China professional aluminum sheet supplier introduces you what is 6063 aluminum


6063 aluminum is an Al-Mg-Si series high-plasticity alloy, which has superior processability, excellent weldability, extrudability and electroplating, good corrosion resistance, toughness, easy polishing, easy polishing, and color film Anodizing effect is excellent, it is a typical extruded alloy.

What is 6063 aluminum-about characteristics

1. Strengthened by heat treatment, high impact toughness, not sensitive to notches.

2. It has good thermoplasticity and can be extruded at high speed into complex, thin-walled, hollow profiles, or forged into complex forgings. The quenching temperature range is wide and the quenching sensitivity is low. After extrusion and forging demoulding, as long as the temperature is higher than the quenching temperature, it can be quenched by spraying water or passing through water. Thin-walled parts (δ <3mm) can also be air-quenched.

3. Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency. Among heat-treated and strengthenable aluminum alloys, Al-Mg-Si-based alloys (including 6063 aluminum) are the only alloys where no stress corrosion cracking is found.

4. After processing, the surface is very smooth and easy to anodize and color. Its disadvantage is that if it is left at room temperature for a period of time after quenching, it will adversely affect the strength in terms of aging (the parking effect).

What is 6063 aluminum-about alloy elements

The main alloying elements of GB 6063 aluminum are magnesium and silicon, and form a Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance; there is still a small amount in conductive materials Copper to counteract the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine the grains and control the recrystallization structure; in order to improve machinability, lead and bismuth can be added. In Mg2Si, the Mg / Si ratio is 1.73. In the heat-treated state, Mg2Si is solid-melted in aluminum, so that the alloy has an artificial aging hardening function.

What is 6063 aluminum-the difference from 6061 aluminum

Aluminum sheet supplier introduces, the difference between 6061 alloy aluminum and 6063 alloy aluminum is different in hardness. This is due to the different content of alloy elements. The hardness of 6061 aluminum plate is higher than that of 6063 aluminum plate. The price of 6061 aluminum plate is more expensive than 6063.
