The 2-series seamless aluminum tube is a high-strength duralumin that can be age-hardened and welded, and it exhibits excellent machinability.

The 2-series aluminum alloys are characterized by relatively high hardness, with copper being the principal alloying element at a content of approximately 3–5%. 2-series seamless aluminum tubes are currently seldom used in conventional industrial applications. In China, there are only a few manufacturers producing 2-series alloys, and their product quality still falls short of international standards. At present, imported aluminum sheet is primarily supplied by producers in the United States, South Korea, and Germany. As China’s aerospace sector continues to develop, the production technology for 2-series aluminum alloys will be further advanced.

2-series seamless aluminum tube inventory: LY12, LY12CZ, 2A12, 2A12-T4, 2024, 2024-T4, 2024-T351, and more—T4, T6.

H13 mandrel


The mandrel is a key rolling tool in the seamless steel pipe rolling process, significantly influencing product quality and rolling costs. In hot‑rolling lines, mandrel consumption accounts for more than 50% of the total tooling expenses across the entire production line. The company’s newly developed composite mandrel can substantially reduce rolling costs and shorten the procurement lead time for seamless steel pipes—without compromising product quality. Users can flexibly select the appropriate mandrel model based on the mill type and specific production conditions.

Composite mandrel


The mandrel is a key rolling tool in the seamless steel pipe production process, significantly influencing both product quality and rolling costs. In hot‑rolling lines, mandrel consumption accounts for more than 50% of the total tooling expenses across the entire production line.
