What is Magnesium Alloy Extrusions?
Magnesium Alloy Extrusions is magnesium alloy supplied in extrusions form — extrusions are profiles pushed through a die to a constant cross-section — bar, tube, angle, channel and custom shapes — used where a rolled section is not available. Steelco Metal & Alloys stocks magnesium alloy extrusions in Mumbai, India in Extrusions: To section drawing, produced to ASTM B107, in grades including Magnesium AZ31B, Magnesium AZ61A, Magnesium AZ80A, Magnesium AZ91D. Every dispatch carries an EN 10204 3.1 mill test certificate (3.2 with third-party witness on request), PMI verification and heat-number traceability, and we export to more than 40 countries.

Why Choose Magnesium Alloy Extrusions
Straightness and tolerance
Extrusions is supplied to h9 / h11 tolerance with straightness within 1 mm per metre, ready for direct machining without pre-straightening.
Full-length traceability
Every bar is stencilled with heat number, grade and specification so the mill test certificate can be matched to the piece on your shop floor.
Cut to your length
Bandsaw cutting to ±1 mm on lengths from 100 mm upwards, so you pay for the metal you use rather than a full mill length.

Grade chemistry and mechanical properties supplied in magnesium alloy extrusions.
Chemical composition and mechanical properties are grade properties, not form properties — the same grade keeps the same chemistry whether it is supplied as sheet, plate or coil. The tables below list the specified limits for each grade we stock in magnesium alloy extrusions, tested and certified to ASTM B107. Values are weight percent (maximum unless a range is shown); mechanical values are minima in the annealed condition.
