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.
