8.what is the most common aluminum alloy for machining?
The material we commonly used are Al3003, Al5052, Al6061, Al7075 and cast material ADC12.
1. Aluminum 3003 material main component is manganese. It has good anti-rust function. Aluminum parts made by Al3003 are widely used in humid environments, such as air conditioner, refrigerator and car bottom.
2. Aluminum 5052 material main element is magnesium.We also call it aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series at the same condition. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries.
3. Aluminum 6061 material mainly contains two elements of magnesium and silicon. It has excellent interface characteristics, easy coating, high strength, good workability, strong corrosion resistance. It is typically used for aircraft parts, camera parts, couplers, marine parts and hardware, electronic parts and fittings, decorative or various hardware, hinged heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves and valve parts
4. Aluminum 7075 material mainly contains zinc element. It also belongs to the aviation series. Aluminum 7075 is aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not be deformed or warped after processing. All super big and super thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve the working efficiency. The main feature is that 7075 is high hardness and high strength aluminum alloy. It mainly used in the manufacture of aircraft structures or other aluminum parts require high-strength, corrosion-resistant high-stress structural parts, mold manufacturing.
