010, 6016, 6111, and 6022.

6000 aluminum alloys are heat-treatable-strengthened aluminum alloys with high strength, good plasticity and excellent corrosion resistance. 6-series alloys are the main force of body panels. The yield strength and tensile strength of the 6xxx T4 aluminum plate is similar to the steel plate and its hardening coefficient even exceeds that of the steel plate.

6009, 6010 and 6016 aluminum alloys are currently used for exterior and interior panels of automobile bodies due to their good plasticity and the ability to achieve high strength through artificial aging during the paint-baking process after forming. The body panels of the Audi A8 are made of this series of aluminum alloys.

6016 aluminum alloy is is widely used in ABS, but the heat treatment process is complicated, and pre-aging treatment T4P must be performed between solution treatment and paint treatment to obtain good performance. Because it should have good formability before stamping, and can rapidly increase the strength during the paint baking process after stamping, so as to have high dent resistance.

Al6016 is also used to make anti-collision beam. Compared with the steel plate front anti-collision beam assembly, the use of 6016 aluminum alloys to manufacture the front anti-collision beam not only greatly reduces the weight, but also improves the anti-collision effect.

The Features of 6xxx Automotive Aluminum Sheets

 6xxx automotive aluminum is an aluminum alloy with magnesium and silicon as the main alloying elements and Mg2Si phase as the strengthening phase, which is a heat-treated aluminum alloy. It has medium strength, high corrosion resistance, no stress corrosion cracking tendency, good welding performance, unchanged corrosion performance of the welding zone, good formability and process performance.

When the alloy contains copper, the strength of the alloy can be close to that of the 2 series aluminum alloy, and the process performance is better than that of the 2 series aluminum alloy, but the corrosion resistance becomes worse. The most widely used 6xxx automotive aluminum sheets are 6061 and 6063.

The main grades of 6xxx aluminum alloy are 6005, 6060, 6061, 6063, 6082, 6201, 6262, 6463, 6A02 and 6056 aluminum alloy. There is a brief introduction of 6056 aluminum:

6005: it is used for structural parts that require a strength greater than 6063 alloy, such as ladders, TV antennas, etc.

6061: It is used for a variety of industrial structures requiring certain strength, weldability and high corrosion resistance, such as trucks, ships, mechanical parts, car body panel,etc.

6063: It is often used as industrial profiles, construction profiles, irrigation pipes and extrusion materials for vehicles, benches, furniture, fences, etc.

6101: It is used for high-strength bars for buses, electrical conductors and radiator materials, etc.

6151: It is used for die forging crankshaft parts, machine parts and production of rolled rings. It is used for applications that require good forgeability, high strength, and good corrosion resistance.

6201: It is used to make high-strength conductive rods and wires.

6262: It is used to make high-stress parts which require higher corrosion resistance than 2011 and 2017 alloy.

6A02: It is used to make aircraft engine parts, complex forgings and die forgings.
