Order an aluminum profile: what you need to know

Вебинары AEC: от профессионалов к профессионалам

Unfortunately, just recently we - the aluminum-guide.com team - discovered the webinars of the American industry organization of aluminum extruders - The Aluminum Extruders Council. The purpose of these webinars is to reveal to engineers, constructors, designers, as well as managers and marketers huge possibilities of extruded aluminum profiles in construction and design, in the automotive industry, in household and sports goods.

Experienced professionals in their field - technologists and material scientists, конструкторы и менеджеры производства делятся своими секретами:

  • How to construct a profile, чтобы его производство было как можно более дешевым и оптимальным?
  • What elements need to be laid in an aluminum profile, чтобы он мог выполнять свои функции с максимальной оптимальностью?
  • What benefits can be obtained, if you replace parts made of traditional materials, for example, steel, на детали из алюминиевых сплавов?

Aluminum - material and philosophy

Aluminum as a material and aluminum extrusion as a process offer unique properties and technological capabilities to product designers for various markets. A deep understanding of the unique capabilities of aluminum alloys and the extrusion process - the philosophy of aluminum - opens up boundless spaces for the designer for creativity and creation of new solutions for all areas of human activity.

  • Как использовать уникальные свойства алюминия для разработки новых товаров?
  • Что могут дать конструктору различные алюминиевые сплавы и их варианты?
  • Какая может выгода от применения более сложных конструкций профилей?
  • Какие эффективные технологии применяют при работе с алюминием?

All about the possibilities of structural aluminum

These and other issues were discussed at the last webinar from 4 November 2016 года, which was organized by one of the leaders in the aluminum industry - by SAPA corporation.

Тема вебинара: Leveraging Aluminum’s Attributes for Effective Extruded Solutions

This one-hour webinar provides a visual and detailed overview of the many nuances of aluminum profile manufacturing., a, the main thing, emphasizes all the advantages of aluminum as a material and extrusion as a technology to achieve the most effective results when developing new aluminum profiles.

Focus of the report – три основных рычага для поиска новых решений:

  • selection of aluminum alloy,
  • product geometry and
  • production technology.

The choices in these three areas have been illustrated with numerous case studies across different areas and market niches..

После этого вебинара начинаешь лучше понимать:

  • возможные решения для применения прессованных профилей в самых различных товарах;
  • возможности и ограничения различных алюминиевых сплавов;
  • techniques for designing effective aluminum profiles with minimal costs for their production.

Below we present some excerpts from this webinar., which were especially helpful to us. You may like other.

In addition to acquiring technical knowledge, there is also another benefit – natural spoken English on familiar technical topics. Английский язык для настоящего профессионала никогда не бывает лишним!

Below we present the first part of the review of this webinar..

Мы все – экструдеры!

We are all ourselves, with children or grandchildren - at least once, but were extruders. Экструдерами пластилина (рисунок 1). Эта простая пластмассовая машинка моделирует и разъясняет основные принципы прессования: профили сплошные и полые, solid and combined matrices, workpiece quality, pressing speed and the like

Aluminum extrusion

При экструзии алюминия сущность процесса остается той же – протолкнуть мягкий материал через заданные отверстия (рисунок 2).

However, in fact, aluminum extrusion is a difficult and multifactorial process. To obtain aluminum profiles of a given shape with a good surface and high strength, complex equipment is used., which includes not only a powerful and high-precision extrusion press, but also several ovens, drank, рольгангов и транспортеров (рисунок 3).

В печи старения (рисунок 4) профили из термически упрочняемых алюминиевых сплавов, for example, 6060 and 6063, reach the specified state of the material - specified mechanical and other properties. These states are indicated by letters and numbers., for example, T5, T6, T66.

Three important technological steps

При достижении заданных механических свойств алюминиевого профиля очень важное влияние оказывают следующие три технологических операции (см. Figure 3):

  • №1 – The temperature of the metal when passing through the matrix must have a temperature, which is sufficient for the complete dissolution of all alloying elements in aluminum
  • №2 – After the profile leaves the matrix, it should receive sufficiently intensive cooling., to keep Mg2Si particles in a solid solution of aluminum and, in the same time, избежать чрезмерного коробления профиля (рисунок 5)
  • №3 – Профиль пройти полное искусственное старения для роста и выделения упрочняющих выделений на основе Mg2Si (см. Figure 4).

The advantages of aluminum in structures and products

Army mobile bridge

  • Modular bridge, который перевозят на грузовике или вертолете (рисунок 6)
  • 10-12 soldiers assemble and install in an hour and a half
  • 18 meters of the bridge can withstand light vehicles and 130 soldier
  • Алюминиевый сплав 6061-Т6 и 6005-Т6; без сварки, only studs and bolts

Aluminum heat exchanger radiators

Прессованные алюминиевые радиаторы (рисунок 7) – это идеальные теплообменники для автомобилей, освещения и электронного оборудования:

  • cheaper manufacturing
  • high specific heat transfer
  • thin walls
  • built-in cavities
  • minimum porosity

All this gives them clear advantages over competitors - cast heat exchangers.
