3003 3004 3015 H12 Aluminium Coils
Aluminium has paved its way as an essential material across various industries, notable for its versatility, durability, and lightweight characteristics. Among the multitude of aluminium alloys, the 3000 series stands out, especially the widely utilized 3003, 3004, and 3015 H12 grades.
The Foundation: Aluminium Alloy Series 3000
The 3000 series aluminium alloys are known for their excellent corrosion resistance, weldability, and suitability for electrical applications. They consist primarily of manganese as the alloying element, which adds strength without compromising the inherent flexibility of aluminium.
3003 H12 Aluminium Coils
3003 Aluminium Coil is one of the most common and widely used grades of the 3000 series. Characterized by its alloy composition holding about 1.0% manganese, 3003 is lightweight while exhibiting good workability and moderate strength.
Properties and Specifications:
- Alloy Composition: 96.5% to 99% aluminium, 1.0% manganese.
- Size: Thickness options typically ranging from 0.5 mm to 3.0 mm.
- Mechanical Properties:
- Yield Strength: About 100-116 MPa.
- Tensile Strength: Around 130-150 MPa.
The excellent formability allows it to be made into intricate forms that other materials cannot accommodate. The durability of 3003 coils makes it a favorite in heating and cooling equipment like heat exchangers.
3004 H12 Aluminium Coils
3004 Aluminium Coil incorporates an increased specification from 3003, primarily formed with about 1.0% manganese and a hint of magnesium.
Properties and Specifications:
- Alloy Composition: Roughly 95.7% to 98% aluminium, 1.0% manganese, and small quantities of magnesium.
- Size: Thin plates often range similarly from 0.5 mm up to about 4.0 mm, catering more effectively to varying industry needs.
- Mechanical Properties:
- Yield Strength: Approximately 185-200 MPa.
- Tensile Strength: About 240-310 MPa.
The additional strength gives 3004 an edge, especially in manufacturing beverage cans and architectural features, making it notably suitable for deep drawing. It can withstand higher pressures, transforming everyday items into highly efficient products.
3015 H12 Aluminium Coils
3015 Aluminium Coil belongs to the slightly advanced section of the 3000 series applying standardising elements that enhance its utility.
Properties and Specifications:
- Alloy Composition: Approximately 90.0%-93.71% aluminium with slight iron, silicon, and copper for reinforcement.
- Size: Variable thickness ranging similar to its predecessors but tends to be customizable.
- Mechanical Properties:
- Yield Strength: Should meet slightly elevated standards similar to 3004 but examined for specific applicable shutdowns.
- Tensile Strength: Approaching strengths comparable to advanced 3000 series grades.
It offers a blend of agricultural functionality and aesthetics with its improved strength scenario, placing emphasis on both creativity in usage and solid reliability under duress.
Implementation Standards & Tempering Conditions
Each of these alloys conforms to rigorous industrial implementation standards, assuring users of ultimate quality and dependability. Common standards pursued include ASTM B209 for aluminum and composed products relevant to shape and thickness, ensuring adequate detection of imperfections and structural abnormalities.
Tempering Conditions – H12 Temper
The 'H' designation in H12 refers to "Strain-Hardened" conditions, cataloging several treatments related to dislocation manipulations which endockets precise gird requirements while tempering. It retains better elongation properties while remaining firm in its applications and turning shapes.
- H12 Provisions:
- Suitable for producing coils that maintain their form under stress.
- Medium strain specifications upon fabrication provide easy manageability for further manufacturing processes.
