Kowalker was founded in 2008, with its headquarters located in the core area of Shanghai International Steel Service Center. It is a provider of high-end metal material solutions integrating processing and sales. As a leading enterprise in the professional metal processing field in the Yangtze River Delta region, the company has been deeply engaged in the field of special metal materials for 18 years and has established connections with many well-known steel mills at home and abroad. Such as Baosteel Co., LTD., ArcelorMittal, Nippon Steel & Sumitomo Metal, POSCO, Hastelloy of the United States, JFE Steel Co., LTD., U.S. Steel, ThyssenKrupp, CITIC Pacific, Taiyuan Iron & Steel Group, BaoTI Co., LTD., Southwest Aluminum, etc. And it serves many end users, such as China National Nuclear Corporation, China National Petroleum Corporation, China Petroleum & Chemical Corporation, CRRC, Mercedes-Benz, BMW, Audi, Great Wall, Geely and other enterprises. Build an industrial matrix covering multiple metal categories and all forms of products.

Kowalker Materials System: Focusing on the three fundamental material systems of carbon steel, alloy steel and stainless steel, it also lays out strategic emerging materials such as high-temperature alloys (GH series), precision alloys (1J series), titanium alloys (TC4/TC11, etc.), and aluminum alloys (2 series /7 series).

The product forms cover precision bars (Φ3-600mm), ultra-fine wires (Φ0.05-40mm), special strips (0.01-3mm), custom tubes (capillary tubes/special-shaped tubes), high-end plates (thin plates/medium and thick plates), as well as processing various special-shaped materials.

Kowalker offers a wide range of metal material processing services: including customized heat treatment (vacuum/protective gas/quenching and tempering/solution aging), precision drawing (fine wire drawing/coil drawing/bar drawing /±0.01mm accuracy), surface treatment (peeling/polishing/grinding), and other value-added services. 3.0 Intelligent heat treatment technology: Through the AI temperature control system to achieve gradient heat treatment, it helps materials to be more efficient, and the third-generation micron-level wire drawing process; We have broken through the bottleneck of continuous production of 0.02mm extremely fine wire materials, with a surface roughness of Ra0.2μm. We have established a full-process quality traceability system and equipped it with testing equipment such as German SPECTRO spectrometers and Zeiss metallographic microscopes. The products are widely applied in: aerospace (engine components/avionics connectors), medical devices (implantable devices/surgical tools), new energy (automobiles/fuel cell bipolar plates/hydrogen storage materials), and precision electronics (semiconductor lead frames/connectors).
