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:
Open and closed die forging of bars, rings and discs to tight tolerances.
Precise control of chemistry and low impurity levels for superalloy melts.
Refines ingot homogeneity and removes inclusions for critical applications.
Hot and cold rolling of plates and sheets with precise gauge and flatness control.
Cold rolling of precision strip and coil to tight thickness and width tolerances.
Hot piercing and cold pilger rolling of seamless tubes to tight dimensional tolerances.
Solution treatment, aging and annealing under controlled atmospheres.
Multi-axis machining of finished components to customer drawings and tight tolerances.
Fiber laser cutting of plates, sheets and profiles with narrow kerf and clean edges.
Quality is verified in our on-site metallurgical laboratory. Every heat is chemically and mechanically tested before release:
Our desktop optical emission spectrometer (OES) delivers full chemical composition analysis of nickel alloys, Hastelloy, Inconel and specialty superalloys, ensuring every heat meets certified material specifications.
A portable XRF spectrometer for fast on-site positive material identification (PMI), preventing grade mix-ups across nickel alloy bars, plates and seamless tubes before shipment.
Ultrasonic non-destructive testing (UT) equipment inspects internal defects, inclusions and laminations in nickel alloy bars, plates and tubes without damaging the product.
Bench hardness testers perform Brinell, Rockwell and Vickers measurements to verify the hardness of finished nickel alloy products in line with ASTM and EN standards.
Our universal tensile testing machine measures tensile strength, yield strength and elongation of nickel alloy materials to guarantee consistent mechanical properties for critical applications.
Precision calipers, micrometers and gauges verify dimensions, tolerances and surface finish of machined nickel alloy components to meet tight customer drawings.
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.
