How do fluctuations in aluminum ingot prices affect the aluminum profile final cost?

1. Understanding the Role of Aluminum Ingots

Before any WJW aluminium profile is shaped, cut, or coated, it starts as an aluminium ingot — a solid block of refined aluminium metal. These ingots are melted down and extruded into various profile shapes used for window frames, door systems, curtain walls, and structural components.

The cost of aluminium ingots typically accounts for 60–80% of the total production cost of an aluminium profile. That means when ingot prices rise or fall, manufacturers must adjust their selling prices to reflect the change.

For instance:

If the aluminium ingot price rises from USD 2,000/ton to USD 2,400/ton, the production cost for a 500 kg order could increase by over 20%.

Conversely, when ingot prices drop, manufacturers may offer more competitive pricing to customers.

2. How the Global Market Influences Ingot Prices

Aluminium ingot prices are determined by global supply and demand, primarily traded on international markets such as the London Metal Exchange (LME).

Several major factors influence these fluctuations:

a. Energy Costs

Aluminium smelting is an energy-intensive process — electricity can account for up to 40% of production costs. Rising energy prices (for example, due to fuel or power shortages) often lead to higher ingot costs.

b. Raw Material Availability

Aluminium is refined from bauxite ore, and any disruption in bauxite mining or alumina refining can reduce supply, pushing ingot prices upward.

c. Global Demand

Industrial growth in countries like China, India, and the U.S. significantly affects global demand. When construction, automotive, or aerospace industries boom, aluminium demand surges — and so do ingot prices.

d. Economic and Political Events

Trade policies, tariffs, or geopolitical tensions can also impact aluminium prices. For example, export restrictions or sanctions may limit supply and increase costs worldwide.

e. Exchange Rates

Since aluminium is traded in U.S. dollars, currency fluctuations affect local prices in other countries. A weaker local currency makes imported aluminium more expensive.

3. The Connection Between Ingot Price and Aluminium Profile Cost

Now let’s explore how this directly impacts the WJW aluminium profile you purchase.

Step 1: Raw Material Cost

The ingot price determines the base cost of extrusion. When ingot prices go up, so does the cost per kilogram of aluminium profile.

Step 2: Extrusion and Fabrication

The extrusion process involves melting ingots, forming them into profiles, and cutting them to size. While fabrication costs (labor, machinery, quality control) remain relatively stable, the overall cost rises when raw material prices increase.

Step 3: Surface Treatment

Processes like anodizing, powder coating, or fluorocarbon painting add to the final cost. These costs may not change drastically with ingot prices, but the total product price still rises because the base aluminium becomes more expensive.

Step 4: Final Quotation

The final quotation you receive from a WJW Aluminum manufacturer combines:

Base ingot cost

Extrusion and fabrication costs

Finishing and packaging costs

Logistics and overhead

So, when ingot prices rise, manufacturers must adjust their quotes accordingly to maintain profitability.

As you can see, even a 20% increase in ingot price can result in a 14% rise in the final aluminium profile cost.

For large construction or export projects, this difference can be significant — which is why understanding market timing and supplier transparency is so important.
