とは何ですか 6061 aluminum plate alloy?
6061 アルミニウム合金 is a heat-treatable and strengthened alloy with good formability, 溶接性, と機械加工性.
中強度もあり、焼鈍後も良好な強度を維持できます。.
The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and they form Mg2S 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;
2024 アルミニウム vs 6061 composition difference
両方 2024 アルミニウム合金と 6061 alloy are metals with high hardness and good corrosion resistance and pressure resistance. The reason is that the chemical elements contained in the two aluminum alloys are different.
アルミニウム 2024 belongs to the AI-Cu-Mg system, そしてアルミニウム 6061 belongs to the AI-Mg-Si system.
Comparison of chemical composition of aluminum alloy 2024 そして 6061 |
合金 | そして | 鉄 | 銅 | ん | マグネシウム | Cr | 亜鉛 | の | その他 | アル |
2024 アルミニウム | 0.5 | 0.5 | 3.8-4.9 | 0.3-0.9 | 1.2-1.8 | 0.10 | 0.25 | 0.15 | 0.15 | 残る |
6061 アルミニウム | 0.4-0.8 | 0.7 | 0.15-0.40 | 0.15 | 0.8-1.2 | 0.04-0.35 | 0.25 | 0.15 | 0.15 | 残る |
2024 アルミニウム vs 6061 price difference
Due to the copper content in its composition, 2024 aluminum alloy is more difficult to make plate ingots during production, with a higher failure rate, which results in an increase in its production cost compared to 6061 アルミニウム合金. 2024 アルミニウム合金, especially 2024-T351 model, has a higher hardness, which makes it difficult to roll with ordinary hot rolling mills. Due to production costs and technical limitations, the supply of 2024 aluminum alloy is relatively small, which naturally leads to its higher price.
The price of 2024 aluminum alloy plate is generally about RMB 20 per kilogram higher than that of 6061 aluminum alloy plate, while the price of cutting processing is more than RMB 40 per kilogram.
Which is better between 2024 aluminum plate and 6061 アルミ板?
両方 2024 aluminum sheet and 6061 aluminum sheet have their own characteristics, and their characteristics vary depending on the application scenario.
2024 aluminum sheet is an aviation-grade aluminum alloy that is widely used in demanding industrial fields due to its excellent strength and hardness.
6061 aluminum sheet is a common aluminum alloy with good comprehensive properties and is suitable for a variety of machining and industrial applications.
The price of 2024 aluminum sheet is usually higher than that of 6061 aluminum sheet due to differences in its production cost and material properties.
If your application does not require extreme strength and hardness, 6061 aluminum sheet can meet the requirements and is more economical.
If your working environment requires the material to have higher strength and wear resistance, then 2024 aluminum sheet may be a better choice.
