Hangbo Alloy Group
Shanghai · Est. 2012
From vacuum melting to final inspection, Hangbo Alloy Group controls the full manufacturing chain in-house — backed by an integrated metallurgical laboratory that verifies every heat before it ships.
Our integrated production base converts premium raw material into finished nickel alloy products across all standard forms. Key equipment includes:
Precise control of chemistry and low impurity levels for superalloy melts.
Refines ingot homogeneity and removes inclusions for critical applications.
Open and closed die forging of bars, rings and discs to tight tolerances.
Bar, plate and sheet rolling lines producing consistent dimensional accuracy.
Precision cold drawing and surface peeling for bright, clean finished bars.
Solution treatment, aging and annealing under controlled atmospheres.
Finished-component machining to customer drawings and specifications.
Quality is verified in our on-site metallurgical laboratory. Every heat is chemically and mechanically tested before release:
Full chemical composition analysis of nickel and specialty alloys.
Rapid positive material identification and coating/thickness checks.
Tensile, yield and elongation measurement per ASTM/EN standards.
Brinell, Rockwell and Vickers hardness verification across products.
Low-temperature impact toughness for cryogenic service grades.
Grain-size, phase and microstructure evaluation of prepared samples.
Internal defect and lamination inspection of bars and plates.
On-site grade verification to prevent material mix-up.
As a dedicated nickel alloy manufacturer, Hangbo Alloy Group combines in-house production with full traceability. Every order ships with EN 10204 3.1 mill test certificates, and third-party inspection (SGS, TÜV) can be arranged. Our material serves chemical processing, oil & gas, aerospace and power generation applications where quality is non-negotiable. Review our test reports & traceability process and certifications for details.
