Aluminum-magnesium alloy semi-solid extrusion

Mar 12,2026

1.2888 material barrel and screw, specially designed for aluminum-magnesium alloy extrusion. The semi-solid extrusion of aluminum-magnesium alloy involves high temperatures, high pressures and severe wear, which are conditions that ordinary barrel screws cannot withstand. To achieve stable production lines, long service life and reduced downtime, the material is the key factor.
1.2888 German-made high-alloy hot-formed die steel, containing precious alloys such as cobalt, tungsten, and chromium, is resistant to high temperatures, has excellent red hardness, is resistant to creep, and is wear-resistant. It maintains dimensional stability under semi-solid extrusion conditions, and is not prone to deformation or cracking.
Compared with ordinary nitrided steel and bimetallic screws:
 - The initial cost is slightly higher, but the lifespan is longer and the failure rate is lower.
 - It reduces downtime for component replacement, significantly improving production efficiency.
 - It is suitable for high-end production lines with high value-added and high stability requirements.
Shanghai Yuanyuan Kang focuses on the research and production of 1.2888 material machine barrel screws. It has provided stable supplies to customers both at home and abroad for many years, with export-level craftsmanship and reliable quality. Specifically designed for semi-solid extrusion of aluminum-magnesium alloys, from materials to heat treatment and precision processing, it follows strict standards throughout the process.
