Common Magnesium Types for CNC Machining
Select an alloy according to weight, strength, corrosion exposure, forming requirements and operating temperature.
AZ91D
La forzaAbout 9% aluminum, with strong hardness and relatively low cost. Published Knoop hardness: HK 76.2.
AZ31
FormabilitàAbout 3% aluminum and good plasticity, with lower strength and hardness than AZ91D. Published HK 51.1.
ZK60
Load BearingA high-strength, wear-resistant option for load-bearing structures; its relative brittleness makes machining harder.
Mg-Mn
CorrosionOffers good corrosion resistance for chemical equipment and parts exposed to humid environments.
Mg-RE
Alta temperaturaRare-earth-containing alloys with more stable high-temperature performance for engine components.
Mg-Li
Lowest DensityAn extremely low-density metallic structural material for demanding lightweight applications.
Magnesium CNC Machining Parts
Examples from the original page show precision components, thermal structures, turbine forms and multi-axis machining capability.
Surface Finishes for Magnesium Parts
Based on Weldo's published Esperienza di lavorazione CNC, these processes improve corrosion resistance, wear behavior, appearance or coating adhesion.
Corrosion Protection
Chemical conversion coating, anodizing and Alodine improve protection and coating adhesion.
Surface Texture
Polishing, sand blasting and brushing adjust roughness, reflectivity and visual texture.
Rivestimenti protettivi
Powder coating and electroplating add dense protective or functional surface layers.
Process Enhancement
Black oxide and heat treatment are selected where the alloy and performance target permit.
Why Work With Weldo ?
Multi-axis machining, DFM support and coordinated inspection help move magnesium projects from sample approval to repeat production.
Multi-axis capacity supports consistency in volume production.
Structural feedback helps reduce cost and improve machining efficiency.
CMM and related systems support dimensional verification.
Samples from 1 day; production commonly ships in 3–15 days.
Domande frequenti
Concise guidance based on the original page’s machining, finishing and safety notes.
Which tools and cutting parameters suit magnesium alloys?
Fine- or ultra-fine-grain carbide tools are common; diamond-coated tools suit volume work. The original guidance favors rake and clearance angles above 10°, cutting speed above 300 m/min and feed above 0.1 mm/tooth, while preventing local heat buildup.
Which surface treatments are commonly used after machining?
Options include chemical conversion, anodizing, micro-arc oxidation and properly pretreated Ni/Cu/Cr electroplating. Selection depends on corrosion, wear, appearance and service conditions.
Does magnesium CNC machining involve safety risks?
Yes. Fine chips and dust can ignite near 500°C. Use appropriate wet cutting, fire suppression and dust collection; clean chips regularly and never blow them around with compressed air.
