Product Description:

Aluminium is a relatively soft, durable, lightweight, ductileand malleablemetalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Q:Why is there any static electricity on the surface of aluminum profile? Ten
The problem is on the oxide film or coating of the aluminum profile!Aluminum is very lively! Very easily in the air and oxygen, carbon dioxide, water oxidation and galvanic reaction generated! White aluminium hydroxide and aluminum carbonate! So that its surface will lose luster! In order to solve this problem! Is usually on the surface of aluminum shaped material is covered with a layer of very thin oxide film or electrostatic synthesis there are also cover coating thin polyester film!! this makes the surface and is completely isolated from the air!
Q:Aluminum bending or curling
Ordinary people are squeezed out, take it with the mold, pull the bending and then aging, already aging good profiles can also pull the bend, that is, no aging before pulling good-looking, to pull the bend, the most important thing is to mold

Q:How are the tonnage grades of aluminum extrusion machines classified?
Aluminum Alloy stamping metal iron because material is relatively soft, expensive, easy to break and some Aluminum Alloy products also need subsequent processing, such as drawing, anode processing, especially in stamping production to produce top injuries, scratches, in the mold manufacturing should pay special attention to the following:1, for the project does not affect the number of cases, punching as far as possible behind the project, punching, and even for punching a large number of products, may consider more than one project, but also the punching line in the back.2, aluminum material is soft, and the mold is easy to block material, so in the design of mold gap should be put bilateral material thickness of 10% gap, the knife edge straight depth to 2MM is more appropriate, the taper to 0.8-1 degrees is appropriate.3, bending forming, because aluminum material in bending when easy to produce aluminum chip, will cause spot injury, indentation, aluminum raw material needs to stick PE film, in the roller and electroplating case, forming block with polishing hard chromium is better.4, the need for anode processing after stamping, such as pressing and flattening process of 180 degrees, the product can not be completely pressed, completely pressed will spit acid phenomenon for 0.2-0.3MM seam, acid to timely outflow, so we must do this step on the limiting block and calibration mode is higher than the norm out on.5, because the aluminum material is crisp, easy to crack, especially in the case of anti flanging, so try not to do the line, even if you want to do, but also to make the line width a little bit, a little lighter.6, all aluminum blade are required to use wire cut, to prevent the burrs and blanking is not smooth, easy to produce high temperature aluminum, so the punch hardness requirements of more than 60 degrees, at least with SKD11 material, has no D2 arithmetic matter punch.
Q:How much is aluminum freight per kilometer per ton?
The most accurate and effective way of Logistics: find a phone call to ask ah, less than 1 tons and tons of vehicle and hair are not the same, where to go is not the same, some small place to transfer is much more expensive, General Logistics 1 tons in about 500
Q:Aging hardness process of 6063 aluminum profile
Two 、 soft burning treatment:2.1 purpose:Materials for stretching and stretching include rolling materials, extrusion materials and forging materials:Casting - Hot Processing - cold processing - finished materialIn the process of hot or cold processing processing, material processing hardening, the strength increases or lead to work hardening, the strength increases or lead to reduced processing. In order to eliminate the work hardening, for cold working before or after the application of heat treatment is soft burning treatment. Its purpose is to make use of the material is needed.2.2 classification:Due to the different conditions of soft burning:2.2.1 part of soft burning: only part of the work hardening is eliminated, the treatment temperature is below the recrystallization temperature, the actual temperature depends on the strength, and the higher the strength, the lower the treatment temperature2.2.2 completely soft burning: treatment temperature in the recrystallization temperature or slightly higher, so that the material recrystallization, and completely eliminate the work hardening, also make the strength to the lowest stateThere is time and soft burning:2.2.3 soft burning before cold or cold start process, soft burning treatment added, usually completely soft burning, its purpose in the recovery process, and make the next function more smoothly, and the control of the organization, in order to fit for the final product requirements.2.2.4 ultimate soft burning: the main purpose is to adjust the final strength level of the finished product, that is, to adjust the chain3 processing common sense
Q:Will the aluminum profile be deformed at about 100 degrees?
Of course, you only choose the quality of aluminum, as far as possible to choose the hardness of high bar, 5052, 5056, 6082, 7075 and so on are high strengthAluminium alloy。Our common 6063-T5 material, the door and window material is the material.
Q:The number of aluminum profiles can be meters or KG. How exactly is it? How do you understand that?
You see the amount of it, if it is aluminum ingot is certainly in tons to calculate, the profile is, if it is a fixed size, usually 6 meters long.
Q:In aluminum processing, countersunk holes and via holes what difference?
Countersunk hole with flat drill or gongs knife on the board but not drilling drill (namely half hole) the transition part of the hole wall / hole wall at the maximum aperture and the minimum hole is connected with PCB parallel to the surface, size of hole part is flat, not inclined.
Q:Industrial aluminum profiles are generally used in what industry?
Kunshan Austrian crown aluminum to tell you: mainly used in the manufacture of industrial production, such as automation equipment, covering the skeleton and the custom mold machinery and equipment according to their own requirements, such as assembly line conveyor belt, hoisting machine, glue machine, testing equipment, shelves and so on, electronic machinery industry and clean room with.
