LIGHTWEIGHT METALS · GRADE-AND-FORM CONTROLLED SOURCING
Magnesium & Magnesium Alloys — Technical Sourcing
Sourcing of magnesium sheet, plate, strip, ribbon, foil, wire, bar, rod, tube and special profiles by verified alloy, product standard and temper.
MNK-G.S.A develops each supply route from the required designation, manufacturing route, dimensions, quantity, inspection documents and destination. Listed grades and forms describe a sourcing portfolio—not universal stock or automatic availability of every grade in every form.
Grade, Form and Condition Must Match
- A magnesium designation does not by itself define whether the product is rolled, extruded, drawn, forged or cast.
- The quotation must retain the exact alloy suffix, temper or heat-treatment condition, product form, dimensions and governing specification.
- Wrought and cast variants with related trade names are not automatically interchangeable. For example, a wrought Elektron 43 or WE43 route must not be substituted by a cast WE43B route without engineering approval.
- Availability is confirmed as one complete combination of grade, form, size, condition, quantity and certificate requirements.
Magnesium Grade Portfolio
The following portfolio combines established general-purpose and special wrought families evidenced in current producer routes. It is a broad RFQ scope, not a claim that each grade is stocked or producible in every form.
| Family | Grades and designations handled on inquiry | Route control |
|---|---|---|
| Unalloyed and low-alloy magnesium | Pure Mg, M1A | Purity, product form and applicable composition standard must be stated |
| AZ general-purpose wrought alloys | AZ31B, AZ61A, AZ80A, AZM | Exact suffix and temper are required; AZ31B has the clearest public sheet-and-plate route |
| ZK, ZM and ZW wrought alloys | ZK60A, ZM21, ZW3 | Extrusion, tube, forging or rolled route is confirmed from the manufacturer and specification |
| Rare-earth and high-performance alloys | WE43, WE54, Elektron 43, Elektron 675, Elektron 21 | Trade name, formal alloy designation, wrought or cast route, heat treatment and producer document must agree |
| Custom and customer-defined alloys | Producer-developed or customer-specified compositions | Only against an approved datasheet, drawing, specification and inspection plan |
Grade-list note: “all grades” on this page means the complete magnesium portfolio MNK-G.S.A is prepared to investigate through qualified sources. It does not mean every historical alloy designation or universal availability. Additional grades may be sourced when the customer provides the governing specification or an approved composition.
Product Forms
Sheet & Plate
AZ31B sheet and plate may be sourced in O, H24 or H26 when ASTM B90/B90M-21 governs. ISO 23700:2021 provides a separate international framework for rolled plate and sheet. ZM21 and special rolled-plate routes are reviewed against producer documents.
Strip & Coil
Rolled strip and coil inquiries are developed by grade, thickness, width, coil weight, inside and outside diameter, edge condition, temper and surface finish. JIS H 4201:2018 explicitly covers magnesium-alloy sheets, plates and strips.
Ribbon & Foil
Narrow ribbon, narrow strip and foil are special mill or conversion routes. Exact thickness, width, edge, surface, temper and coil geometry must be qualified; no universal grade or minimum gauge is assumed.
Wire
Extruded or drawn wire is sourced by exact alloy, diameter, temper, coil or straight-length form, surface and test requirements. ASTM B107/B107M-13(2021) and JIS H 4203:2025 provide product-form frameworks; welding wire requires a separate consumable classification.
Bar & Rod
Round, square or rectangular bar, rod, solid sections and machining stock are reviewed by diameter or cross-section, length, straightness, temper and inspection. One verified producer route publishes round bar from 1.6 to 200 mm and lengths from 25 mm to 6 m; this is a manufacturing example, not guaranteed stock.
Tube & Hollow Section
Seamless round tube, drawn tube, hollow extrusion and custom profile inquiries require outside dimensions, wall, length, tolerances and route. ISO 23694:2021 and JIS H 4202:2025 apply to defined extruded or drawn tube scopes.
Standards by Product Form
| Standard | Relevant scope | Quotation control |
|---|---|---|
| ASTM B90/B90M-21 | AZ31B sheet and plate in O, H24 and H26 | Do not extend this evidence to every grade or to strip, wire or tube |
| ASTM B107/B107M-13(2021) | Extruded bar, rod, profile, tube and wire | Confirm that the requested alloy and temper are within the current standard table |
| ISO 3116:2019 | Wrought bars, sections, tubes, forgings, plate and sheet | Still published but expected to be replaced; verify the edition at quotation |
| ISO 23694:2021 | Extruded bars and seamless round tubes for general engineering | Confirm shape, route and inspection/delivery conditions |
| ISO 23700:2021 | Rolled plates and sheets | Confirm grade, temper, tolerances, heat treatment and delivery condition |
| JIS H 4201:2018 | Rolled sheets, plates and strips | Useful when strip is explicitly required |
| JIS H 4202:2025 | Extruded and drawn seamless tubes | Current 2025 product-form route |
| JIS H 4203:2025 | Extruded and drawn bars and wires | Current 2025 product-form route |
Application Context
Magnesium alloys may be considered for weight-sensitive aerospace, transport, motorsport, electronics, tooling, prototype and engineered-component requirements. Corrosion environment, fire and machining controls, joining method, surface protection, galvanic interaction, load and service temperature must be reviewed for the exact grade and component.
