أنا. مقدمة ل 6061:
6061 في 6000 سلسلة الألومنيوم, المكونات الرئيسية هي المغنيسيوم والسيليكون, وهو ما يمثل نسبة منخفضة من التكوين الإجمالي. قوة الألومنيوم أقل من 7005. ولكن لأن تكوين السبائك بسيط, محتوى منخفض, وسهلة اللحام والضغط, وبالتالي فإن السعر رخيص.
العناصر الرئيسية لصناعة السبائك في 6061 سبائك هي المغنيسيوم والسيليكون, التي لديها قوة معتدلة, مقاومة جيدة للتآكل, قابلية اللحام, and good oxidation effect. It is widely used in all kinds of industrial structures requiring certain strength and high antibiotic resistance.
6061 is the most common aluminum, with light weight, قوة, and economic benefits.
Ⅱ. 7075 introductions:
7075 is the lightest and strongest aluminum, and it’s super expensive! ال 7075 is strong as steel.
7075 aluminum sheet is a high-strength cold working forged alloy, far superior to low carbon steel. 7075 is one of the strongest alloys commercially available. General corrosion resistance, خصائص ميكانيكية جيدة, and anodic reaction. Fine grains make deep drilling performance better, tool wear resistance enhanced, and wire rolling is different from weight.
The high-end 7075 aluminum plate belongs to Al-Zn-MG-Cu superior aluminum. 7075 alloy is a kind of ultra-high strength deformation aluminum alloy, which has been used in aircraft manufacturing since the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, excellent heat treatment strengthening effect, high strength below 150℃, and excellent strength at low temperatures. Poor welding performance; There is a tendency for stress corrosion cracking. It needs to be applied with an aluminum coating or other protective treatment. The stress corrosion cracking resistance of the alloy can be improved by double-stage aging.
According to China’s executive standard: غب / ت 3880.2-2006, solid solution stability, good plasticity after treatment, has a particularly good heat treatment strengthening effect. The super strong 7075 is also known as steel.
سبائك الألومنيوم 7075 سبائك الألومنيوم, zinc is the main alloying element. It is powerful, and comparable in strength to many sheets of steel, with good fatigue strength and general machining properties, but it is poorly resistant and more corrosive than many other aluminum alloys. Its relatively high cost limits its use. Cheap alloys are not suitable for the application.
ال 7075 is also a 7000 سلسلة الألومنيوم. It has the same composition as 7005, but is much higher in content and much harder than 6061. Beyond the hardness of steel. But because the alloy composition is many, the hardness is very high. So welding and pressing are difficult. The price is also much higher than 6061 و 7005.

Ⅲ. 6061 و 7075 difference:
1. Differences in ingredients:
6061 سبائك الألومنيوم, aluminum alloy accounted for 97.9%, magnesium accounted for 1%, silicon accounted for 0.6%, but also added 0.28% copper and 0.2% الكروم.
The composition of 7075 سبائك الألومنيوم تشمل تقريبا 5.6-6.1%, 2.1-2.5% الزنك, 1.2-1.6% المغنيسيوم, نحاس, السيليكون, حديد, المنغنيز, التيتانيوم, chromium and other metals. It is usually produced in several grades of thermal states, 7075-يا, 7075-T6, and 7075-T651.
2. Hardness difference:
صلابة 6061 is 90HB.
7075 hardness up to 150HB.
3. Series differences:
6061 in a 6000 سبائك الألومنيوم سلسلة.
7075 في 7000 سبائك الألومنيوم سلسلة, is zinc magnesium-aluminum alloy.
4. Different mechanical properties:
أَثْمَر, shear, and tension of aluminum alloys
Code (أَثْمَر)(Shear)(الشد)
6065 7KSI 10KSI 13KSI
7075 15KSI 22KSI 33KSI
Aluminum alloy code: yield, shear, tensile.
6061 7KSI 10KSI 13KSI
7075 15KSI 22KSI 33KSI
6061 – T6 31 ksi 17 ksi 35 ksi
7075 – T6 73KSI 48KSI 83KSI
5. Differences in usage:
Because of the price, ال 6061 can be used in a variety of places that do not need aluminum alloy materials, while the 7075 و 7005 are usually used in aerospace, صلابة عالية, كثافة قليلة, and other commercial purposes. لذا 7075 is usually also a commercial aluminum alloy.
6. Price difference:
ال 6061 aluminum plate price is generally 30 yuan 18-1kg, وسعر 7075 is generally at 60 yuan 40-1kg. وبالتالي, the sales volume of 6061 is relatively high, while the sales volume of 7075 is less than that of 6061 because of the price.
