In the field of shipbuilding and marine engineering, 5083 aluminum alloy is widely used as a manufacturing material for key components such as hulls, decks, masts, propellers, etc. due to its excellent seawater corrosion resistance. Its high strength and light weight characteristics not only help reduce the deadweight of ships and improve fuel efficiency, but also enhance the structural strength and safety performance of ships. The 5083 H112 marine aluminum alloy plate produced by MC Aluminum has passed the certification standards of classification societies such as CCS (China Classification Society), DNV (Norwegian Classification Society), and ABS (American Bureau of Shipping).

Introduction to the tempering (heat treatment) state of 5083 H112 aluminum plate:

Among aluminum alloys, "H112" is a special tempering state suitable for non-heat treatment strengthened aluminum alloys (such as 5 series aluminum alloys). It is mainly used for aluminum materials after casting or hot working, and has a certain degree of work hardening, but the hardening degree is low. 5083 H112 state aluminum plate is mainly obtained by temperature controlled rolling and cooling. It has stable performance and is widely used in ships, marine engineering, tank trucks and other fields.

H112 compared with other common status:

Characteristics of H112 tempering state:

Not heat-treated strengthening type: 5083 H112 is mainly naturally cooled after hot rolling, rather than solution treatment + artificial aging (such as T6, T651, etc.).

Moderate mechanical properties: Compared with the O state (complete annealing), the strength of the H112 state is slightly higher, but it still maintains good ductility.

Excellent corrosion resistance: 5083 itself has high seawater corrosion resistance, and the H112 state will not reduce its corrosion resistance due to heat treatment, and is suitable for marine environments.

Good weldability: The H112 state will not produce obvious hardening or softening due to welding, so it is particularly suitable for applications that require welding, such as shipbuilding and storage tanks.

Core features of 5083 H112 marine aluminum plate:

1. Excellent corrosion resistance: 5083 aluminum alloy contains a high magnesium element (about 4.0-4.9%), and exhibits extremely strong corrosion resistance in seawater and chemical environments, which is very suitable for marine and ship applications.

2. High strength: Compared with ordinary aluminum alloys, 5083 is a high-strength type among non-heat-treated alloys, and the H112 state ensures good mechanical properties and stability.

3. Good weldability: 5083 aluminum alloy can be welded, and the performance after welding will not be significantly reduced. It is one of the important materials for shipbuilding.

4. Excellent processing performance: It can be cut, bent, stamped and other processing, suitable for the manufacture of various complex structural parts.

5. Excellent low-temperature performance: It still maintains good mechanical properties in low-temperature environments and is suitable for extreme environment applications.

Application areas:

Shipbuilding (hull, deck, bottom plate)

Marine engineering (offshore platform, pontoon)

LNG storage tanks, pressure vessels

Automobile lightweight (tank trucks, oil tanks)
