Lenovo’s 2024 release of a high-gloss stainless magnesium notebook signals wider acceptance after Shanghai Jiao Tong University demonstrated a salt-spray corrosion rate of merely 0.076 mg/cm²/day, effectively neutralizing historic durability concerns.

Issues Associated with Corrosion and Welding of Magnesium Alloys

Magnesium’s high reactivity accelerates galvanic corrosion when joined to dissimilar metals, complicating welding and service-life predictions. Laboratory work on ultrasonic-laser brazing of AZ31B to Ni-plated stainless successfully improved bond strength, yet fatigue durability still trails conventional steel joints at equivalent thicknesses. Friction-stir welding trials achieved 88% tensile efficiency but highlighted the need for post-weld surface treatments to curb pitting initiation. Until such processes scale, some OEMs maintain a conservative stance, tempering short-term magnesium substitution rates.

Competition from Substitutes

Advanced high-strength steels, carbon-fiber reinforced plastics, and aluminum-lithium alloys offer competing stiffness-to-density ratios without the corrosion baggage. Life-cycle assessments reveal that primary magnesium produced via the Pidgeon process carries higher embedded emissions than recycled aluminum or certain steels^{[3]Source: Lucas Reijnders, “Are Magnesium Alloys Applied in Cars Sustainable and Environmentally Friendly?” mdpi.com} . EV battery integration strategies further complicate decisions: unified cell-to-body architectures can favor aluminum megacastings where foundry capacity already exists. These substitution pressures trim magnesium’s addressable volume, particularly in Western Europe, where OEMs face rigorous sustainability audits.
