We adopt advanced, short-flow manufacturing technologies to ensure the quality and efficiency of our magnesium wire, adhering to strict quality control standards at every step :
- Raw Material Selection : High-purity magnesium ingots (99.9%+) and alloying elements are selected and tested to ensure compliance with chemical composition requirements. All raw materials undergo strict incoming inspection to eliminate impurities.

- Alloy Melting & Purification : Raw materials are melted in a controlled atmosphere furnace (inert gas protection) to prevent oxidation. The molten alloy is purified to remove impurities, ensuring uniform composition and microstructure. We can achieve magnesium purity up to 99.99% through advanced purification processes.

- Continuous Extrusion : Adopting short-flow continuous extrusion technology, the molten alloy is extruded into wire form in a single pass, eliminating the need for pre-extruded rod materials and multiple drawing passes. The extrusion process is controlled by precision equipment to ensure consistent diameter and surface quality. Extrusion temperature is maintained at 250–500℃, with inert gas protection to prevent oxidation.

-  Drawing & Annealing : For fine wires (≤1.0mm), cold drawing is performed to achieve the desired diameter and mechanical properties. Intermediate annealing is conducted to eliminate processing hardening, ensuring ductility and preventing wire breakage. Cold-drawn wires exhibit higher tensile strength compared to extruded wires.

- Surface Treatment : Optional surface treatments include passivation (to enhance corrosion resistance) and annealing (to improve ductility). The surface is polished to achieve a bright finish, ensuring compatibility with welding and forming processes.

- Quality Inspection : 100% dimensional inspection (using CMM), chemical composition analysis, mechanical property testing (tensile strength, yield strength, elongation), and surface defect inspection are conducted. We also provide Material Test Reports (MTRs) and third-party certification (SGS, ISO) for all orders.

- Packaging & Storage : The finished wire is wound onto spools, packaged in moisture-proof, anti-corrosion packaging (desiccant-sealed cartons, wooden cases) to prevent pre-corrosion during storage and transportation. Each package is labeled with product details (alloy grade, diameter, length, production date) for traceability.
