SMM A00 Aluminum Ingot(CNY/mt)
On June 19th, the price of SMM A00 aluminum dropped by CNY 130/Mt compared with the previous trading day.The internal divisions in the United States and the risk of war in the Middle East are increasing. Be wary of the impact of short-term geopolitical events on the market. The geopolitical situation overseas has been repeated. The rise in crude oil prices has pushed up the cost of overseas aluminum, but demand concerns have suppressed the sentiment, and aluminum prices may still rise. According to SMM statistics, the inventory of aluminum ingots continued to decrease month-on-month, but the destocking rate was significantly narrowed. We still need to pay attention to the inventory pressure caused by weak consumption. The inventory of aluminum bars declined slightly and the processing fee fell sharply, and the demand margin weakened. Yesterday, LME aluminum inventory was 347,000 tons, a decrease of 2,000 tons month-on-month. China's alumina plants continue to resume production. The uncertainty of Guinea's ore policy and the problem of shipping from several mines in the rainy season are logically likely to increase alumina prices. The demand structure of electrolytic aluminum has further differentiated, aluminum exports increased in May, and there is resilient support for unshipped orders in June.

What should be considered when purchasing colored aluminum coils?
Aluminum alloy Series and Tempers
When purchasing color coated aluminum coils, it is important to comprehensively consider the application environment, load-bearing requirements, processing needs, and performance criteria. Selecting the appropriate aluminum alloy and temper for the substrate is crucial, along with attention to substrate thickness. For example, a 0.9mm thick 3004 H24 colored aluminum coil is ideal for railway project roofing due to its excellent durability.
Coating Types and Thickness
The type and quality of the coating directly impact the appearance and protective performance of the color coated aluminum coil. Coating types should be selected based on the application environment and requirements. Common coating types include PE, HDP, SMP, and PVDF. PE coatings are suitable for relatively mild environments, PVDF coatings are ideal for applications requiring superior durability and corrosion resistance. In addition to the coating type, coating thickness also affects processing and application. Too thin coating may lack adequate protection, leading to fading, chalking, and other issues. Conversely, too thick coating can negatively impact processing performance.
Performance Indicators
After production, colored aluminum coils should be tested according to ASTM standards for thickness, flexibility, impact resistance, abrasion resistance, and coating adhesion. These tests determine the coil's performance and durability in actual applications. A common method for testing adhesion is the cross-cut test.
Appearance Quality
The appearance quality of the coil directly affects its performance and aesthetics in use. Attention should be paid to whether the color consistency and gloss meet standards, whether the surface is smooth, and whether there are defects such as scratches or dents.
Supplier Qualifications
Selecting a colored aluminum coil supplier with strong qualifications and a good reputation is essential to ensure high-quality products. The supplier should meet production and quality standards and possess relevant production licenses and quality certifications (such as ISO quality management system certification). Additionally, their production capacity, product quality, delivery time, and after-sales service should be assessed to ensure they can meet high service expectations.
Contract Terms
When signing a sales contract with the supplier, it is critical to clearly specify detailed parameters such as the specifications, substrate material, coating type and thickness, and performance indicators of the colored aluminum coils. Ambiguous descriptions should be avoided. The contract should also clearly state delivery time, delivery location, and transportation method to ensure a smooth procurement process.
