Melting process
Induction melting and electric slag remelting: Induction melting is performed first, followed by electric slag remelting to ensure uniformity of composition and reduce impurities.
Vacuum induction melting and electric slag remelting: Induction melting is carried out in a vacuum environment, followed by electric slag remelting to further improve the purity of the material.
Vacuum induction melting and vacuum arc remelting: Induction melting is carried out in a vacuum environment, followed by vacuum arc remelting to ensure high purity and performance of the material.
Vacuum induction melting: NIMONIC 90 Alloy Directly conducting induction melting in a vacuum environment, suitable for applications that require extremely high material purity.
Our factory
Our factory is located in a major industrial hub in China, equipped with modern production facilities and a comprehensive quality management system. Covering an area of 25,000 square meters, the factory is outfitted with advanced smelting, forging, rolling, and precision machining production lines, specializing in the research, development, and manufacturing of nickel-based alloys, high-temperature alloys, and special copper alloys. We strictly adhere to the ISO 9001 quality management system and leverage laboratory equipment such as spectral analysis, metallographic testing, and mechanical property testing to ensure end-to-end quality control from raw materials to finished products. Additionally, the factory supports large-scale customized production capabilities, catering to the precision material needs of global clients in high-end sectors such as aerospace, energy and chemical engineering, and shipbuilding.

Product packaging
To ensure that our nickel-based alloy products (such as Hastelloy, Monel, and Inconel series) arrive in optimal condition for global customers, we employ an industrial-grade, multi-layered professional packaging solution:
Inner Layer Protection: Each piece of bar, plate, or tube is tightly wrapped with anti-rust oil paper/VCI film to effectively isolate moisture and prevent surface oxidation and corrosion.
Middle Layer Reinforcement: Customized foam corner protectors and waterproof stretch film are used to secure the products, preventing friction and collisions during transportation. Precision components are individually packed in blister trays or separate plastic boxes to ensure structural integrity.
Outer Layer Identification: Products are packaged in high-strength waterproof woven bags or wooden/steel crates, with clear product labels (material grade, dimensions, heat number, standard) and international shipping symbols (moisture-proof, upward, fragile, etc.) attached, complying with export packaging standards.
Full Traceability: Each batch includes a unique logistics barcode and quality certificate, enabling end-to-end traceability and ensuring transparent and reliable delivery.
We commit to providing comprehensive protection for every nickel-based alloy product from factory to your hands, guaranteeing consistent quality throughout.
