Standard aluminium extrusions are also called general profiles or standard profiles. Otalum produces a wide range of standard aluminium extrusion profiles with different dimensions in the following groups: Angle, Bar, Tubes, U-channel.
All profiles are produced according to the standard GB5237.1-2017 with the following alloys, 6005, 6060, 6061, 6063, 6082, etc.
When ordering, please specify alloy, temper, length, quantity, surface finish, end-use and any special instructions regarding tolerance, delivery, packing and certification. It couldn't be better if you can share with us your designed drawings.
Carries a large inventory of extrusion tooling used in the production of standard aluminium extrusion profiles/shapes.
Supply a wide range of products with a variety of alloys, sizes and finishes.
Have extrusion presses from 500T to 5500T, can cover most of the sizes of standard profiles in almost all the applications.
Supply to the United State, Euro, Australia, Southeast Asia, and Latin America, have the commonly used standard profiles in these areas.
Pass the Certificate of CE, DNV, ISO.
Aluminum extrusion is defined as a process by which aluminum is forced to flow through a shaped opening in a die. A powerful press pushes the aluminum through the die and it emerges the die opening. The outcome is a long profile with the same shape as the opening in the die.
The result is a corrosion-resistant, lightweight material available in medium to high-strength forms. An interesting point about aluminum is that strength actually increases at very low temperatures. This contrasts with steel, which becomes brittle.
In the indirect extrusion process, the metal begins to flow through the die at the maximum value of the pressure called "breakthrough pressure". Therefore extrusion pressure is almost constant with an increase in ram travel. It represents the stress required to deform the metal through the die.
Extruded shapes are also known as profiles or sections. A shape has irregular or unusual cross-sections. Extruded shapes offer a component metal part with radii, contours and angles already pre-formed in the extrusion. This permits reduced scrap eliminates or reduces machining and results in less labor.
