6111-t4 Aluminum Mechanical Properties

 The lightweight of automobiles has become the trend of the development of the world automobile industry. There are two ways to reduce the weight of automobiles: one is to optimize the car frame structure; the other is to use lightweight materials. Aluminum alloys have the advantages of light weight, wear resistance, corrosion resistance, high specific strength, good impact resistance, and easy surface coloring, etc. More than 80% of aluminum can be recycled and reused, making aluminum alloy an ideal lightweight material for automobiles.

6000 series aluminum alloys like 6111 aluminum have the characteristics of heat treatment strengthening, which just matches the existing automobile body production system. The prepared and processed aluminum alloy plates can be solid solution and pre-aging in the material factory to make them have good rormability, and then go to the automobile factory for stamping and forming to manufacture body components. Therefore, 6XXX aluminum alloys are considered to be the most promising aluminum alloy materials for automobile bodies.

The main parts of aluminum alloy sheet used in cars are the body in white (four doors, two covers and fenders). The types of alloys involved include 6016, 6022, 6111, 6181, 5754, 5182 and 5052. Among them, the inner body panels are basically made of 5182 alloy and 6181A alloy, while the outer body panels are mainly made of 6016, 6111 and 6022 alloys.

In the early 1980s, North America and Europe respectively developed high-Cu 6111 aluminum alloy and low-Cu 6016 aluminum alloy. On the basis of 6010 aluminum alloy, the paint hardening and formability of 6111 aluminum alloy were significantly improved.

6111 aluminum alloy has higher strength after baking paint treatment. European car manufacturers mostly use low Cu 6016 aluminum alloy with better formability, and the United States uses more 6111 aluminum alloy and 6022 aluminum alloy with higher strength properties.

The strength of the 6111-T4 aluminum plate is only increased by 20MPa after baking at 185℃/20min. In the process, pre-aging treatment is generally used to suppress or alleviate natural aging, and at the same time increase the yield strength increment after baking.

The high toughness, corrosion resistance and weldability of aluminum alloys provide a good choice for building lightweight ships. It is more economical to use aluminum to build ships due to its lower processing costs. Aluminum alloy can be used as a sheet, and can also be processed by extrusion and casting.

From the point of view of ship designers, ships made of aluminum alloys can achieve higher speeds and longer service life. These advantages of aluminum alloys have made them rapidly developed in the application of ships.

In the 1830s, 6061-T6 aluminum alloy was used, and the hull was constructed by riveting. In the 1940s, a weldable and corrosion-resistant aluminum-magnesium alloy was developed. In the 1950s, TIG welding technology was used. In the 1960s, the US Navy developed 5086-H32 and 5456-H321 alloy sheets, 5086-H111 aluminum alloy and 5456-H111 aluminum alloy extruded profile.

At present, the aluminum alloys used in the hull structure are mainly 5083, 5086 and 5456, which have good mechanical properties, corrosion resistance and weldability. The Norwegian Shipbuilding Association stipulates the use of 5454 aluminum alloy, and the tensile strength of its sheet is the same as that of 5086 aluminum alloy. In the United States, 5456 aluminum alloys are mainly used.

5456 aluminum H116 and H117 are finally rated as the best material for the main shell structure due to its advantages in mechanical properties, corrosion resistance and cost. 5456-H112 alloy is selected as the extrusion, because its specific strength is 19% larger than that of 5086-H112 aluminum sheet.

5083 6061 Aluminum Sheet for Bus Body

 For the buses, the trend of new energy has been unstoppable. In major and medium cities, pure electric and other new energy buses have been put into operation. However, at present, there has always been a serious problem for new energy buses, especially pure electric buses.

Due to the addition of a large number of battery packs to the vehicles, to a certain extent, compared with fuel buses, at least 1- 2 tons weight is added. Originally, there is a problem with the battery life of pure electric buses, and such an increase in weight greatly reduces the cruising range of the vehicle.

In terms of realizing the lightweight of the body and the weight reduction of the whole vehicle, the all-aluminum body structure has become the most effective way. With its excellent characteristics, it has been set as the standard configuration of the body frame and skin of new energy buses, especially pure electric buses, by many bus OEMs and bus companies.

The frame of the whole vehicle is welded by 6 series aluminum alloy, and the skin is completed by 5 series aluminum plate. The aluminum bus body brings long cruising range, and its weight reduction ratio is more than 30% compared with the general steel body. The car adopts a low entrance structure, and the interior space is spacious, with a maximum passenger capacity of about 80 people.

The main aluminum used in the bus is 6061 t6 aluminum plate. The main connecting parts are fully riveted. The weight of our 12-meter bus has been reduced by 500kg to one ton. The 12-meter city bus that has been supplied in batches weighs about 920 kilograms.

Vans and semi-trailers both adopt lightweight frame. The material is generally high-strength aluminum alloy (or high-strength steel plate), and equipped with air suspension , aluminum alloy rims, 425/65R22.5 tires,etc.

For example, the tank body of oil tanker produced in China is made of marine grade aluminium 5083 6mm sheet. The front and rear heads are made of 5083 7mm thick aluminum alloy.

On the premise of ensuring the quality, the weight of the body is greatly reduced, and the weight of the whole vehicle is only 7600kg (the weight of the ordinary steel structure 3-axle liquid tanker is about 11 000kg).

Impresión offset: PS or CTP Placa

 En la producción de libros, la impresión offset es un eslabón de producción importante y los costos de impresión representan una gran proporción de los costos de producción de libros. En la actualidad, la impresión offset de planchas CTP y PS son los dos métodos principales de impresión de libros con diferentes costos y diferentes beneficios económicos. ¿Cuál es más rentable?

Se puede ver en el proceso de impresión CTP que en el método de impresión CTP, dado que la información de diseño de la publicación se envía directamente a la placa de impresión, en comparación con la impresión PS, su costo de impresión solo tiene el costo de la salida de muestras digitales, placa CTP costo de fabricación y el costo de impresión.

Bajo la impresión offset de placa PS, el costo del proceso de impresión incluye: película de salida, prueba de placa PS, costo de placa PS, costo de impresión, etc.

Cuál elegir

¿Qué método es la elección correcta? Al elegir un método de impresión, los editores deben considerar factores como la calidad y el ciclo, pero es más importante reducir los costos. En los dos modos anteriores, la tarifa de salida de la película, la tarifa de prueba y la tarifa de impresión son las razones principales de la diferencia de costos.

A través de la comparación de datos, se encuentra que bajo el método de impresión CTP, excepto que el costo de un solo libro en una edición y una impresión es ligeramente más alto (porque hay una tarifa de muestra digital), los costos posteriores son los mismos.

Sin embargo, la impresión de placas PS es diferente. Durante el ciclo de vida del libro, la tarifa de salida de la película y la tarifa de prueba en el modo de impresión de la versión PS son costos fijos (es decir, el costo total permanece sin cambios). En el cálculo del costo, debe asignarse a un solo libro. De esta forma, con el aumento del número de copias y el número acumulado de copias, la asignación de costos para un solo libro disminuye gradualmente.

Al mismo tiempo, los datos de comparación también muestran que el costo de CTP es mucho más bajo que el de la impresión PS cuando se imprime una versión una vez, pero es básicamente el mismo cuando se reimprime por segunda vez, y el costo de PS versión es inferior a la de la impresión CTP cuando se imprime por tercera vez.
