New perspectives for aluminium strip production

Exact knowledge of the surface roughness and thickness of the oil layer provides pressing plants in the automotive industry with enormous potential in terms of reducing their waste and enhancing process reliability before continuing to process aluminium strip or plate material. The oil layer measurement, however, has specific requirements. The trend is towards higher strength material with thinner oil layers, which, overall, means enhanced requirements for the pressing process in terms of accuracy. Due to the close relationship between the oil layer and material roughness, as well as the significant influence they have on the forming process, e.g. for the automobile manufacturer, accurate monitoring and control of both factors during production of the strip will provide the aluminium manufacturer with an important competitive advantage

Structure of Aluminum Foil Flexible Pipes

Aluminum foil flexible pipes can deliver all kinds of media of temperatures between -50℃ and 150℃. They are applied in heat or cold maintaining projects for centralized heating, central cooling and hot oil delivery in industries like petroleum, chemical, coal, refrigeration and heating supply. Although you may have caught sight of the pipes a lot in daily life, you might not pay enough attention to their structures.

Why copper and aluminum are used in HVAC coils

HVAC coils are often made with copper and aluminum, two metals that efficiently transfer heat. That’s because cost and effective heat transfer are often the key deciding factors in choosing materials for HVAC coils. There are pros and cons to both copper and aluminum, which I describe below.

Why are aluminum coils so corrosion resistant?

Aluminum is actually a very active metal, in the sense that it oxidizes very quickly. This feature, while a weakness for most metals, is actually the key to its ability to resist corrosion. When oxygen is present (in the air, soil, or water), aluminum instantly reacts to form aluminum oxide. This aluminum oxide layer is chemically bound to the surface, and it seals the core aluminum from any further reaction. This is quite different from oxidation (corrosion) in steel or other metals, where rust puffs up and flakes off, constantly exposing new metal to corrosion. Aluminum’s oxide film is tenacious, hard, and instantly self-renewing.
