6063 aluminum sheet is Al-Mg-Si alloy， with excellent processing performance， excellent solderability， extrusion and plating， good corrosion resistance， toughness， easy polishing， anodizing Excellent effect， is a typical extruded alloy.
6063 Aluminum sheet is widely used in construction profiles, irrigation pipes, vehicles, benches, furniture, lifts for its good plasticity
6063 aluminum plate is an aluminum-magnesium-silicon alloy with excellent processing properties, excellent weldability, extrudability and electroplating properties, good corrosion resistance, toughness, easy polishing, and excellent anodizing effect. It is a typical extruded alloy.
Mill finish 6063 aluminum alloy is widely used in the construction of aluminum doors, windows and curtain walls. It is an ordinary aluminum alloy model. In order to ensure that doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decoration performance, the comprehensive performance requirements of aluminum alloy profiles are far higher than the industrial profile standards.
The chemical composition of 6063 aluminum alloy has become an important part of the production of high-quality aluminum alloy building profiles.
6063 aluminum alloy is a medium-strength heat-resistant alloy of the AL-Mg-Si series. Magnesium and silicon are the main alloying elements. The main task of optimizing chemical composition is to determine the percentage of Mg and Si (mass fraction, the same below).
As long as the purchase of raw materials and alloy composition are effectively controlled to ensure that the ratio of magnesium to silicon is within the range of 1.3 to 1.7, the silicon corrosion behavior of 6063 aluminum alloy profiles can be prevented and controlled, and various process parameters are strictly controlled to avoid segregation and desiliconization. Silicon magnesium forms a favorable Mg2Si strengthening phase.
If this phenomenon of silicon corrosion spots is found, special attention should be paid to the surface treatment. In the degreasing and degreasing process, try to use a weak alkaline bath. If conditions do not permit, it should be soaked in acid degreasing fluid for a period of time. As short as possible (qualified aluminum alloy profiles can be placed in acidic degreasing solution for 20-30 minutes without problems, problematic profiles can only be placed for 1-3 minutes), the pH value of the cleaning water should be high (pH>4, control Cl Content), the alkali corrosion process should be as long as possible, nitric acid light solution should be used when neutralizing light, and sulfuric acid anodizing should be energized and oxidized as soon as possible, so that the dark gray corrosion points caused by silicon are not obvious and meet the requirements of use.
6063 Aluminum Sheet surface is very smooth, and easy to anodize and coloring; Heat treatment to strengthen, high impact toughness, not sensitive to the gap.
