Material
Magnesium
Magnesium is one of the lightest structural engineering metals and is used in applications where weight reduction is a major design objective. Magnesium alloys are commonly considered for automotive components, electronics housings, aerospace structures, and industrial assemblies requiring low density and efficient production.
Material overview
Magnesium alloys offer low density, favorable castability in selected compositions, and useful strength-to-weight characteristics.
Their performance depends on alloy composition, manufacturing method, surface protection, and operating environment.
Common grades include:
- AZ91D: A widely used magnesium die casting alloy offering good castability and mechanical performance.
- AM60B: Selected for components requiring improved ductility and energy absorption.
- AZ31B: A wrought magnesium alloy used in sheet, plate, and selected formed components.
- ZK60A: A higher-strength wrought alloy used in specialized structural applications.
Manufacturing processes include die casting, CNC milling, turning, forming, and selected extrusion operations.
Magnesium requires careful process planning because of its chemical reactivity, corrosion sensitivity, and machining fire hazards. Appropriate chip management, tooling, and fire-safety controls are essential.
Typical applications include lightweight housings, automotive structural components, portable equipment frames, and specialized aerospace hardware.
Surface treatments may include conversion coatings, anodizing systems designed for magnesium, painting, and protective coating combinations.
RFQs should include the exact alloy grade, material condition, geometry, dimensional tolerances, surface protection requirements, quantity, and inspection criteria.
Buyers should also identify environmental exposure, galvanic corrosion risks, and applicable flammability or regulatory requirements.
Metraxio supports magnesium manufacturing RFQs with clearly documented technical and quality requirements.
