aluminum advances: aluminum passes iron among automotive materials in use worldwide; what lies ahead?

by:AAG     2020-11-03
In 2006, just five years after overtaking plastics for use in cars and light trucks around the world, aluminum overtook Iron and took second place in automotive materials.
According to the duckerworld report released on 2006,-
Aluminum content of Light non
Commercial vehicles to be assembled in North America, Japan and the EU in 2006--
The average aluminum content of the global car reached nearly 280 pounds in the 2006 model year.
The report brought more good news about the rise in aluminum in the North American auto market, which averaged 319 pounds, up nearly 24% in the past five years.
In the historical context, the achievements made by aluminum in the first five years of the new millennium are only a continuation of the trend since the medium term1970s--
In the past 30 years, the aluminum usage of light vehicles in North America has increased every year.
Factors driving the increase in usage include continuous oil shocks, legislation encouraging automakers to improve fuel efficiency in their cars, and consumers\' desire for larger cars with more power, expanded functionality, and improved performance.
What are the factors driving material selection forward?
How can the aluminum industry help automakers cope with future challenges?
What are the new automotive aluminum technologies coming out soon?
These questions are discussed in this story. FOCUS ON R&D.
Six weeks after the Ducker report was released at the aluminum Society Spring meeting,
Gerald Cole, president of lightweight Strategy LLC, talked about opportunities for automotive aluminum.
Lightweight materials like aluminum, hersard, now in a number of factors, including rising gasoline prices, help the car makers in a unique position, Americans want to be independent from foreign oil, and worry about the contribution of car emissions to global warming.
Cole, a former senior technical expert at Ford Motor.
Ford said consumers are expected to continue
Sizepickup trucks and SUVs as well as cross vehicles and more fuel
Efficient Car (
Seven months before 2006, the United StatesS.
Passenger car sales growth 2.
2%, light though-
10 trucks are sold. 6 percent).
Ford and GM both make significant investments in hybrid and flex, he added
Fuel technology.
\"Is the aluminum industry involved in this technological change? \" Cole asked.
\"Developing low cost requires more and smarter R & D.
Lightweight aluminum automotive materials with cost and functionality help maintain the development of the US automotive industry. S.
At the forefront of the automotive industry, \"Cole said.
As an example, he cited the potential of continuous casting to help aluminum automotive plate products become more competitive on a cost-based basis in body applications.
\"In order to make continuous casting aluminum a viable process for stamping automotive sheets, a lot of research and development is required,\" says Colesaid . \".
The Ducker report agreed to use aluminum in \"new innovative applications ---
It is defined as all the components except the powertrain, the powertrain, the wheel and the heat exchanger ---
In light vehicles, North America is behind Europe and Japan is third.
In the field of aluminum closed board shipments, consumption in Europe will exceed the sum of North America and Japan in 2006, and the Ducker project will continue to do so at the end of the decade. Two-
In 2006, 30 of the world\'s 0. 57 billion-pound aluminum sheets (
Twice the shipment in 2002)
European automakers including BMW and Mercedes-
Produce more than one part of aluminum body structure every year-
Audi, Jaguar, Ferrari, Rolls-Royce and Lotus have almost reached their combined product. Aluminum body.
Similarly, according to Ducker\'s report, Europe is the largest aluminum user in the \"distant\"--
The aluminum consumption of these parts is more than double that of North America and Japan.
Taxiing or driving forward?
Despite Europe\'s leading position in innovative aluminum applications, 2006-
North American models still surpass European peers in the use of aluminum, with an average aluminum usage of almost 60 lbs per vehicle.
This is the result of North America\'s preference for larger, more aluminum
Engine strength and (larger)
Automatic transmission is in use, while diesel engines are more common in Europe.
Ducker further reported that although the light aluminum cylinder head conversion worldwideCar engine--
Traditional drivers of growth in aluminum usage--
Almost finished, the use of aluminum in the engine block still has considerable potential.
For the first time in 2006, most of North America\'s engines-52percent--were aluminum.
Ducker predicts that the continuous conversion from iron to aluminum will be the main driving force for the growth of aluminum usage in the United States and around the world.
If the use of steel in cars is decreasing, then steel has become a major obstacle to aluminum.
Nevertheless, the United StatesS.
The aluminum industry is working with government researchers to develop costs-
Effective aluminum solutions in innovative applications to improve fuel efficiency and help develop more eco-friendly light vehicles.

Daimler Chrysler and the technology department of heavy vehicles have completed a project that includes the development of three prototypes of light vehicle frames.
In 2006, a prototype of an aluminum-steel hybrid was tested on the chassis of a2003 Dodge Durango.
\"The test results exceeded everyone\'s expectations and succeeded until we launched a more challenging follow-up --
\"The Up program is called the next generation framework,\" said Mark Smith, head of the PNNL energy materials group.
The next-generation frame prototype gave up the steel part of the frame and completely focused on aluminum.
PNNL reports that the weight of the aluminum frame is saved by more than 40%.
Then tested the aluminum frame on the latest model of Dodge Durango. FUTURE NOW.
Initiatives such as the next generation framework are significant.
Like aluminum.

At the same time, the Toyota subsidiary, Bodi aluminum, is trying to improve the productold gasoline-Poweredinternal-

The company makes aluminum engine blocks and cylinder heads for Toyota\'s top
While selling Camry and other models, it has also created a range of new technologies and costs.
Cutting Measures for model year 2007.
In April 2006, according to the Bloomberg market Problem Report, Bodinehas cut down the power plant of production cost to 2007 Camry byalmost 50% in the past three years, the scale is smaller, less

Foot Casters used to make Camry engine blocks have been replaced by smaller, more efficient casting machines.
The new casters use up to 40% lesspressure to inject aluminum into the mold, eventually creating stronger blocks with fewer bubbles.
Reduced injection speed means Toyota can make V-

Aluminum outlook.
Continued attention to energy supply and the environment indicates that the light weighing strategy remains important for the foreseeable future.
But aluminum must be high
The share of steel, magnesium and plastics in this market.
Automotive aluminum research and development must continue to seek to develop innovative new solutions in all areas of automotive-
Engine, transmission, chassis, suspension, closure, body structure, etc. --
Because its gains in one area may be offset to some extent by losses in other areas.
Changes in consumer preferences may also present challenges and opportunities (
For smaller vehicles, for example)
Even a large-scale \"paradigm shift \"(a large-
For example, the expansion of diesel engines in North America, or the widespread use of fuel
Cell Technology).
The Ducker report predicts that the global use of aluminum in cars will continue to grow, an increase of about 3% to three.
For the rest of the decade, 5% pounds a year.
Since then, the growth of aluminum is likely to depend on the technology being developed today.
