Welcome to Hemaokang Steel (Shandong) Co., Ltd. — a reliable supplier of high-quality marine-grade aluminum plates tailored for the demanding boat building industry. Our 5052-H32 Aluminum Plate in thicknesses from 1mm to 6mm offers exceptional corrosion resistance, excellent weldability, and superior strength-to-weight ratio, making it the preferred choice for hulls, decks, and superstructures. Backed by our ISO9001 certified production facility and annual export value exceeding US$50 million, we ensure consistent quality and timely delivery to global markets.
Product Features & Technical Specifications
- Marine-Grade Corrosion Resistance — The 5052 alloy contains magnesium as the primary alloying element, providing excellent resistance to saltwater, chloride, and other harsh marine environments.
- Optimal Strength & Formability — H32 temper offers a balanced combination of strength (tensile strength 210–260 MPa) and workability, allowing easy bending, cutting, and forming without cracking.
- Wide Thickness Range — Available from 1mm to 6mm, suitable for lightweight boat components or structural panels requiring moderate load-bearing capacity.
- Excellent Weldability — Can be welded using MIG, TIG, and resistance welding methods without significant loss of corrosion resistance, ideal for complex boat assemblies.
- Precise Dimensional Tolerances — Manufactured in accordance with ASTM B209 and EN 485 standards, ensuring flatness, thickness uniformity, and accurate cut-to-size lengths.
- Customizable Sizes & Surface Finishes — We offer custom widths (1000–2500mm), lengths (2000–12000mm), and surface options such as mill finish, bright finish, or embossed patterns.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 5052-H32 and 5052-H34?
A: H32 indicates a strain-hardened temper with a moderate level of work hardening, while H34 has a higher strength but lower formability. H32 is more commonly used in boat building due to its excellent balance of strength and ductility.
Q2: Can this plate be used for freshwater boats as well?
A: Yes, 5052-H32 is suitable for both saltwater and freshwater environments. Its corrosion resistance is superior to many other 5xxx series alloys, making it versatile for various watercraft.
Q3: What standard sizes do you stock?
A: We commonly stock widths of 1220mm, 1500mm, and 2000mm, and lengths of 2440mm, 3000mm, and 6000mm. Custom sizes are available upon request with shorter lead times.
Q4: Do you provide cutting or slitting services?
A: Yes, we offer custom cutting (shearing, sawing) and slitting to your specified dimensions. Please inform your required width and length when placing an order.
Q5: Is the plate suitable for welding with other aluminum alloys?
A: 5052 has good weldability with common filler metals such as ER5356 or ER5183. It is compatible with most 5xxx and 6xxx series alloys, but we recommend consulting our technical team for specific joint designs.
Q6: What is the typical lead time for a 20ft container order?
A: For standard sizes, the lead time is approximately 15–20 working days after deposit confirmation. Custom sizes may require 25–30 working days, depending on the complexity.
Q7: Do you supply samples for testing?
A: Yes, we provide free samples (A4 size or 200x200mm) for quality evaluation. Buyers only need to pay the shipping cost. Contact our sales team to arrange sample delivery.
Q8: How do you pack the plates to prevent damage during transit?
A: Our plates are packed with plastic film, kraft paper, and steel strapping, then placed on wooden pallets with edge protectors. For sea freight, we use waterproof woven bags and fumigated wooden crates to ensure safe arrival.
