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

2026-07-01 · Impact score: 49

According to information from the National Intellectual Property Administration, BLT has filed a patent titled "Ti-6Al-4V-0.25Si Titanium Alloy Powder for Additive Manufacturing, Preparation Method Thereof, and Titanium Alloy Parts." The powder comprises, by mass percentage, 5.5-6.75% Al, 3.5-4.5% V, and 0.1-0.5% Si. By adding trace amounts of silicon to the conventional Ti-6Al-4V alloy, the patent aims to improve the powder's high-temperature performance and printability. In 2025, BLT reported revenue of RMB 1.852 billion, of which RMB 113 million came from 3D printing raw materials. This patent marks another strategic move for BLT as it transitions from a leading equipment manufacturer to an integrated "equipment + materials" player, further enriching its titanium alloy powder product line.

Xi’an Commercial Aerospace: From ‘Power Heart’ to ‘Satellite Factory,’ Chain-Driven Breakthrough Aims for ¥100 Billion by 2030

Xinhua reports that Xi’an is transitioning from 'China's aerospace power hub' to a full commercial aerospace supply chain. The Sixth Academy of Aerospace Science and Technology provides over 98% of the liquid engines for the Long March rocket series, while the Fourth Academy holds more than 90% of the commercial solid rocket motor market. Building on state-owned technology foundations, Xi’an’s private commercial aerospace sector has nurtured niche players in complete satellite manufacturing and reusable propulsion. CAS Xi’an Aerospace is the only Chinese commercial company to achieve fully in-house development of hyperspectral satellites; it has launched 11 satellites and in 2025 completed the nation's first hyperspectral satellite data asset securitization. Tianhui Aerospace focuses on low-cost, reusable liquid rocket engines. Western Test provides one-stop component screening and testing services. BLT, a metal 3D printing firm, locks in complex engine component manufacturing. Xi’an aims to grow its commercial aerospace industry to ¥100 billion and over 150 above-scale enterprises by 2030.

Six National Standards for Metal Additive Manufacturing in Aerospace to Take Effect August 1, Covering Full Chain from Powder to Parts, Testing, and Personnel Certification.

China's State Administration for Market Regulation and the Standardization Administration have released six core national standards for metal additive manufacturing, set to take effect on August 1, 2026. The standards span the entire industry chain, including upstream metal powder feedstock, laser-deposited titanium alloy components, quality classification for SLM parts, non-destructive internal cavity inspection, and personnel certification. Notably, GB/T 47094-2026 'Zinc and Zinc Alloy Powders for Additive Manufacturing' introduces zinc alloy printing powder 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 deposited aerospace titanium components. GB/T 47006-2026 'Quality Classification and Testing Requirements for Laser Powder Bed Fusion Metal Parts' is China's first national grade-based standard for 3D-printed metal parts, establishing unified thresholds for defects such as pores and cracks. GB/T 47008-2026 'Industrial Endoscope Inspection Atlas' includes over one hundred standard images of internal cavity defects. Additionally, GB/T 47195-2026 'Technical Specification for Additive Manufacturing of Laser Powder Bed Fusion Aluminum Alloy and Its Composite Parts' will take effect on September 1, 2026.
