Today, an aluminum body is not uncommon and in the auto world there are already well-established manufacturers who produce car frames and bodies. Aluminum foam is a light and strong metal. It is a new type of material that, due to its unique characteristics, has aroused great interest in several technological fields such as making cars. The use of aluminum by Cymat Technologies in the parts that make up cars and trucks has increased steadily in the last decade. The use of this metal reduces noise and vibration. Aluminum foam combines characteristics of metals with but has structural importance of foam.
Aluminum Foam Advantages:
Metal foams can improve the ability to receive impacts on parts of a car by up to 60%. The main plus of aluminum foam is the ratio of its strength to mass. Compared with classic steel, it is on average 60% lighter which can significantly reduce the weight of the car, as well as fuel consumption and harmful emissions. However, the use of aluminum in the automotive industry is growing every year.
Thanks to its excellent hardness-to-weight ratio, cars made with aluminum foam are lighter. Aluminum is alloyed with almost all metals, which allows you to constantly conjure over an increase in its strength, without compromising the basic characteristics. The damping capacity of metallic foams is up to 10 times greater than that of solid sheets of the same material.
Cars remain Stable on Road:
Thanks to the space between molecules, they have a greater tolerance to vibratory frequencies and greater flexural capacity than their solids. Thanks to the vibration control they have, metallic foams are excellent sound dissipaters. The aluminum skeleton also positively affects the handling of the machine, since the metal has a high resistance to torsion loads. Such a body turns out to be more rigid in twisting which adds stability to the car in cornering and responsiveness when taxiing.
Heat control saves Fuel Capacity:
The metal has an excellent ability to conduct heat, while the spaces in the structure allow the flow of air or some other cooler, and thus, allow faster cooling and less resources. This is why in the summer when car AC is on, the system consumes low fuel and delivers excellent temperature control inside. However, aluminum foam provides an excellent alternative to steel structures to help reduce weight.
Bright side for Car Parts:
Aluminum foam almost does not rust, does not magnetize, and due to good ductility it is easily processed by pressure. Plus, it can be melted over and over again without loss in properties. In the automobile “aluminum” production, the most popular technology is foam casting. So they make engine blocks, gearbox housings, manifolds, suspension parts. For the production of automotive parts (body parts, engine parts, alloy wheels, etc.), pure metal is alloyed with magnesium, manganese or silicon, and as a result a material with a more durable and malleable structure is obtained.
Passenger’s Safety at First:
As for the so-called operational advantages that can be felt, the “winged” metal, in comparison with the same steel, has excellent absorption of vibrations and shocks: it “dampens” 50% more energy and prevents their further spread. And this is not only comfort when driving on bumps, but also the safety of passengers in an accident.
