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...

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...
