✅ Product Overview

Our Nb-1Zr Plate is a high-strength niobium zirconium alloy plate containing approximately 1% zirconium, engineered for extreme service conditions involving high temperature, radiation exposure, and liquid-metal environments. This Nb1Zr plate is widely applied in nuclear reactor systems, aerospace thermal structures, and advanced scientific research facilities where conventional refractory metals cannot meet long-term stability requirements.

Compared with commercially pure niobium, Nb-1Zr plate demonstrates superior creep resistance, improved grain boundary stability, and enhanced high-temperature mechanical strength. At the same time, it retains excellent compatibility with alkali metals and ultra-high vacuum environments. As a professional Nb-1Zr plate supplier, we offer fully customized thickness, dimensions, and surface conditions to meet both prototype development and engineering-scale production needs.

For thin gauges, the material may also be supplied as Nb-1Zr sheet, maintaining the same chemical composition and metallurgical control as thicker niobium zirconium plate products.

🧪 Chemical Composition

Typical chemical composition of Niobium 1% Zirconium alloy plate (wt.%):

Element	Content
Nb (Niobium)	Balance
Zr (Zirconium)	0.8 – 1.2%
O (Oxygen)	≤ 0.02%
N (Nitrogen)	≤ 0.01%
C (Carbon)	≤ 0.01%
H (Hydrogen)	≤ 0.0015%

Strict interstitial element control is critical for Nb-1Zr plate performance. Oxygen and nitrogen levels strongly influence ductility, weldability, and fatigue resistance. During melting and hot working, zirconium acts as a scavenger element, binding residual oxygen and improving grain boundary stability, which directly contributes to the long-term creep resistance of Nb1Zr plate at elevated temperatures.

📏 Standards & Specifications

Although the Plate is often supplied under project-specific technical agreements, production and inspection are commonly aligned with the following internationally recognized standards for niobium and niobium alloy products:

🔹 Applicable Reference Standards

ASTM B393 / B393M — Standard Specification for Niobium and Niobium Alloy Strip, Sheet, and Plate
ASTM B392 / B392M — Standard Specification for Niobium and Niobium Alloy Rod and Bar (reference for chemical limits)
ASTM E8 / E8M — Tension Testing of Metallic Materials
ASTM E112 — Determination of Average Grain Size
ASTM E384 — Microindentation Hardness Testing

These standards ensure chemical composition accuracy, mechanical consistency, and microstructural stability of niobium zirconium plate products.

🔹 Nuclear and Aerospace Project Practice

For nuclear and aerospace applications, Nb-1Zr sheet and plate are typically supplied according to:

Customer Technical Specifications (CTS)
Full heat-lot traceability
Project-defined mechanical and metallurgical requirements

In such cases, production may follow internal qualification procedures consistent with:

ASME Section II material property references
Nuclear-grade quality management systems

This ensures reliable long-term performance of Niobium 1% zirconium alloy plate in radiation and liquid-metal environments.

⚙️ Physical and Mechanical Properties

Typical properties of Nb-1Zr plate:

Property	Value
Density	~8.6 g/cm³
Melting Point	> 2400 °C
Tensile Strength (RT)	300 – 450 MPa
Yield Strength (RT)	200 – 300 MPa
Elongation	≥ 20%
High-Temperature Strength	Excellent
Creep Resistance	Significantly improved vs pure Nb
Radiation Stability	Excellent
Thermal Conductivity	Good

At temperatures above 800°C, Nb1Zr plate retains higher load-bearing capability compared with pure niobium due to reduced grain growth and stabilized grain boundaries. This makes Nb-1Zr sheet particularly suitable for components subjected to long-duration thermal stress.
