TC4 (Ti-6Al-4V) titanium alloy, the most representative α+β dual-phase titanium alloy, is acclaimed as the "space metal" and "ocean metal." Thanks to its outstanding specific strength, excellent corrosion resistance, and favorable biocompatibility, it has become a key material for lightweighting and performance enhancement in high-end equipment.
In the aerospace sector, spherical TC4 powder is an ideal choice for manufacturing large load-bearing structural components of aircraft, engine fan blades, casings, and rocket fuel tanks. Its high specific strength ensures structural rigidity while achieving significant weight reduction, contributing to improved fuel efficiency and payload capacity for aircraft. In the medical device field, TC4 powder, with its elastic modulus close to that of human bone and excellent biocompatibility, is widely used for printing artificial joints, bone implants, and surgical guides, aiding patients in rebuilding healthy lives. In marine engineering and racing, its inherent resistance to seawater and complex environmental corrosion, combined with high fatigue strength, makes it an exceptional material for deep-sea exploration equipment, as well as high-performance racing car connecting rods and suspension components.
Spherical TC4 powder finds wide application in additive manufacturing across multiple fields due to its outstanding material properties:
(1) Exceptionally High Specific Strength and Superior Comprehensive Mechanical Performance
The specific strength (strength-to-density ratio) of TC4 alloy far exceeds that of most high-strength steels and aluminum alloys. It reduces structural weight while withstanding high loads and impacts, and offers excellent fracture toughness and fatigue resistance.
(2) Exceptional Corrosion Resistance and Biocompatibility
It forms a stable, dense oxide layer on its surface in bodily fluids, seawater, and various harsh chemical media, providing long-term protection against pitting and stress corrosion cracking. Its excellent tolerance in the human environment makes it one of the preferred materials for permanent implants.
(3) Broad Process Compatibility
Spherical TC4 powder is perfectly suited for additive manufacturing technologies such as Selective Laser Melting (SLM), Electron Beam Melting (EBM), and Laser-Directed Energy Deposition (LDED). It is also compatible with processes like Powder Metallurgy (PM), Hot Isostatic Pressing (HIP), and laser repair remanufacturing, enabling near-net shaping of complex components with limitless possibilities.
As a domestic manufacturer of high-performance metal powder materials, Saistech (Guangzhou) Co., Ltd. leverages its independently mastered advanced Plasma Rotating Electrode Process (PREP) to produce spherical TC4 powder characterized by high sphericity, low oxygen content, excellent flowability, and minimal satellite particles.
These properties ensure uniform and dense powder spreading during the 3D printing process, along with stable melt pool formation, significantly reducing defects such as porosity and lack of fusion. This provides foundational assurance for achieving high density, superior surface quality, and consistent mechanical performance in the final components.
Saistech is committed to building a comprehensive industrial ecosystem. The company has introduced an integrated service model encompassing "powder preparation – component manufacturing – post-processing," supported by strict adherence to SGS certification and ISO9001 quality management systems. This ensures precise control over every stage from raw materials to finished products.
Saistech is dedicated to providing professional full-industry-chain additive manufacturing solutions to global clients in aerospace, medical devices, automotive manufacturing, consumer electronics, and other sectors. The company continues to drive innovation and breakthroughs in lightweight and high-performance manufacturing.
