Six National Standards for Aerospace Metal Additive Manufacturing to Take Effect August 1, Covering Full Chain from Powders to Parts, Testing, and Personnel Qualification

2026-07-01 · Impact score: 33

China’s State Administration for Market Regulation and the Standardization Administration have issued six core national standards for metal additive manufacturing, set to take effect on August 1, 2026. The standards cover the entire industrial chain, including upstream metal powder raw materials, laser-deposited titanium alloy components, quality classification of SLM-produced parts, non-destructive testing of internal cavities, and practitioner qualifications. Notably, GB/T 47094-2026 'Zinc and Zinc Alloy Powders for Additive Manufacturing' brings zinc alloy powders into the national standard system for the first time. GB/T 47005-2026 'Technical Specification for Laser Directed Energy Deposition of Titanium Alloy Parts' fills a domestic gap in standardizing large-format deposition titanium aerospace components. GB/T 47006-2026 'Quality Classification and Testing Requirements for Laser Powder Bed Fusion Metal Parts' serves as China’s first national standard for 3D-printed metal part grading, establishing unified red-line defect criteria for porosity and cracks. GB/T 47008-2026 'Industrial Endoscope Inspection Atlas' includes over one hundred standard reference images of internal cavity defects. Additionally, GB/T 47195-2026 'Additive Manufacturing – Technical Specification for Laser Powder Bed Fusion of Aluminum Alloy and Its Composite Parts' will take effect on September 1, 2026.

BLT Files Patent for Ti-6Al-4V-0.25Si Titanium Alloy Powder, Adding Silicon to Optimize High-Temperature Performance

According to information from the China National Intellectual Property Administration, BLT has filed a patent titled 'Ti-6Al-4V-0.25Si Titanium Alloy Powder for Additive Manufacturing and Its Preparation Method, and Titanium Alloy Parts.' By mass percentage, the powder contains 5.5–6.75% Al, 3.5–4.5% V, and 0.1–0.5% Si. By adding trace amounts of silicon to the traditional Ti-6Al-4V alloy, the patent aims to improve the powder's high-temperature performance and printability. In 2025, BLT reported total revenue of RMB 1.852 billion, with revenue from 3D printing raw materials reaching RMB 113 million. This patent represents another strategic move by BLT to extend from being a leader in equipment manufacturing to offering integrated 'equipment + materials,' further enriching its titanium alloy powder product line.

Xi'an's Commercial Space Sector: From 'Power Heart' to 'Satellite Factory', Chain-Driven Breakthrough Aims for ¥100 Billion by 2030

According to a report from Chinanews.com, Xi'an is transitioning from a 'hometown of aerospace propulsion' to a full-chain commercial aerospace hub. The Sixth Academy of China Aerospace Science and Technology Corporation supplies over 98% of the liquid engines for the Long March rocket family, while the Fourth Academy holds over 90% of the market share for commercial rocket solid motors. Leveraging the national team's technology base, Xi'an's private commercial aerospace sector has given rise to niche 'champion' enterprises in areas such as complete satellite development and reusable propulsion. Zhongke Xiguang Aerospace is China's only privately-owned company to achieve complete in-house development of hyperspectral satellite technology, having launched 11 satellites, with the nation's first hyperspectral satellite data asset inclusion on the books in 2025. Tianhui Aerospace focuses on low-cost, reusable liquid rocket engines. Xice Test provides one-stop component screening and testing services. Bright Laser Technologies (BLT) uses metal 3D printing to produce critical, complex components for rocket engines. Xi'an aims to grow its commercial aerospace industry scale to ¥100 billion and have over 150 enterprises above the designated size by 2030.
