Mill Finish Aluminium Sheets & Coils

1. Aluminium Sheets: Typically ranging from 0.2mm to 6mm in thickness, sheets are used in applications like automotive panels, building facades, and packaging.
2. Aluminium Plates: With thicknesses greater than 6mm, plates are ideal for heavy-duty applications such as aerospace, military, and marine industries.
3. Aluminium Foils: Thinner than 0.2mm, foils are commonly used in packaging, insulation, and electrical applications.

Flat rolled aluminium products are available in various alloy compositions, each tailored for specific properties and applications. Here are some common alloy series and their characteristics:

Mill-finish aluminum products are used in a wide range of industries. Some common applications include:

• Architectural and Construction: Mill-finish aluminum sheets and coils are often used in the construction of facades, roofing, siding, and cladding. It’s also used in structural applications like window frames, doors, and curtain walls. In some cases, mill-finish aluminum is used as-is, while in others, it’s further treated for appearance or protection (e.g., anodizing or powder coating).
• Automotive: Mill-finish aluminum is used in the automotive industry for components such as body panels, structural elements, and heat exchangers. It’s valued for its strength-to-weight ratio and durability.
• Packaging: Aluminum foil products are sometimes supplied in a mill-finish form, especially in applications like food packaging where a further finish is not required.
• Electrical: Mill-finish aluminum is also used in electrical applications, including conductors, bus bars, and components for electrical circuits due to its high electrical conductivity and resistance to corrosion.
• Consumer Products: Some consumer products, like kitchen appliances, cookware, and electronics, can be made from mill-finish aluminum, especially if further surface treatment is not necessary.

• Cost-Effective: Because mill-finish aluminum hasn’t undergone additional finishing steps, it is often less expensive than anodized, painted, or polished aluminum products.
• Corrosion Resistance: Even in its raw state, aluminum’s natural oxide layer provides inherent corrosion resistance, making it suitable for outdoor and exposed applications.
• Versatility: Mill-finish aluminum is available in a range of alloys, offering a good balance of strength, formability, and corrosion resistance for many industries.
• Ease of Further Processing: Mill-finish aluminum can be easily further processed (e.g., anodizing, powder coating, or polishing) depending on the needs of the specific application.

Mill-finish aluminum products can be further processed to improve their aesthetic or functional properties:

• Anodizing: An anodized aluminum finish enhances the natural oxide layer, providing increased corrosion resistance and allowing for color options. It also improves surface hardness and durability.
• Powder Coating: Aluminum sheets and coils can be powder-coated to improve appearance, provide color, and offer additional corrosion resistance.
• Polishing: Some mill-finish aluminum products are polished to a shiny, mirror-like finish for decorative applications.
• Painting: Mill-finish aluminum can be painted for additional protection and aesthetic improvement.
