Magnesium machining

This page presents basic guidelines for Magnesium machining to help improve part manufacturability, enhance appearance, and reduce overall production time.

Characteristics of magnesium alloys

Mainly used in aerospace, electronic communications, military, medical and other industries.

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 to recycle; in addition, it also has the characteristics of high thermal conductivity and electrical conductivity, non-magnetic, good shielding, non-toxic and so on.

Magnesium alloys are the lightest structural metals with a high strength-to-weight ratio. Magnesium is the lightest structural metal with a high strength-to-weight ratio

Processing Type smooth Semi-gloss matte Textured
Precision Die Casting A grade finish is made with a diamond polishing process that produces a shiny finish on injection molded parts. Grade B finishes use coarse sandpaper to produce rougher parts than Grade A parts. Custom-molded plastic parts with a B-grade finish have a matte surface texture. Grade C finishes use coarse grit to create a rough, uneven surface. C-finished injection molded parts have a matte surface texture. Grade D finishes use grit and dried glass beads or oxides to create a very rough textured finish. Depending on the type of material used, the product can have a satin or matte finish.
