Advantages and Application Fields of Magnesium Alloys
1. Core Advantages
1.Small parts are suitable for hot-chamber die casting machines, while large parts fit cold-chamber die casting machines, with special flame-resistant safety designs required.
2.Die casting temperature ranges from 600 to 650°C; melting energy consumption is slightly lower, yet strict anti-oxidation control is mandatory.
3.High injection speed is required (>6 m/s), suitable for manufacturing thin-walled complex components.
4.The minimum wall thickness can reach 0.3 mm, with superior ultra-thin wall forming capability compared to aluminum alloys.
2. Main Application Fields
New energy automobile industry: steering wheel skeletons, seat frames, gearbox housings, battery cover plates
3C consumer electronics: notebook bottom shells, drone structural brackets, camera internal supports
Aerospace industry: aircraft cabin interior parts, satellite lightweight connecting components
Industrial automation: robotic arm end supports, vibration-resistant sensor housings Medical equipment: portable diagnostic instrument shells, surgical instrument lightweight brackets
Surface Treatment Requirements
Aluminum Alloy
1.A dense natural Al₂O₃ oxide film forms on its surface, delivering excellent basic corrosion resistance.
2.Common surface treatments: shot blasting, sand blasting, anodizing, chemical conversion coating, painting, electroplating
3.Anodic oxide film thickness ranges from 5 to 10 μm, featuring low cost and mature manufacturing process
4. Compatible with various decorative and functional surface finishing solutions
Magnesium Alloy
1.The naturally formed oxide film on magnesium alloy is loose and
porous, resulting in poor basic corrosion resistance.Surface
protection treatment is mandatory.
2.Common surface treatments: Micro-Arc Oxidation (MAO),
anodizing, passivation, spray coating, electroplating
3.MAO ceramic coating thickness ranges from 10 to 50 μm with
outstanding protective performance, yet its cost is approximately 50%
higher than that of aluminum alloy treatment
4. Surface finishing processes demand stricter process control to
prevent surface defects induced by heat treatment
