The biggest characteristic of aluminium heatsink extrusions is above its bulk density of about 1/3 steel, rather than strength (the strength limit and proportion ratio) can be reached or exceeded the structural steel. Secondly, aluminum and aluminum alloy is easy to be processed into various shapes, can adapt to all kinds of connection technology, so it can provide the most economic and reasonable section form with favorable conditions for building structure. It can also be used for aluminium heatsink extrusions field production. The color of aluminum and aluminum alloy is beautiful with good corrosion resistance, and they have light and heat on the high reflectivity, good sound absorption performance, through chemical and electrochemical methods can obtain different colors. So the aluminum extrusion widely used in industrial and civil buildings roof, walls, doors and windows, framework, internal and external decorative plates, ceilings, ceiling, railings, indoor furniture, store container and construction with the template.
The detailed aluminum extrusion profile
Aluminum extrusion installation construction content includes: aluminum alloy doors, window approach, check the level line, draw a vertical line, and the line, window frames, counterpoint, cleaning hole. Oblique wedge fixed frame, correction, nailing fixed iron feet, check. Mortar or concrete sealing is in thin iron feet. Iron feet mortar will follow after drying, removal of wedge, powder outdoor entrance. Note playing foaming agent, outdoor play first degree silicone. Then window frame sealing mortar, rubbing, and collecting of aluminum extrusion profile. Door and window frame inside play second degree silicone, outdoor play. After installation, the connecting piece, a foaming agent for concealing acceptance. The doors and windows of the vertical diagonal of actual measurement, the installing quality meets the requirements. In the aluminum alloy doors and windows installation, generally follow the following procedures and acceptance.
Production methods of extruded aluminium heatsink
Extruded aluminium heatsink in accordance with its production in different ways. It can be divided into casting aluminum alloy and aluminum alloy two categories. The building is used commonly on the deformation of aluminum alloy, used for rolling plate, strip, foil, rod, tube or extruded into various complex shapes. Deformation of extruded aluminium heatsink by its performance and the different use can be divided into antirust aluminum alloy, hard aluminium, super hard aluminium and special aluminum. Building in the general use of industrial always choose pure aluminum (L1 ～ L1), rust-proof aluminum alloy (LF2, LF21) and aluminum (LD2) etc.
www.aluminiumsupplier.com.cn was established in 1984. As one of the earliest enterprises engaged in aluminium profile in Mainland China, the Company has become a famous and large-scaled enterprise specialized in production of aluminium profiles for both architecture and industry, with its yearly capacity of 150,000 tons.
