SMM A00 Aluminum Ingot(CNY/mt)

On June 20th, the price of SMM A00 aluminum dropped by CNY 70/Mt compared with the previous trading day.LME closed at 2525.5 on the previous trading day, down 19.5 or 0.77% on the day. The internal divisions in the United States and the risk of war in the Middle East have increased. The rise in crude oil prices has pushed up the cost of overseas aluminum, but demand concerns have suppressed sentiment. Domestic aluminum inventories are still at a multi-year low. In addition, there are signs of marginal easing of US steel and aluminum tariffs (implementing most-favored-nation tariffs on the UK), and aluminum prices may still rise. The destocking of aluminum social inventories has slowed down. The domestic social inventory of aluminum ingots was recorded at 449,000 tons, a decrease of 9,000 tons from Monday and 11,000 tons from last Thursday. The inventory of aluminum bars was 135,000 tons, an increase of 3,000 tons from Monday and 7,000 tons from last Thursday. The processing fee of aluminum bars rebounded yesterday. Yesterday, the LME aluminum inventory was 345,000 tons, a decrease of 2,000 tons from the previous month.

Why is 3003 colored aluminum coil more suitable for use in humid environments?

Superior Alloy Composition

 

3003 color coated aluminum coil belongs to the aluminum-manganese (Al-Mn) series, with a manganese content of 1.0%–1.5%. It significantly enhances its corrosion resistance and structural stability in acidic or mildly alkaline environments, effectively slowing down the corrosion process.

More Stable Oxide Film

 

The surface of aluminum naturally forms a oxide filom, which effectively prevents erosion from external acidic or alkaline substances.In 3003 color coated aluminum coils, the presence of manganese and other trace elements improves the integrity and stability of this oxide layer, further enhancing corrosion resistance.

Low Copper Content

 

Copper reduces corrosion resistance in acidic and alkaline environments. The low copper content in 3003 color coated aluminum coil helps maintain its corrosion-resistant properties in such conditions.
