Aluminum sheet h24 price manufacturers

The H24 temper indicates that the aluminum has been strain-hardened and then partially annealed to a half-hard state. This process ensures the material achieves a specific balance of strength and ductility, making it easier to bend or form without cracking compared to fully hardened (H18) tempers. It is commonly applied to alloys like 3003, 5052, and 5754.

Pricing is primarily driven by the Alloy Grade (e.g., 5052 is more expensive than 3003 due to magnesium content), Thickness Tolerance (precision rolling increases cost), and Surface Finish (mill finish, brushed, or anodized). Buyers should specify ASTM B209 or EN 485 standards to ensure quality consistency, as deviations in thickness can lead to significant material waste in high-volume production.

Due to its excellent corrosion resistance and formability, H24 aluminum is widely used in architectural cladding, signage, fuel tanks, and automotive body panels. In the HVAC industry, it is preferred for heat exchangers because it maintains structural integrity while allowing for the necessary mechanical expansion and contraction.

Buyers must request a Mill Test Certificate (MTC) that includes the chemical composition analysis and mechanical property tests (tensile strength, yield strength, and elongation). For international trade, ensure the supplier complies with ISO 9001:2015 for manufacturing processes and SGS or TUV third-party inspections for batch consistency.

The price is usually structured as [LME (London Metal Exchange) Aluminum Ingot Price] + [Fabrication/Processing Fee]. Because the LME price fluctuates daily, quotes are often valid for only 24 to 72 hours. To mitigate price volatility, buyers should consider long-term framework agreements or use Made-in-China.com's secured payment services to lock in rates during the transaction period.

The biggest risk is oxidation (white rust) caused by moisture during sea transit. Ensure the supplier uses seaworthy packaging, including waterproof paper, plastic film, and silica gel desiccant, all secured on fumigated wooden pallets. For high-value H24 sheets, specify 'Eye to Sky' or 'Eye to Wall' loading orientations to prevent physical deformation during crane handling.

Focus on Volume-Based Tiered Pricing. For orders exceeding 5-10 tons, fabrication fees can often be reduced by 10-15%. Additionally, negotiate the weight tolerance (theoretical weight vs. actual scale weight) to avoid paying for excess material. Professional buyers on Made-in-China.com often request free samples to test the bending radius of the H24 temper before committing to a full container load.

Buyers must check for Anti-Dumping Duties (ADD) and Countervailing Duties (CVD) in their specific country (e.g., US or EU) against Chinese aluminum products. Utilizing the Correct HS Code (typically 7606) is vital for accurate duty calculation. Working with a supplier who provides a Certificate of Origin (CO) can help in claiming preferential tariff rates under specific Free Trade Agreements.
