Tiangong International

What Tiangong International does

Tiangong International (天工国际有限公司) is a Chinese specialty steel and advanced materials manufacturer founded in 1981 in Danyang, Jiangsu Province, and listed on the Hong Kong Stock Exchange Main Board since July 26, 2007 (Stock Code: 826). The company operates a vertically integrated four-pillar product platform: (1) tool and mould steel, where it became the world's #1 producer with 250,000 tons/year capacity by 2020 and held the #2 global position in mould steel since 2019; (2) powder metallurgy, including China's first industrialized PM production line using third-generation oxygen gas atomization (OGA) and hot isostatic pressing (HIP), yielding proprietary PM-HSS grades (TPM330, TPM5511, TPME23A, and others); (3) cutting tools, produced from in-house HSS and PM-HSS substrates and including HSS taps, drills, end mills, and a 2022-commissioned cemented carbide line (1,000 tons rods, 5M tools, 20M inserts annually); and (4) titanium and titanium alloys (TA1/TA2/TA3/GR4/TA10/TA15/TA18/TC4/TC4ELI/TB13 grades), operated through Beijing Stock Exchange-listed subsidiary Jiangsu Tiangong Technology (920068.BJ, listed May 2025) and emerging titanium alloy powder capacity via Tiangong Titanium Crystal.

The company's core technology stack centers on metallurgical process IP: the EB + VAR titanium melting process (3,500/7,000-ton presses with 1.5/3/10-ton VAR furnaces), the 7,000-ton fast forging line supporting integrated NEV mega-die-casting moulds, near-net shape powder metallurgy with built-in water channels (validated at 30,000–45,000 die-casting shots vs. ~20,000-shot industry benchmark), and second-generation plasma atomization for high-sphericity titanium alloy powders. Revenue is generated through direct B2B sales of physical materials and tools on a quote-based pricing model, distributed through 16 domestic Chinese sales offices, 12+ overseas sales subsidiaries across the US, Italy, Turkey, Czech Republic, Russia, India, South Korea, Thailand, Vietnam, Taiwan, Spain, and Portugal, and an overseas manufacturing facility in Rayong, Thailand (12M+ pieces/year cutting tool capacity).

Tiangong serves industrial customers across 3C electronics (Luxshare Precision, Han's Laser), automotive/NEV integrated die-casting, aerospace (AS9100-certified), mould manufacturing, defence/weapons (quality certified), medical devices (ISO 13485), petrochemical/nuclear energy (high-boron and high-nitrogen steel), and emerging additive manufacturing/3D printing. It employs approximately 3,600 people, holds 267+ patents, and is the only Chinese mould steel company certified by the North American Die Casting Association. The group has dual listings on HKEX (parent, 00826) and BSE (subsidiary, 920068), and operates with global distribution reach across 66+ countries and regions.

Core offering

Tiangong International manufactures and sells four vertically integrated product lines: tool and mould steel (high-speed steel, die steel), powder metallurgy products (jet ingots, HIP ingots, metal powders, PM-HSS grades), cutting tools (drill bits, taps, end mills, reamers made from self-produced HSS/PM-HSS), and titanium and titanium alloys (ingots, plates, tubes, wires, powders). The company is the world's largest tool and mould steel producer with 250,000 tons annual capacity, supplying substrate materials through its own integrated chain to cutting tool customers in automotive, mould manufacturing, aerospace, consumer electronics, and additive manufacturing.

Product overview

Tiangong International operates an integrated, vertically aligned four-pillar product platform spanning Tool and Mould Steel, Powder Metallurgy, Cutting Tools, and Titanium and Titanium Alloys, rather than a single product. The Tool and Mould Steel pillar anchors the company's position as the world's largest tool and mould steel producer (250,000 tons annual capacity since 2020) and supplies substrate HSS/die steel to the in-house Powder Metallurgy business, which in turn feeds third-generation PM-HSS grades (TPM330, TPM5511, TPME23A, etc.) into the Cutting Tools pillar. This vertical integration — "from materials to terminal cutting tools" — gives Tiangong what it describes as the world's most complete cutting tool industrial chain, supported by the Tiangong Precision Tool Research Institute. The Titanium and Titanium Alloys pillar is operated through subsidiary Jiangsu Tiangong Technology Co., Ltd. (920068.BJ, listed May 2025) and supplies consumer electronics, aerospace, marine, chemical, biomedical, and 3D printing markets, with emerging titanium alloy powder capacity (Tiangong Titanium Crystal) targeting metal 3D printing raw materials.
