SMM A00 Aluminum Ingot(CNY/mt)

On June 17th, the price of SMM A00 aluminum dropped by CNY 20,610/Mt compared with the previous trading day.US inflation is lower than expected, boosting the Fed's expectations of rate cuts, but the escalation of tensions in the Middle East has increased risk aversion in the market, and the US dollar index has rebounded. The Fed's interest rate meeting is about to take place this week, and uncertainty remains strong. LME weekly inventory reduction was 10,625 tons to 353,200 tons. As of June 16, the inventory of electrolytic aluminum in major Chinese markets was 460,000 tons, a decrease of 3,000 tons from the inventory last Thursday. The social inventory of aluminum ingots continued to fall over the weekend. The inventory of aluminum ingots fell to 460,000 tons last week. Since entering June, it has maintained a weekly destocking rhythm of 40,000 tons, but aluminum bars have stopped destocking, indicating that the increase in the proportion of aluminum liquid has led to a decrease in ingots. The main reason, but the rapid destocking of total inventory has strengthened the support for aluminum prices. The inventory of aluminum ingots at home and abroad maintains a destocking trend, the overseas aluminum spot basis has turned into a premium, the social inventory of domestic aluminum ingots continues to decline, and with the rebound in prices, the willingness of downstream to pick up goods may weaken in the short term, the supply and demand fundamentals are weakening, and aluminum prices are under pressure.

Excellent Weather Resistance:.PVDF colored aluminum coil resist UV radiation, acid rain, humidity, and temperature extremes, preventing chalking, fading, and corrosion.It can keep its color and gloss for 30 years without the need for repainting or surface treatment.
Excellent Color Retention: PVDF colored aluminum coil resins maintain color stability for 30+ years, even in extreme climates. This is crucial for exterior architectural applications where aesthetics must remain consistent over time.
Strong Chemical Resistance: PVDF colored aluminum coil is highly resistant to pollutants, industrial fumes.It can prevent surface degradation even in aggressive chemical environments.
High Flexibility and Adhesion:PVDF colored aluminum coil form a tough, flexible film that adheres strongly to the aluminum substrate, reducing the risk of peeling or cracking during bending or fabrication.
Low Maintenance Requirements:  PVDF colored aluminum coil is hydrophobic, so dust, dirt and debris do not adhere easily and are usually washed away naturally by rain. Its corrosion and weather resistance also allows the application to maintain its color and gloss without the need for regular maintenance.

 

How to choose the right coating for colored aluminum coils

 

 

When choosing the colored aluminum coil coating, you need to comprehensively consider the application environment, performance requirements, and cost budget to choose the most suitable coating.
