The beverage can is a marvel of modern engineering. Its lightweight, durable, and recyclable body relies on a specific high-performance material. That material is often can materials 3104 H19 aluminum coil. This article explores why this alloy is the industry standard and what to consider when sourcing it.
3104 coil is an aluminum-manganese-magnesium alloy. The “H19” temper means it is strain-hardened to the hardest achievable state. This gives it a unique balance of high strength and good formability. These properties are critical for can manufacturing.
Superior Deep-Drawability: It allows for smooth, high-speed forming into can bodies without cracking.
Strength and Lightweighting: H19 temper provides high yield strength. This enables thinner wall gauges, reducing material use and cost.
Excellent Surface Quality: The coil surface is uniform and clean. It is perfect for high-quality printing and coating.
Food Safety: The alloy is safe for food and beverage contact. It meets all relevant standards.
Pay close attention to these parameters:
* Thickness & Tolerance: Common thickness ranges from 0.010″ to 0.012″ (approx. 0.265mm-0.30mm). Consistent, tight tolerance is vital for production stability.
* Width & Coil Diameter: Ensure the dimensions match your production line requirements. Reliable suppliers (MINGTAI ALUMINUM) offer customizable sizes.
* Mechanical Properties: Key metrics include Tensile Strength, Yield Strength, and Elongation. Consistent lot-to-lot performance ensures smooth production.
Proper handling protects your material investment and production quality.
* Storage: Store coils indoors in a dry, well-ventilated area. Avoid extreme temperature and humidity changes. Use proper padding to prevent edge damage. Keep coils away from contaminants.
* Handling & Transportation: Always use appropriate lifting equipment (e.g., a mandrel or C-hook). Never lift with slings that can damage the coil eye. Avoid impacts during loading and unloading. Secure coils firmly during transport to prevent movement.
Following these practices maintains the pristine quality of the Can Materials 3104 H19 aluminum coil from your supplier to your press line.
Q1: What’s the main difference between 3104 and 3004 for can bodies?
A1: 3104-H19 offers higher strength than 3004. This allows for lighter, thinner can walls while maintaining required strength, making it the standard for two-piece beverage can bodies.
Q2: What are the most critical quality checks for this coil?
A2: Focus on consistent mechanical properties (yield strength, elongation) and superior surface quality. These directly impact forming performance and final can appearance.
Q3: Can we get customized coil dimensions?
A3: Yes. Professional suppliers can provide coils tailored to your specific thickness, width, and diameter requirements for optimal line performance.
Q4: What is the typical lead time?
A4: Lead time depends on order volume and specifications. Contact suppliers directly with your detailed needs for an accurate production and delivery schedule.
