Double Recognition! Weilaili's High-Temperature Titanium Alloy Powder and EIGA System Earn Provincial Certification

August 20, 2026 News 9887

On August 14, 2026, the Department of Industry and Information Technology of Jiangsu Province released its public notice for the 2026 "Three Firsts and Two New" certification program.

Weilaili's independently developed T70X high-temperature titanium alloy powder for selective laser melting, along with its high-efficiency argon-recovery EIGA atomization system, were both selected—one as a first-batch new material, the other as a new technology and product. This national-level "Little Giant" enterprise specializing in additive manufacturing has now received official provincial recognition in two critical areas: advanced titanium alloys and powder-production equipment.

The T70X is Weilaili's next-generation near-α high-temperature titanium alloy, developed in-house to meet the stringent lightweight and heat-resistance demands of aerospace vehicles operating at increasing Mach numbers. By fine-tuning the alloying element ratios and leveraging multi-element synergy, the team successfully boosted high-temperature performance while suppressing hot-cracking tendencies during printing. The material maintains stable service at 700°C, with a tensile strength of at least 480 MPa at that temperature. It has passed validation on thin-walled parts with a build envelope exceeding 500 mm, achieving minimum wall thicknesses of 0.3 mm, minimal distortion, no cracking after heat treatment, and defect-free inspection results. At a 45° build angle, the surface finish is smooth, and overall printability is comparable to that of TA15 alloy. The T70X is already in use for critical components such as aero-engine blades, casings, integral blisks, and hot-section structural parts for high-speed flight vehicles. Notably, the championship trophy for the "Jiangsu Super League" was 3D printed with this powder, cutting weight by over 50% while becoming even stronger.

The concurrently selected EIGA atomization system integrates efficient argon recovery, high-quality powder production, and multi-material compatibility into a single platform. It features a fully integrated DCS and MES control architecture with remote operation and maintenance support. Its modular, flexible design enables rapid switching between titanium alloys, superalloys, and other materials, while a continuous feeding unit allows uninterrupted production runs. Compared to conventional equipment, this system boosts single-batch output by 40% and increases equipment utilization by more than 50%. Beyond delivering green, low-carbon manufacturing through argon recycling, the EIGA line now has an annual capacity exceeding 2,000 tons, providing robust equipment support for domestic replacement of high-end metal powders and reducing reliance on imports.

Founded in 2015 and backed by Xuzhou Mining Group, Weilaili has achieved 100% independent development of its high-end smart equipment and critical components. The company holds over 200 granted patents and has led or contributed to more than 20 national standards. In 2024, it was accredited as the "Jiangsu Provincial Additive Manufacturing New Materials Engineering Research Center." With a continuous market share of over 35% for three consecutive years, its products are now used in volume production for aircraft engines and spacecraft structural parts, fundamentally changing China's long-standing dependence on imported materials and equipment in additive manufacturing.
