Aluminum Plate Price

Aluminum is classified as a non-ferrous metal because it is not based on iron but on aluminum as the primary element. This fundamental difference leads to a pricing system that is strongly influenced by global metal markets, alloy composition, and weight-based calculation.

Product Details

The price of aluminum plate is influenced not only by production cost and market demand, but also by the fundamental nature of aluminum as a non-ferrous metal. Understanding this classification helps explain why aluminum behaves differently from steel in both pricing and material properties.

Why Aluminum Is a Non-Ferrous Metal

Aluminum belongs to the category of non-ferrous metals, which means it does not contain iron (Fe) as the main component.

Key definition:

Ferrous metals → mainly contain iron (e.g., carbon steel, stainless steel)
Non-ferrous metals → do not have iron as base element (e.g., aluminum, copper, zinc, magnesium)

Aluminum is classified as non-ferrous because:

Its base element is aluminum (Al), not iron
It has no iron-based crystal structure
It does not exhibit typical steel magnetism

Basic Composition of Aluminum Plate

Aluminum plates are primarily made from:

Aluminum (Al): main element (>90% to 99% depending on alloy)
Alloying elements: magnesium, silicon, copper, manganese, zinc

These elements are added to improve:

Strength
Corrosion resistance
Formability
Heat treatment performance

Why Non-Ferrous Classification Affects Aluminum Plate Price

Because aluminum is non-ferrous, its pricing system is different from steel:

1. Based on global metal exchange

Aluminum price is linked to LME (London Metal Exchange)
Price changes daily based on global supply and demand

2. Alloying elements are expensive

Magnesium, copper, and zinc increase cost
High-performance alloys (like 7075, 2024, 5083) cost more

3. Energy-intensive production

Aluminum requires electrolytic smelting
High electricity consumption directly affects price

4. Weight-based pricing system

Aluminum plate is usually priced by weight:

$\text{Aluminum Plate Price} = \text{Weight (kg)} \times \text{Price per kg}$ $Aluminum Plate Price$ $=$ $Weight (kg)$ $\times$ $Price per kg$

So even small changes in thickness or density directly affect total cost.

Difference Between Aluminum (Non-Ferrous) and Steel (Ferrous)

Feature	Aluminum (Non-Ferrous)	Steel (Ferrous)
Base element	Aluminum	Iron
Magnetism	Non-magnetic	Usually magnetic
Density	Low (lightweight)	Higher (heavy)
Corrosion resistance	Natural oxide protection	Requires coating or alloying
Pricing system	LME-based, volatile	More production-cost based
