Magnesium alloy

Introduction

Its machining and corrosion and mechanical properties have many characteristics: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and easy recycling; in addition, there are high Features of thermal and electrical conductivity, non-magnetic, good shielding and non-toxic. Application scope: Magnesium alloy is widely used in portable equipment and automobile industry to achieve the purpose of lightweight.

Although the specific gravity of magnesium alloy is heavier than plastic, its strength and elastic modulus per unit weight are higher than that of plastic. Therefore, with the same strength parts, magnesium alloy parts can be made thinner and lighter than plastic. In addition, because the specific strength of magnesium alloy is higher than that of aluminum alloy and iron, the weight of aluminum or iron parts can be reduced without reducing the strength of the parts. Magnesium alloy has the highest relative strength (ratio of strength to mass). The specific stiffness (ratio of stiffness to mass) is close to aluminum alloy and steel, much higher than engineering plastics.

Surface treatment of die casting


Smooth

The A-level finish adopts a machining method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface.

SPI standard:

A1 A2 A3

Semi-gloss

Grade B finishes use coarse sandpaper to produce parts that are rougher than Grade A parts. Custom molded plastic parts that have undergone B-level finishing have a matte surface texture.

SPI standard:

B1 B2 B3

Matte finish

Grade C finishes use coarse sandstone to produce a rough, uneven surface. The C-level finished injection molded parts have a matte surface texture.

SPI standard:

C1 C2 C3

Textured

Class D finishes use gravel and dry glass beads or oxides to produce a very rough textured finish. Depending on the type of material used, the product can have a satin or matte finish.

SPI standard:

D1 D2 D3
