5/23/2025 Color Coated Aluminum Coil Aluminum Substrate Price:CNY 20,350/Mt - Aluminum Market Trend

SMM A00 Aluminum Ingot(CNY/mt)

On May 23, the price of SMM A00 aluminum unchange compared with the previous trading day.Aluminum Ingot inventory continued to decrease by 30,000 tons to 557,700 tons, and continued inventory reduction supported prices. At present, the market demand trend of photovoltaic profiles is on a downward trend, mainly due to the weakening of photovoltaic production. The aluminum sheet and foil market has basically entered the seasonal off-season, and orders have declined. However, the rush to export terminal products has a relatively limited direct impact on domestic aluminum sheet and foil orders. Terminal companies mostly use the inventory purchased in the early stage to meet shipment needs. On the macro level, due to the strong export expectations brought about by the easing of the Sino-US trade war, the short-term macro pessimistic expectations have been reversed, but the expectation of a decline in global demand brought about by the medium-term trade war still exists.

What is the important of curing Colored aluminum Coil?

Enhance coating adhesion

Curing allows the resin, solvent and additives in the coating to fully cross-link, thereby improving the bonding between the coating and the aluminum substrate, preventing peeling or blistering, and increasing service life.

Improve weather resistance and corrosion resistance

A fully cured coating can form a dense protective film, which enables the color coated aluminum coil to resist the erosion of ultraviolet rays, moisture, acid rain and chemicals, and is particularly suitable for outdoor building materials (such as roofing, curtain walls, etc.).

Optimize physical properties

A properly cured coating for colored aluminum coil can significantly improve wear resistance, impact resistance, hardness and flexibility, making it less likely to crack or peel during processing (such as bending and stamping).

Ensure color stability

Proper control of temperature and time during the curing process can prevent color difference problems, ensure color consistency between product batches, and avoid discoloration or fading of the coating due to insufficient curing.

Improve product processing performance

Well-cured coatings perform better in subsequent processing (such as shearing, bending, stamping, and lamination), are less likely to have coating cracks, peeling, and other problems, and improve production efficiency and finished product quality.
