Magnesium alloys for CNC-machined weight-sensitive housings and structural components. Magnesium offers low density but requires a dedicated review of corrosion protection and machining controls. It should not be treated as a direct aluminum replacement.
How should I select the grade?
Magnesium offers low density but requires a dedicated review of corrosion protection and machining controls. It should not be treated as a direct aluminum replacement. Material availability, stock size and certificate requirements are confirmed during quotation; a listed grade is not a stock guarantee.
What affects machining and inspection?
Review alloy designation, coating system, galvanic contact and chip-management controls. Functional tolerances depend on part geometry, material condition, fixturing and measurement method, not only the material family.
What should I specify for finishing?
State the finish standard, thickness, color or texture, masking and functional surfaces. Consider coating build in fits and threads. Approve any material or finishing substitution in writing.
Material quotation checklist
Send the exact grade and condition, 2D drawing, STEP model, quantity, critical features, service environment and traceability requirements. Tecpreva can review machining suitability and proposed alternatives before production.
