Product details

Casting Magnesium Alloy Plate, also known as magnesium alloy casting plate, refers to the plate made through the casting process of magnesium alloy material. Magnesium is a lightweight, high-strength, corrosion-resistant metal element, so the cast magnesium plate has a light weight, good strength, good vibration-damping performance, etc., and is commonly used in automotive, aerospace, electronic equipment and other fields of parts manufacturing.

The production process of cast magnesium plate generally includes steps such as melting, alloying, mold design and manufacturing, pouring, cooling, cleaning and subsequent processing (e.g. cutting, polishing, heat treatment, etc.). Due to the poor fluidity of magnesium alloys, the casting process is demanding and requires precise control of factors such as temperature, pressure and pouring speed.

It should be noted that although magnesium alloys have many advantages, they also have some disadvantages, such as corrosion resistance will be reduced in specific environments, and the cost is relatively high. Therefore, it is necessary to choose the appropriate material and process according to the specific needs in the actual application.

However, magnesium alloys are highly chemically and electrochemically active and are susceptible to corrosion in the atmosphere, especially in humid and coastal areas, which limits their wide application. Controlling the composition of magnesium alloys and forming a homogeneous organization can improve the corrosion resistance of magnesium alloys, but the final corrosion protection of magnesium alloys often requires surface treatment, and new discoveries and the development of new technologies are needed to obtain self-protective passivation films. At present a variety of surface treatment technology applied to the surface protection of magnesium alloy, in order to change the performance of magnesium alloy, magnesium alloy to expand the field of application of magnesium alloy, improve the service life of magnesium alloy materials, the main common magnesium alloy material surface oxidation dyeing treatment.

One of the chemical dyeing method is to make the dye adsorbed in the pores of the membrane layer, so the configuration of different dyeing solution can be dyed into different colors, with good decorative effect, and the equipment is simple and easy to operate. However, the color of the membrane is less light-resistant and easy to lose color. The anodic oxide film which can be chemically dyed must have the following conditions.

(1) The oxide film must have enough thickness, the specific thickness is determined by the color tone to be dyed, such as dark colors need a thicker film layer, while light colors require a thinner film layer.

(2) The oxidized film must have enough pores and adsorption capacity.

(3) The oxide film should be uniform, the color of the film itself should be colorless or light color and adapt to coloring treatment.

In order to prevent corrosion, this oxidized dyeing treatment is not only applicable to magnesium alloy plates, but also for types such as Magnesium Alloy Rod and Magnesium Alloy Sheet.
