Precision slit aluminum coil is processed through a precision slitting process into aluminum strips of specific widths. Featuring high precision and high performance, aluminum slit coils are widely used in a variety of industries, including electronics, automotive, construction and aerospace. Cutting is typically performed using a hydraulically driven circular blade, with width set via a PLC system. A laser positioning and calibration system precisely positions and aligns the rolled aluminum coil sheet to ensure cutting accuracy. After slitting, the sheet can be laminated to prevent damage during transportation.
Common Specifications
Thicknesses generally range from 0.1-6.0mm, and widths from 10-1900mm. Customization is possible.
Product Features of Slit Aluminum Coil:
- High Precision:
Width tolerances are controlled within ±0.05mm, edge burrs are ≤0.05mm, and flatness is <0.03mm/m, meeting high-precision processing requirements.
- Diverse Materials:
Covering aluminum alloys from series 1000 to 7000, such as the 1xxx pure aluminum series, which offers excellent ductility and conductivity and is suitable for electrical applications; the 3xxx rust-resistant aluminum series, which offers excellent corrosion resistance and is commonly used in construction and the chemical industry; and the 5xxx high-magnesium aluminum series, which offers high strength and toughness and is used in automotive and aerospace applications.
- Excellent Performance:
Featuring lightweight, high strength, corrosion resistance, and excellent thermal and electrical conductivity, it effectively reduces product weight and improves performance and service life.
The production process for precision slit aluminum coils typically includes the following key steps:
- Ingot Melting and Casting:
The appropriate aluminum alloy is selected, melted, and then cast into ingots.
After cooling, the ingots undergo heat treatment to enhance their mechanical properties.
- Hot Rolling:
The ingots are heated to an appropriate temperature and rolled into thinner coils through a hot rolling process.
The hot rolling process refines the aluminum's microstructure and enhances its ductility.
- Cold Rolling:
The hot-rolled aluminum coils are further cold-rolled to achieve the desired thickness and surface quality. Cold rolling increases the strength and hardness of aluminum coils while also improving their surface finish.
- Annealing:
After cold rolling, aluminum coils typically undergo annealing to eliminate internal stresses and improve the material's plasticity and processing properties.
The annealing temperature and time are adjusted according to the characteristics of the aluminum alloy.
- Precision Slitting:
The annealed aluminum coils are placed in a slitting machine and precision-cut to the customer's desired width.
During the slitting process, the cutting speed and pressure must be controlled to ensure smooth edges and precise widths.
- Surface Treatment:
Based on customer requirements, the slitted aluminum strip may require surface treatment, such as anodizing, coating, or cleaning, to enhance corrosion resistance and aesthetics.
- Inspection and Packaging:
The slitting aluminum strips are quality inspected to ensure compliance with standards.
During packaging, appropriate materials are used to protect the strips from damage during transportation.
Applications of Slit Aluminium Coil:
- Automotive Industry:
Used in battery housings, body structural components, suspension systems, and other applications, they achieve lightweighting and improve collision energy absorption, meeting the needs of new energy vehicle development.
- Electronics Industry:
It serves as a base material for capacitor casings and resistor leads, leveraging its excellent conductivity, corrosion resistance, and ease of processing to protect internal components and simplify production processes.
- Construction Industry:
It can be used in curtain wall components, decorative moldings, and roof waterproofing and insulation. After surface treatment, it exhibits excellent UV and acid rain resistance, making it suitable for use in a variety of harsh environments.
- Transportation Industry:
It can be used to produce license plates and traffic signs, offering strong weather resistance and fading resistance.
