Underwater and marine applications

Underwater and Marine Application

Magnesium alloy has many superior properties in underwater and marine applications, so it is widely used in shipbuilding, submarine components, underwater camera accessories, and other areas. Here are some details of its application in these fields:

Magnesium alloy ship plate: Magnesium alloy ship plates have the characteristics of high strength, lightweight, and corrosion resistance. They can reduce the weight of the ship's hull, improve speed and stability, and also reduce fuel consumption.

Magnesium alloy ship propeller: Magnesium alloy ship propellers have the characteristics of high strength, low density, and corrosion resistance, which can greatly reduce operational noise and improve the propulsion efficiency of ships.

Magnesium alloy submarine components: Magnesium alloy submarine components have the characteristics of lightweight, high strength, and corrosion resistance. They can reduce the total weight of submarines and improve their speed and flexibility.

Magnesium alloy underwater camera accessories: Magnesium alloy underwater camera accessories have high corrosion resistance and sealing performance, and are suitable for use in underwater environments such as deep-sea detection.

Ship-use magnesium alloy screws: Ship-use magnesium alloy screws have the characteristics of corrosion resistance and resistance to seawater erosion, and can be used for long periods in harsh marine environments. They are suitable for shipbuilding and maintenance.

Different underwater and marine applications have different requirements for the properties of magnesium alloy, so the selected magnesium alloy grade will also vary depending on the specific application. Here are some common magnesium alloy grades and their applicable ranges:

AZ31B: AZ31B magnesium alloy has the characteristics of lightweight, high strength, good plasticity, and corrosion resistance, and is suitable for the manufacture of ship plates, ship propellers, etc.

WE43: WE43 magnesium alloy has high strength and excellent corrosion resistance, and is suitable for the manufacture of submarine components, underwater camera accessories, etc.

AZ91D: AZ91D magnesium alloy has high strength and compression performance, and is suitable for the manufacture of anchor chains, ship-use screws, etc.

The specifications and thread types of magnesium alloy ship plates, magnesium alloy ship propellers, magnesium alloy submarine components, magnesium alloy underwater camera accessories, magnesium alloy anchor chains, and ship-use magnesium alloy screws vary according to specific application requirements. Different application fields may require screws with different diameters, lengths, thread shapes, etc. Generally speaking, these products can be manufactured and selected according to national standards (GB), industry standards (JB), American standards (ANSI), or German standards (DIN).

Here are some common magnesium alloy screw specifications and thread types:

Ship-use magnesium alloy screws: M5-M20, UNC or UNF thread type.

Magnesium alloy underwater camera accessories: M4-M10, UNC or UNF thread type.

Magnesium alloy anchor chain: M6-M24, UNC or UNF thread type.

Magnesium alloy ship plate: Usually specified by thickness and length, such as a standard size of 6mm x 2000mm x 6000mm.

Magnesium alloy ship propeller: Usually specified by diameter and pitch, such as a diameter of 2000mm and pitch of 3000mm.

Magnesium alloy underwater camera accessories: Usually specified by size and weight, such as dimensions of 120mm x 80mm x 50mm and weight of 500g.

Magnesium alloy anchor chain: Usually specified by diameter and length, such as a diameter of 20mm and length of 100m.

Ship-use magnesium alloy screws: Usually specified by diameter and length, such as M10 x 50mm.
