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 ...

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...

What are the advantages of aluminum profile frames compared to other metal frames
2020-01-07
Nowadays, in many industrial automation production industries, aluminum profiles are often used to build frames.This is mainly because aluminum profiles have anti-corrosion, non-ferromagnetic, machinability, formability. , High electrical conductivity, low thermal conductivity and so on. Compared with other metal frames, what are the advantages of aluminum profile frames? Why are frameworks made o...

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...

Eight main points of aluminum extrusion die design
2020-05-12
To manufacture a set of high-quality aluminum extrusion dies, not only must there be good processing equipment and skilled extrusion die manufacturing workers, another very important factor is to have a good extrusion die design. For more complex extrusion dies, the quality of the die design accounts for 85% of the quality of the die. An excellent die extrusion tool design is: on the premise of me...
