Typical defects and causes of aluminum alloy profiles
2019-05-09
1. Aluminum alloy profiles bending and twisting, wave Due to the unreasonable design of the die hole, the extrusion speed is too fast, the die hole lubrication is not proper, the guide path is not suitable or the guide is not installed. 2. Bubbles and peeling due to the inner diameter of the extrusion barrel is excessively worn, the gap between the pressing pad and the barrel is too large; the ext...

Causes and solutions for the formation of surface particles of extruded aluminum profiles
2019-05-31
Abstract: In the extrusion production of aluminum profiles, some small particles on the surface of the profile are adsorbed on the surface of the profile, and the touch is touched, which affects the surface appearance of oxidation, electrophoretic painting and sprayed profiles, and reduces production efficiency and Yield.Therefore, the formation mechanism is analyzed to take measures to reduce or ...

An Introduction to Aluminum Extrusion and Profiles
2019-08-30
The aluminum extrusion (also known by ‘aluminum frames’) forming process is a bulk plastic deformation process. First, a billet of aluminum is preheated to a specified temperature that is still comfortably below the material melting point in order to facilitate the plastic flow of the material. The heated billet is then forced through a tooling die that is designed to shape and form the bill...

Vietnam adopts anti-dumping measures against Chinese aluminum profiles
2019-10-17
The Ministry of Industry and Trade of Vietnam recently issued a decision to take anti-dumping measures against some aluminum extruded profiles from China. According to the decision, Vietnam imposed a 2.49% to 35.58% anti-dumping duty on Chinese aluminum extruded bars and profiles. The number of Chinese aluminum profile manufacturers surveyed was 16. Previously, the Ministry of Industry and Trade o...

The role of various elements in aluminum alloy
2019-12-09
Cu The maximum solubility of copper in aluminum is 5.65% when the aluminum-rich portion of aluminum-copper alloy is 548, and the solubility of copper is 0.45% when the temperature drops to 302. Copper is an important alloying element and has a certain solid solution strengthening effect. In addition, Cu Al2 precipitated with aging has a significant aging strengthening effect. The copper content in...

Advantages of new aluminum wood doors and windows
2019-12-19
There are two types of doors and windows, one is aluminum-clad wood doors and windows, and the other is wood-clad aluminum doors and windows. 1. The concept of aluminum-wood composite was originally introduced by Germany, and domestic manufacturers have processed this concept and imitated aluminum-wood composite doors and windows in form, so today there is aluminum-clad wood. 2. From the appearanc...

60 Series Alloy Temper and Application in Detials
2020-01-19
60 series (Al-Mg-Si) alloy is the most important extruded alloy. At present, more than 70% of aluminum extrusion processed materials in the world are produced using 60 series alloy. % Si, 0.35% to 1.4% Mg. Within this limit, countries have developed hundreds of alloys with different compositions. The American AA standard alloy table lists 46 different series of 60 series alloys, and the Internatio...
